Title: Speed control device for pipe forming mill
Inventor: MORIYASU TAMOTSU
IPC: B21D51/02
Filed: 1985-05-01
Abstract: PURPOSE:To eliminate a slip between a pipe stock and a roller by comparing current values of a driving motor before and after an end of the pipe stock passed a forming stand bites to the next forming stand, and thereby setting up a rotational speed of the driving motor. CONSTITUTION:Until an end of a material 3 to be worked is bitten by the second forming stand 11, current values of a driving motor 4 detected by a current detector 8 of the first forming stand 10 is memorized by a speed control unit 6. As soon as a detector 9 detects the biting of the stand 11 the control unit 6 compares current values before and after the biting and by changing the speed of the driving motor 4 of the stand 11, controls current values of the motor 4 of the stand 10 so that they return to the previous value before the biting. The similar control operation is repeated on the third forming stand 12 so as to make a condition not sustaining effects of biting for each stand. In consequence, the speed control unit for the pipe forming mill capable of eliminating the slip between the material to be worked and the roller is obtained.

Filed: 1987-04-15
Abstract: PURPOSE:To satisfactorily take the interchangeability of a '0' index and a coding index by recording in an index section an index signal for specific use and at least one block of coding index data. CONSTITUTION:A part of an information track generated as an oblique track being a part in which an information signal is not recorded by a rotary head is set to the index section 242, and head index information, for example, in which '1' or '0' continues and coded index data can be effectively recorded in the index section. Namely, all coded index data CDIX for six blocks are not all recorded in the index section, but at least one block BLK1 is set to be recorded and the rest to be used as the section for '0' index. Thus, '0' data in which the number of bits more than a threshold value in a '0' index detection circuit can continuously be recorded, and the interchangeability of the '0' index and the coded index can be taken.

IPC: F04B49/00
Filed: 1986-04-22
Abstract: PURPOSE:To improve responsiveness and precision by controlling the discharge flow rate by using the first proportional control valve having a proportional solenoid which operates in proportion to the electric current value. CONSTITUTION:The discharge flow rate is controlled by installing a pressure control valve 40 controlled by the first proportional control valve 20 having a proportional solenoid 21 and the second proportional control valve 30 having a proportional solenoid 31 into the control passage 24 for a pump 1. Therefore, the need of using a throttle valve besides a solenoid valve as in the conventional is avoided, and since the opening quantity to a pressure line 26 of the control passage 24 which is controlled by the first proportional control valve 20 can be controlled by a flow rate instruction device 51, responsiveness and precision can be improved.

Title: Image pickup device
Inventor: NAKAGAWA HIMIO
IPC: H04N5/225
Filed: 1984-05-11
Abstract: PURPOSE:To obtain picture quality with high definition by selecting the thickness of a crystal plate so as to make a trap frequency larger than 1/2 and smaller than 3/4 of the vertical space frequency of the scanning line in the sequential scanning system. CONSTITUTION:The light through the lens system 1 is separated (2), decomposed into R, G, B three colors, the vertical space frequency is filtered by crystal filters 3-5 having a stop band between 1/2 and 3/4 of the space frequency of the scanning line. The light incident at a right angle is decomposed into two lights apart by DELTAd=dtantheta at the opposite side, where theta is the angle of double refraction of the incident light and (d) is the thickness. The vertical space frequency by the synthesis of two lights is expressed in the equation. Thus, in selecting the thickness (d) satisfying the relation of 2/3DELTAl<DELTAd<DELTAl, where DELTAl is the interval of the scanning line of the image pickup face of photoelectric converters 6-8, the reflection of the light is reduced. As a result, since the beam diameter is stopped to the degree that no flicker is caused, the horizontal resolution is improved.

By such a pin arrangement, Karman's vortex street develops from the trailing stream of the first pin 4a. The temperature boundary layer is broken up at every pin 4a, and the heat transfer performance is directly controlled by the pin diameter. As a result, a high heat transfer performance can be obtained.

Title: Receptacle type contact and manufacture thereof
Inventor: JIYOSEFU REI GUTSUDOMAN
IPC: H01R43/00
Filed: 1990-04-10
Abstract: PURPOSE:To secure sufficient contact by providing a plurality of both end fixing conductor pieces and one end fixing conductor pieces alternately along the outer circumference of an inner cylindrical body. CONSTITUTION:A both end fixing conductor piece 14 is comparatively high in stiffness but low in elasticity against pressing force in the radial direction because its both ends are fixed to cylindrical sections 12a and 12b. This thereby permits a pin which is inserted in, to be effectively guided along its plane surface so that a contact 10 is improved in its prizing resistant characteristic. A contact conductor piece 15 makes contact with the inserted pin with sufficiently high elasticity because it is fixed at one end but is freely slidable at the other end. Sufficient contact pressure to the inserted pin can thereby be provided by the use of both of the conductor pieces 14 and 15.

Title: Cleaning zone, cleaning device and method for cleaning sewage
Inventor: UEKI KYOKO
IPC: C02F3/04
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To exhibit a high sewage cleaning property by consisting of the cleaning device of columnar perforated columnar bodies and introducing water sheets of a porous structure connecting these perforated columnar bodies to each other and forming constricted parts to expose dropping water to air to the air between the perforated columnar bodies. SOLUTION: The sewage to be cleaned is supplied to sewage sprinkling means 4 from a supply pipe 52 from outside which is a sewage supplying means 5 disposed above a tank 2. When the prescribed volume of the sewage accumulates, the sewage leaks from the sits formed at the flanks of a vessel and flows down evenly over the entire width of a cleaning zone 3 disposed to face downward in the lateral parts of the sewage sprinkling means 4. The sewage flows down between the plural perforated columnar bodies disposed successively in the perpendicular direction of the introducing water sheets. At this time, the sewage flows down slowly while successively creeping along the respective perforated columnar bodies and, therefore, the sewage is successively decomposed and purified by the microorganism deposited on the performed columnar bodies.  As this time, the fresh air is forcibly or naturally fed into the tank by an air supplying means 6, by which the effect of decomposing and cleaning the sewage by the microorganisms is made be made more vigorous.

Title: Failure sensing method in pumping yard
Inventor: UMEZAWA SOHEI
IPC: F04B49/10
Filed: 1993-04-20
Abstract: PURPOSE:To certainly and accurately sense a failure in different object to be sensed using a comparatively simple comfiguration by judging if any failure exists from the change the white or black level area ratio in the current image to the one a certain time before. CONSTITUTION:The image output from a CCD camera photographing a certain place in a pumping yard is fed to a frame memory, at Step 31. Then a CPU conducts a light/dark histogram processing, at Step 32. The number of white level or black level fragments of the image split into a plurality of fragments is calculated as the area, at Step 35. When for example the black level of the image calculated as the current value is stored in the memory, the CPU compares it with the calculated value of the previous number of black level fragments, at Step 38, and failure judging takes place upon existence or not of any change from the previous value. That is, failure existence is judged from the area ratio of the black level. This eliminates necessity for provision of failure sensing device for each different object to be failure sensed.

In the structure, the rise of a dislocation 5 generated at the interface of GaAs/Si in the part of the seed is stopped by the second SiO2 film 3. As a result, the dislocation is not passed up to the surface of the GaAs growth layer 4.
