IPC: H03F3/345
Filed: 1992-11-26
Abstract: PURPOSE:To eliminate the effect of the base current of a transistor TR to the compensation for the base current of a current mirror by reducing the base current. CONSTITUTION:The emitters of the 1st and 2nd PNP TRs 1 and 2 are connected to a high potential power supply 5, and the bases of both TRs 1 and 2 are connected to the drain of an N-channel MOS FET 4. Then the collector of the TR 1, the gate of a TR 4, and an input terminal 11 are connected to the high potential side of a constant voltage source 6. The low potential side of the source 6 and the source of the TR 4 are connected to a low potential power supply 10. Then the collector of the TR 2 is connected to an output terminal 7. Under such conditions, no current flows to the gate of the TR 4. Thus the conventional current difference that is caused when the electrical characteristics are equal to each other between both TRs 1 and 2 is substantially set at zero.

Title: Radio communication equipment
Inventor: TANABE TAKAYUKI
IPC: H04B7/005
Filed: 1989-12-05
Abstract: PURPOSE:To prevent power from being consumed unnecessarily by controlling transmission power by deciding successively the received result of a receiving means. CONSTITUTION:A CPU block 10 instructs a transmission output level to a transmission output control part 2 through a line 6 in order to obtain the lowest transmission level capable of communication, and subsequently, it sends test data to a transmission part 4 through a transmission data line 7, and emits a radio wave from an antenna 1. On the other hand, when an opposite party side receives normally the test data, it returns the test data back, and the CPU block 10 receives it to a reception part 5 through the antenna 1, and decides it to be normal reception, and next, it repeats this work by lowering the transmission level. Besides, when the test data is not normally received, namely, in the case the CPU block 10 can not receive the returned data, it decides it to be a transmission error, and instructs the transmission level higher than preceding one again to the transmission output control part 2 and executes similar work, and repeats this work until the reception becomes available. Thus, the power consumption can be saved.

Filed: 1989-12-06
Abstract: PURPOSE:To discriminate whether an object in a background is moving or the background itself is moving by providing a 2nd photodetector layer where sets of plural photodetectors sending a light from a lighting layer emitted corresponding to an output from a moving sensing means are arranged in 2-dimension. CONSTITUTION:The unit is provided with an image forming lens 41, a 1st photodetector layer 42, a 1st differential output generating layer 43, and a moving sensing layer 44, and a 2nd photodetector layer 45 is arranged opposite to light emitting elements 46 arranged in 2-dimension and photodetector array 50 is arranged to the 2nd photodetector layer 45 in 2-dimension. In this case, the light emitting elements 46 of the light emitting layer are lighted corresponding to the output of a moving sensing means 44 and the lighting is sensed by center photodetectors 47 and peripheral photodetectors 48 of the 2nd photodetector layer 45. Then a 2nd differential output generating element 80 receives an output from the center photodetector 47 and an output from the peripheral photodetector 48 to generate an output equal to a function of weight sum of reception inputs. Thus, whether an object is moving in a background or the background itself is moving is discriminated.

Title: Cmos analog switch for input/output switching
Inventor: KASHIMOTO KOJI
IPC: H03K19/00
Filed: 1987-12-14
Abstract: PURPOSE:To prevent a leak current from flowing even when a voltage is impressed to an input/output terminal at the time of a power source time-off by composing a CMOS analog switch of a level shift transistor and an Nch-MOS transistor. CONSTITUTION:Without using a Pch-MOS transistor, a switch 10 is formed only of an Nch-MOS transistor 6 by lowering potential transmitted with the switch by means of the level shift transistor. At the time of using an input/ output terminal 4 as an input terminal, when a switch control terminal 3 is made into the same potential as a power source 9, the Nch-MOS analog switch 10 is turned on, and the input/output terminal 4 functions as the input terminal. Here, by turning on only the Nch-MOS analog switch 10 after the potential is lowered by a level shift transistor 7, the potential can be transmitted only by the Nch-MOS transistor 6. Even when the power source 9 is turned off, even at the time of impressing the voltage to the input/output terminal 4, an impedance is made high, and the leak current is not made to flow.

Title: Speed change device
Inventor: TATENO MASAO
IPC: F16H9/18
Filed: 1991-12-02
Abstract: PURPOSE:To improve the speed characteristic of a driven shaft by making a driven side movable pulley approach a driven side fixed pulley by liquid pressure introduced into a control cylinder by centrifugal force and providing a flow limiting means 10 a piping between an oil reservoir in the case of an auxiliary machinery and the control cylinder. CONSTITUTION:When rotating speed of a drive side pulley and a driven side pulley 3 exceeds a speed change point (specified speed), oil is sucked into a control cylinder 19 from an oil reservoir in a case 45 in accordance with capacity increase of the control cylinder 19, the amount of oil in the control cylinder 19 increases in accordance with rise of the rotating speed to generate sufficient centrifugal pressure, and movement of a fixed pulley piece 9 in the diameter in-creasing direction is expedited by liquid pressure in the shaft direction by the centrifugal pressure. Consequently, rise of the rotating speed of the driven side pulley 3 following the rotating speed of the drive side pulley comes to be slight and it comes to be roughly constant speed over an extensive speed territory. The oil suction amount into the control cylinder 19 from the oil reservoir in the case 45 is limited by a flow limiting means 51, and accordingly, the speed change point comes to be high enough.

Title: Semiconductor device and two-layer lead frame used for it
Inventor: HOTTA YUJI
IPC: H01L23/50
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a lead frame for semiconductor device having such a structure that does not allow the occurrence of die shifts and voids when a semiconductor device is sealed with a resin even when the thickness of the lead frame is reduced to 0.8mm and, therefore, can improve the reliability and productivity of the semiconductor device. SOLUTION: In a two-layer lead frame in which a lead section is laminated upon a metallic layer 12, the thickness of an adhesive layer 13 which is used for fixing a semiconductor device 2 to the metallic layer 12 is adjusted to 100-350μm so that the device 2 can be buried in the adhesive layer 13 by 1/3 or more in thickness. Therefore, the occurrence of die shifts and voids can be suppressed, because the degree of irregularities in a resin sealing area can be suppressed.
