Title: Magnetic recording and reproducing device
Inventor: SHIMURA MASAYUKI
IPC: G11B20/24
Filed: 1984-05-30
Abstract: PURPOSE:To eliminate a transient noise generated in a muting part by a noise reducing circuit by muting a sound signal muted at a joint of a track, in a muting period including the previous muting period, after passing the noise reducing circuit. CONSTITUTION:Delaying circuits 13, 14 of the first controlling circuit 11a are triggered by a leading edge part of a head switching signal, and the circuit 13 and the circuit 14 form a signal having a pulse width which is shorter than by tau1 time than the head switching signal, and a signal having a pulse width which is shorter by tau1 time than a two piece portion of the head switching signal, respectively. Delaying circuits 15, 16 are triggered by a leading edge part of an output of inversion circuits 13a, 14a, form a pulse which is continued for 2tau1 time, and supply it to a muting circuit 11. A delaying circuit 18 of the second controlling circuit 12a is triggered by a leading edge part of the first control signal inverted by an inversion circuit 17a, and forms a pulse which is continued until before tau2 time of the first inverted control signal which comes in the next time. A delaying circuit 19 is triggered by a trailing edge part of the first control signal, forms a pulse which is continued for tau2 time, and supplies it to a muting circuit 12.

Title: Production of glass rods for optical fibers
Inventor: IZAWA TATSUO
IPC: C03B37/014
Filed: 1977-09-16
Abstract: PURPOSE:To faciliteate local heating and let sintering of the soot inside be readily progressed through reaching of laser light to the soot inside by using a laser light as a heat surce and applying strip-form lase light over the entire outside cirumference of the soot with an optical system. CONSTITUTION:The axis 6 of the laser light 2 emitted from a laser oscillator 1 and the axis of a soot form glass rod 5 are sligned and the optical axis 7 of a lens 3 is parallel with the optical axis 6 but is not in aliqnment thereto. As the lens 3 is rotated about the optical axis 6, creates the luminous flux 9 of ring form 8 of its section and this is reflected by an annular concave mirror 4 and is radiated in strip form on the outside circumferential part of the soot form glass rod. Here, the beam is made to parallel light by the reflecting mirror 4 and is made to such a radiation area at which the soot surface becomes temperature sufficient for sintering when converted from the output of the laser oscillator. Hence, sintering initites from the outside circumference part, but the sintered portion becomes transparent glass body and therefore the laser light gradually reaches the soot inside, thus enabling the sintering to be progressed.

Title: Segment assembling device with slide scaffolding
Inventor: HIRASAWA HIROYASU
IPC: E04G1/15
Filed: 1995-05-10
Abstract: PURPOSE: To improve workability by a method wherein a slide deck comprising a fixing frame, a moving table, and a moving table driving device is mounted on a working deck for assembling segments installed in the rear of a shield machine. CONSTITUTION: A worker steps on a working deck 11 and segments are assembled, in order, on the inner surface of an excavated tunnel. When there is a need for a work on a tunnel wall surface spaced away from the deck 11, a drive device 16 is operated, a moving table 17 is slid toward fixing frame 13 along a tunnel wall surface and the moving table 17 is extended from the deck 11. The worker is then transferred to the moving table 17 to effect a necessary work. Further, after completion of the work, the moving table 17 is slid over the fixing frame 13 and returned to a retraction position. This constitution performs easy and safe execution of a work in a position spaced away from a segment assembling device without moving the segment assembling device.

Title: Counting device
Inventor: MATSUZAWA YASUO
IPC: H03K23/66
Filed: 1981-07-20
Abstract: PURPOSE:To ensure precise time control with no error, by initially setting a dividing circuit in response to the data writing signal of a counting circuit of a microprocessor. CONSTITUTION:A lead 20 is connected to a clear terminal 22 of a prescaler 14. The digital value is written into a counter 16 through a data bus 18 and stored there. Then the prescaler 14 is initially set at a prescribed value as soon as a writing signal emerges at the lead 20. As a result, an acurate correspondence is always obtained between the time during which the counter 16 receives the wriring signal at the lead 20 from a control circuit and then produces an output signal to a lead 24 and the value which is written into the bus 18 from the counter 16. In such a way, no variance is caused in time control.

The ferromagnetic resistor elements 4 are arranged on the magnetic poles 4 at a minute interval in opposing locations. When the rotary shaft 2 is rotated in the direction of the arrow and the magnetic pole 3 is stopped below the magnetic resistor element 4, the position of the magnetic pole is read out, and the rotary angle and the rotary speed of the magnetic medium 2 are measured. Therefore the detected output can be read even in the static magnetic field in the simple structure.

Abstract: PURPOSE:To make loading, mixing and discharge of a load easily performable, by installing plural floor boards to open or close toward a lower part at the center side, a floor board supporting member tightly attached to a rear body, and a floor board on-off position regulating mechanism regulating an on-off position of each floor board each separately. CONSTITUTION:When ready-mixed concrete loaded on a rear body 2 is kneaded, coupling of a hinge 3a at the left is released, while an actuator 16a is extended longer and the rear body 2 is tilted to the right. At this time, a floor board 8b is going to open wider in proportion as the rear body 2 is being tilted because an actuator 16b is not extended, whereby volume at the right side of the rear body 2 becomes increased. Accordingly, the ready-mixed concrete slipped down on a surface of a floor board 8a is collected on the floor board 8b, therefore the concrete is kneaded by movement in this while. Afterward, when the ready-mixed concrete is discharge out, these two actuators 16a and 16b are extended longer at the same time, having the rear body 2 tilted to the rear, and the concrete is discharged by way of a chute 5.

Abstract: PURPOSE:To increase the rising speed of an AGC and to quicken and shorten the synchronization time to a reception signal by implementing the AGC over an entire frame without limiting the period for the AGC when the frame synchronization is not established. CONSTITUTION:A reception timing signal generating circuit 8 implements frame synchronization according to received synchronization word detection information and generates an AGC gate signal corresponding to the frame synchronization and gives it and a sampling signal to a level detector 9. In this case, the gate signal is always at an H level for a period when no frame synchronization is established at the time of the rise of the AGC circuit and when the frame synchronization is established, the gate signal is set to an H level only for the reception period of the prescribed pattern in the frame. That is, the detector 9 is operated in response to the gate signal fed from the circuit 8 and conversion is implemented only for a period when the gate signal is at an H level, a digital value is latched for the L level period and the signal is imparted to a variable attenuator 4 to control the attenuation.

Filed: 1980-08-20
Abstract: PURPOSE:To prevent breakdown of an FET by making the n layer of a pnp junction equal in the carrier concentration to the source layer of MESFET near which a pnp junction region is provided. CONSTITUTION:Si ion is selectively implanted into a channel region 4 employing a resist mask on a half-insulating substrate 1 doped with Cr. Subsequently, with a resist mask applied again, Si ion is implanted into a source 2, a drain 3 and the region 5 at a high concentration. Then, with a resist mask, Mg ion implanted to make p layers 61 and 62. The resist mask is removed and after an annealing in an As atmosphere, ohmic electrodes 7, 9, 101 and 102 and a gate electrode 8 on the channel are attached. When a connection is made as specified, the junction region 656 yields before the breakdown of the Schottkey junction thereby preventing the breakdown of the FET. This enables simultaneous formation an N layer 5 of the junction region 656 with the source thereby simplifying the production process.
