Title: Operation instruction receiving circuit for video tape recorder
Inventor: SAKURAI HIROFUMI
IPC: H04N5/782
Filed: 1987-07-16
Abstract: PURPOSE:To reduce wiring for an operation instruction signal by converting signals with different periods respectively into digital signals '0' and '1'. CONSTITUTION:A converting operation instruction signal 1 is outputted as a digital signal '1' when the period of a waveform inputted within a fixed time T is one period, and when the period is 1.5 periods, outputted as '0'. A waveform obtained by delaying the signal 1 by time T through a delay circuit 3 and the waveform of the signal 1 itself are inputted to an EXOR 4, its output waveform is amplified by an amplifier 6, its high frequency component is removed through a low-pass filter, and the signal 1 is reversely converted into digital signals '0', '1' by a comparator 8. The output waveform of the comparator 8 is read in a shift register 10 to obtain an operation instruction output 11. Consequently, only one operation instruction signal can be obtained, so that the number of terminals of a semiconductor integrated device can be reduced and the number of wires for the operation instruction signal can be also reduced.

Title: Exciting light source driving system for optical amplifier
Inventor: GOTO KOJI
IPC: H04B10/079
Filed: 1990-07-05
Abstract: PURPOSE:To increase the life of an exciting light source and to improve reliability by providing comparing control means, and controlling the output of the source so that an output signal power or combined power of the sources becomes a predetermined level. CONSTITUTION:Part of a signal light of output signals amplified upon propagating in a rare earth element-doped optical fiber 2 is branched by an optical branching filter 20, and input to a comparing controller 30. A signal power level is detected through a photodetector 21, an amplifier 22 and a low pass filter 23, and compared with a predetermined power level output from a reference voltage generator 25 by a comparator 24. In this case, if it is lower than the reference voltage, injecting currents from drivers 9a, 9b are increased, while if it is higher than the reference voltage, the currents from the drivers 9a, 9b are decreased. Thus, the light output of an exciting light source is controlled and makes the signal power level optically amplified at the output of the filter 20 constant. Thus, the life of the source is increased, and reliability can be improved.

Title: Suction device
Inventor: ARIE MAKOTO
IPC: B25B11/00
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To enable a suction device to stably hold an object to be sucked by forming a negative pressure hole so that the opened area of the hole can become larger as going farther from a contact surface. SOLUTION: A suction device is provided with a sucking section 24 equipped with a contact surface 28 which comes into contact with an object 13 to be sucked and a negative pressure hole 29 which is opened on the surface 28 and supplies a negative pressure and holds the object 13 on the surface 28 by suction with the negative pressure from the hole 29. The hole 29 is formed so that its opened area can become larger as going farther from the surface 28. For example, the hole 29 is formed in a truncated cone which is widened toward the end from the opening 30 of the hole 29. Accordingly, the hole 29 is not blocked with foreign matters, such as silicon waste, etc., sucked into the hole 29 through the opening 30, because the foreign matters pass through the hole 29 after passing through the opening 30. Therefore, the object 12 can be held stably on the surface 28 of the suction section 24 by applying the negative pressure to the surface 38 from the hole 29, because the negative pressure does not become weaker, but is always maintained at an appropriate value.

Title: Manufacture of semiconductor element
Inventor: INABA KEIZO
IPC: H01L21/322
Filed: 1991-07-19
Abstract: PURPOSE:To enable the hFE value of a wafer cover even after the electrode formation step to be adjusted by a method wherein an impurity diffused layer after performing the electrode formation step of a semiconductor element irradi ated with corpuscular beams is heat-treated so as to be displaced. CONSTITUTION:Within a wafer 1 wherein a base region and an emitter region are formed while characteristics inspections through an electrode hole and after the formation of Al electrode are finished on one main surface of a semiconductor substrate, even the part near the junction part 6 of the emitter and base is irradiated with corpuscular beams 9. In such a state, the whole body is heat-treated at the temperature level not causing a damage to the Al electrode, i.e., at 400-600 deg.C. Next, the fluctuation amount of hFE value assessed by the later characteristics inspection step is controlled by changing the intensity of corpuscular beams, the temperature and time of the heat treatment. Through these procedures, the impurity atoms in the crystal structure can be brought into easily movable state by the corpuscular beams irradiated on the wafer after the formation of the Al electrode so as to accelerate the impurity diffusion by further performing the heat treatment step thereby making the fine adjustment of the hFE value after the electrode formation feasible.
