Title: Video pickup device
Inventor: NAKAYAMA YOSHIAKI
IPC: H04N5/232
Filed: 1988-04-14
Abstract: PURPOSE:To surely enable operation by providing a reception section receiving a command sent from a remote controller in a radio signal to a motor-driven universal head and a video camera. CONSTITUTION:When the remote controller 40 and a photodetection section 51 are opposed to each other, that is, when the operator itself is desired to be picked up, an infrared-ray indicating the operation command A is received by the photodetection section 51. Moreover, when the remote controller 40 and the photodetection section 50 are opposed to each other, that is, an object except the operator is desired to be picked up, the infrared-ray indicating the operation command A is received by the photodetection section 50 surely. In this case, the switching is executed in preceding over the pickup so that the operation signal A sent from the photodetection section 50 at least is given to a microcomputer 26. Thus, even when the direction of the video camera 30 is changed and even if the position of the remote controller 40 is deviated with respect to the motor-driven universal head 20, the infrared-ray is surely received and the operation of the motor-driven universal head 20 is ensured.

Title: Manufacture of compound semiconductor device
Inventor: ISHIKAWA YASUMASA
IPC: H01L21/308
Filed: 1990-04-04
Abstract: PURPOSE:To enable etching without generating unevenness on the surface of a compound semiconductor substrate containing As in the composition, by etching an Mo layer by using a hydrogen peroxide solution as an etching liquid. CONSTITUTION:A multilayer electrode 2 is formed on a GaAs substrate 1, and said electrode 2 is selectively etched by using resist 6 as a mask. Firstly an Al/Au layer 5 is etched by using the usual etching liquid. Then an Mo layer 4 is etched by using a hydrogen peroxide solution as the etching liquid. The etching rate of hydrogen peroxide solution is large to the Mo layer 4, and small to the GaAs substrate 1 and an Au layer 3. Hence, when the hydrogen peroxide solution permeates into the GaAs substrate 1 side through pin holes and step-difference parts of the substratum Au layer 3, unevenness are not generated on the surface of the GaAs substrate 1, and an almost flat state can be maintained.

Abstract: PURPOSE:To obtain a semiconductor integrated circuit having high integration degree and low power consumption equal to those of a dynamic circuit by providing a clock generating circuit generating a signal processing operation start clock with a detection signal from a detection circuit and an insulation gate field effect transistor (TR) supplying a charge to a required circuit node by the clock. CONSTITUTION:A detection circuit detects a change in at least one signal among input signals to the said circuit and gives a detection signal to a clock generating circuit 2. Then the clock generating circuit generates a signal processing start clock phi, which is given to each section of a signal processing circuit 3 provided with an MOST at the same time. On the other hand, the signal processing circuit 3 holds the preceding state until the input is changed and brought into the standby state through the input change. The circuit 3 is brought into the active static state with the impression of the clock phi and starts the signal processing operation. When the phi is turned off, the circuit is brought into the active dynamic state, completes a series of signal processings by outputting signals Y1-Yn and reaches the holding state. Since it is not required to supply a charge at all times to each circuit node in the circuits, high integration is attained.

Title: Feed screw device
Inventor: SAKAI MASAHIKO
IPC: F16H25/20
Filed: 1992-04-10
Abstract: PURPOSE:To provide a feed screw device capable of achieving high mechanical efficiency and feeding a screw silently with a large lead. CONSTITUTION:When a screw shaft 1 is driven and rotated, a taper roller 2 freely rotatably supported to a block 3 is put in rectilinear motion, i.e., fed by operation of a screw shaft 1 in which the shaft l turns along a screw 10. When the block 3 is driven and rotated, the screw shaft 1 is fed in the direction of its axis by operation of the taper roller 2 and a screw 10. The outer peripheral surface portion of the small diameter side of the tapered face 2a of the taper roller 2 makes contact with the valley portion side of the thread face of the screw shaft (i.e., the small diameter side of the thread face), and the outer peripheral surface portion of the large diameter side of the tapered face 2a makes contact with the top portion side of the thread face of the screw shaft (i.e., the large diameter side of the thread face), so slipping between the screw 10 and the taper roller 2 during rotation is reduced by a large amount. Further, minimizing of the slipping can be realized by selecting the dimension of each part to an optimal one.

Title: Operation of solid electrolyte fuel cell
Inventor: NISHIURA MASANORI
IPC: H01M8/04
Filed: 1992-04-13
Abstract: PURPOSE:To increase utilization efficiency of fuel, and eliminate danger by exhaust gas by mixing inactive gas into fuel gas to be supplied. CONSTITUTION:Fuel gas H2 mixed with inactive gas N2 is supplied to a fuel layer 3 of a power generation furnace 4. The quantity of the fuel gas H2 is thus decreased by the quantity of the inactive gas N2 mixed, so a ratio of H2 of fuel gas to react to the quantity of the supplied fuel gas H2 is increased. Utilization efficiency of the fuel gas H2 can thus be increased, and running cost can be decreased. Because concentration of residual fuel gas H2 in exhaust gas is also decreased, danger by the exhaust gas can be eliminated.

Abstract: PURPOSE: To provide grinding wheel dressing (regenerative) during grinding work by forming an electrophoretic type in-process dressing grinding wheel with conductivity and elasticity out of an abrasive grain and a conductive resin matrix. CONSTITUTION: A grinding wheel 10 used for grinding a prescribed work to be ground by an electrophoretic method has a circular grinding surface at one side, and is formed with a plurality of grinding surfaces apart from each other in the peripheral direction, at prescribed angular intervals from the center of the circle.

During grinding work, by making the grinding wheel 10 face a work 30 held in grinding fluid 38 where abrasive grains charged with negative potential are dispersed with the grinding wheel 10 serving as an electrode and positive potential applied, abrasive grains charged with negative potential are attracted to the grinding wheel 10.  It is thus possible to dress the grinding surface of the grinding wheel with the abrasive grains in addition to grinding work.
