Title: Magnetic disc device
Inventor: MINAMI SHIGEO
IPC: G11B19/20
Filed: 1984-07-30
Abstract: PURPOSE:To make the contact state between the spindle and the earth pad constant regardless of the operating time by providing a screw threads in a direction causing a parallel movement detaching the earth pad from the spindle to a male screw when the male screw is turned in the turning direction of the spindle. CONSTITUTION:If a friction between the spindle 3 and the earth pad 8 is increased because of any cause, since the torque given from the spindle 3 to the earth pad 8 is increased, a male screw 9 is about to be turned by a magnitude proportional to the increased friction force, the male screw 9 is moved in parallel axial as the turning proceeds. Since the movement is directed to detach the earth pad 8 from the spindle 3, the friction force between the spindle 3 and the earth pad 8 is decreased. Then the male screw 9 is made stable at a new turning angle where the friction between the spindle 3 and the earth pad 8 balances with the restoring force of a torsional spiral spring 10. Thus, the contact state between the spindle 3 and the earth pad 8 is made stable and noise or abnormal vibration is hardly caused to the earth pad 8 and the spindle 3 because of wear of the earth pad 8.

Title: Optical disk apparatus
Inventor: KASHIWA HIROSHI
IPC: G11B7/00
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To improve an ID protection method for a double-faced optical disc divided to zones. SOLUTION: Additional recording of a preamble block and a postamble block to an optical disc 8 is abolished. An ID obtained by subtracting 1 from a correct ID of a leading block of a plurality of data blocks constituting a data format of each of a pair of optical heads 7 and an ID obtained by adding 1 to a correct ID of a last block are calculated beforehand for each zone to be reproduced by a microcomputer 1. The calculated IDs are supplied as an ID of a virtual data block to a set of ID protection circuits 11. If an ID of a certain block has an error, but IDs of the blocks before and after the block have no error, the ID protection circuits 11 correct the ID of the error block to a correct ID obtained by adding 1 to the ID of the preceding block.

Title: Sector detecting circuit
Inventor: OKADA MINORU
IPC: G11B27/22
Filed: 1982-09-14
Abstract: PURPOSE:To always generate a sector pulse in a correct way and to detect assuredly a sector, by generating a tentative sector pulse based on an estimation in case no read pulse is generated. CONSTITUTION:An erasion part detecting part 1 generates a detecting signal E and sets an FF 2 when a servo sector signal erasion part is detected in a count period of a prescribed number of clock C. Then an FF 5 is reset via an AND circuit 3 when a read pulse RP is generated, and at the same time the FF 2 is also reset. Then a sector pulse SP1 of a high level is delivered from an AND gate 6 to which the output Q of the FF 5 is applied as well as from the gate 3. In case the pulse RP is not delivered due to noises, etc., a tentative sector pulse SP3 is delivered from an AND gate 7 by the output Q of the FF 5, the output Q' of the FF2 and a decoding output D3 obtained on the basis of the count value of a prescribed number of clocks C of an inter-sector counting circuit 9. Therefore the sector pulse is always generated in a correct way, and a sector is assuredly detected to ensure the correct positioning of a head.

Title: Pilot signal discrimination circuit
Inventor: FUNAMOTO TARO
IPC: H04N5/60
Filed: 1988-06-28
Abstract: PURPOSE:To eliminate impulsive noise by providing a comparator comparing a quantized pilot signal input data and a threshold value data and a shift register with a tap or the like receiving its output. CONSTITUTION:A comparator 1 compares the quantity of an input pilot signal data X(n) quantized into m-bit and a threshold value data T. A shift register 2 with a tap stores and outputs the past 4 comparison results. An AND gate 3 receives the present comparison result and the past 4 comparison results, and when all are true, a true output is outputted and if even one level is false, a false output is given. A NO gate 4 outputs a true signal when all are false and outputs a false when even one is false. An RSFF5 keeps outputting a true signal if the output of the gate 3 is true and keeps outputting a false signal if the output of the gate 4 is true. Then the output of the FF 5 is outputted as a pilot signal discrimination result.

Title: Automatic sluice door
Inventor: ARAGADA KUNIKAZU
IPC: E02B7/20
Filed: 1982-09-14
Abstract: PURPOSE:To automatically control the amount of divergent water by a method in which a siphon having openings on both upstream and downstream sides is provided to the sluice door, while the door is vertically moved by a negative pressure generated in the siphon, and the negative pressure is controlled by the water level of the water stream to be controlled. CONSTITUTION:When winch 14 is loosened, a door 3 fully closed is opened until the opening of a water level regulating tube 23 is submerged into water. Water stream is also discharged from an outlet 6 into the downstream side chamber 29 of a siphone 12 provided to the door 3, and the air of the siphone 12 is mixed in the water and discharged to the downstream side. For this reason, the inside of the siphone 12 becomes of a negative pressure, and the water level in the siphon chamber is raised by the negative pressure and further raised by the discharge of water even from the outlet 6 at higher level. Since the top plate 10 is pulled downwards by the negative pressure, the door 3 is slightly closed, the level of divergent water is lowered, and the water level regulating tube 23 is exposed to the air. When a little amount of air is further supplied and the negative pressure is lowered, the movement of the door 3 is stopped, thereby the level of the divergent water 22 is adjusted at the height of the tube 23.

Title: Laser beam welding method
Inventor: KATAYAMA HIROSUKE
IPC: B23K26/21
Filed: 1985-07-22
Abstract: PURPOSE:To increase the quality in welding by stopping the movement of a laser beam at the welding terminal part and by stopping the irradiation thereof with its continuation for the prescribed time. CONSTITUTION:A welding is performed by abutting the works 1, 2 composed of metallic materials each other and by irradiating a laser beam. In this case, a welding zone 3 is formed by relatively moving a laser work head along the butt part from the welding start position 3a of the welding zone 3 upto the terminal position 3b. With the arrival of the laser work head at the welding terminal position 3b the movement of the laser work head is immediately stopped and after continuing the irradiation of the laser beam for the prescribed time of 1-2sec etc. it is stopped. The energy quantity at the laser beam irradiating point 3c is therefore increased and the penetration of base metals 1, 2 is deepened. The formation of the crater having a notch is thus prevented and the welding quality at the terminal is increased.

Title: Magnetic recording and reproducing device
Inventor: MASUMOTO MASARU
IPC: G11B15/087
Filed: 1986-07-07
Abstract: PURPOSE:To prevent the misdetection due to the miserasion, etc., by separating the signal of a prescribed frequency from a magnetic head and allowing to read an output signal out of the magnetic head in response to the level of the separated signal. CONSTITUTION:A BPF 20 serving as a separating circuit separates an erasion signal f4 from the output signal of a magnetic head 1. A detecting circuit 21 which detects the level of the signal f4 consists of a peak detecting circuit 22, a holding circuit 23, a comparator 24 and an inverting circuit 25. An AND circuit 26 serving as a control circuit outputs the output of the comparator 3 to a counter 4 response to the output of the circuit 21. The signal f4 does not exist at the positions where the original synchronizing signals f2 and f3 are recorded and therefore the circuit 26 is conducted. Thus it is possible to detect both signals f2 and f3 by integrating the output of the head 1 via an integration circuit 2 and counting the signals undergone the waveform shaping through the comparator 3 by a counter 4 via the circuit 26.

Title: Inverted-type aerosol product
Inventor: UCHIYAMA TAKESHI
IPC: B65D83/44
Filed: 1994-06-20
Abstract: PURPOSE:To prevent an aerosol valve from being clogged due to foreign materials such as deposit or agglomeration to obtain a good spraying state constantly by providing an inlet opened into a pressure-resistant container for taking out contents in the container on a wall of the valve wherein a filter member is in contact with the inlet. CONSTITUTION:When a stem 21 is pushed up toward a reservoir 29 against a spring 25 by an actuator, a stem opening 21a is opened inside the reservoir 29 so that the reservoir 29 is connected with an atmosphere and contents in a pressure-resistant container 11 are sprayed outside. At this time, the contents in the container 11 pass from a gap of a filter support member 33 through a filter member 31 and enter the reservoir 29 from a valve body inlet 27a. Therefore, even if foreign materials such as deposit or agglomerated particles having a particle diameter which would not exist inherently are generated or exist in the contents, the foreign materials are filtered by the filter member 31 and removed, so that respective parts of the valve body inlet 27a and the reservoir 29 are prevented from being clogged.

Title: Production of oil well steel pipe having high collapse strength
Inventor: TANIDA MUTSUMI
IPC: B21D3/16
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To stably provide high collapse strength by computing initial cooling temp. so that the inside circumferential residual compressive stress of a steel pipe, resultant from warm straightening, becomes equal to residual tensile stress at water cooling and controlling the amount of cooling water. SOLUTION: A quenched-and-tempered steel pipe is subjected to warm straightening at a temp. between 150 deg.C and tempering temp. The inside circumferential residual compressive stress of the steel pipe, resultant from warm straightening, is determined from the relation with previously determined rolling reduction of outside diameter at straightening, and the initial steel pipe cooling temp., where the inside circumferential residual tensile stress of the steel pipe at water cooling becomes equal to the computed residual compressive stress, is computed on the basis of an equation. The amount of cooling water is controlled on the basis of the above, and the final inside circumferential residual compressive stress of the steel pipe is reduced.  The residual outside-tensile and inside-compressive stress of the steel tube, resultant from warm straightening, is compensated with the residual outside-compressive and inside-tensile stress of the steel pipe, resultant from water cooling, and, as a result, the final residual stress of the steel pipe can be reduced and collapse strength can be improved.

Abstract: PROBLEM TO BE SOLVED: To prevent a panel from being completely doglegged by a thermal deformation and the subsequent welding work from becoming difficult, by a method wherein a plurality of the spot-welded parts of the panel are provided and both ends of grooves are extended to the sides of connection flanges. SOLUTION: Spot-welding parts 11 for jointing one pair of fellow panel boards 8 with each other are provided not only on both sides of connection flanges 8a and 8b but at four places along the circumference of each flange at positions encircling the flanges 8a and 8b, but though the strength of the peripheries of the flanges 8a and 8b is increased by these welding parts 11, the strength between the flanges 8a and 8b and grooves 10 is weak and there is a possibility that a panel is bent at the positions of the grooves 10. Owing to this, the two grooves 10 on both sides of the flanges 8a and 8b out of the grooves 10 which are the positions not corresponding to the flanges 8a and 8b are extended to the sides of the flanges 8a and 8b, in short, to the welding parts 11.  As a result, the need to provide a reinforcing sheet on the inside of the end panel of the panel is eliminated and the bent of the panel due to a thermal strain is prevented from being generated.

Title: Sample stage of scanning type electron microscope
Inventor: HAMADA TOSHIMITSU
IPC: G01N23/22
Filed: 1982-09-17
Abstract: PURPOSE:To make it possible to easily correct the magnification at arbitrary time without stopping evacuation operation for exchanging an sample by burrying one or plural standard samples for magnification correction in the sample stage of a scanning electron microscope. CONSTITUTION:The height of a standard sample 3 for magnification correction is set such that the difference between distances of a sample 2 to be scanned and the standard sample 3 from an objective lens 4 falls into the depth of a field of view, e.g., 10mum or so in the magnification of 1,000 times, and the standard sample 3 is burried into the conveying table 1 of the sample stage. Accordingly, it is possible to allow the sample 2 to enter the field of view of a microscope by moving the sample stage to permit the standard sample 3 to fall into the field of view, correcting its magnification, and thereafter again moving the sample stage, thus enabling the magnification correction to be performed at arbitrary time without stopping the vacuum evacuation operation for sample replacement.
