Title: Method and device for measuring voltage of high resistance semiconductor
Inventor: NISHIMOTO NAOAKI
IPC: G01R31/26
Filed: 1987-03-30
Abstract: PURPOSE:To shorten a resistance measurement time by providing two gate circuits which estimate a saturation voltage from the variation rate of an induced voltage and sampling the induced voltage. CONSTITUTION:When a DC current I is supplied between terminals A and B of a semiconductor sample 2, a detection output induced between terminals C and D appears across a resistance 4. Then a gate 5 is opened at time t1 and a gate 6 is opened at time t2; and a differential amplifier 7 calculates the difference between the both and the gates 5 and 6 are opened at time t3 and t4 respectively, so that an arithmetic circuit 8 calculates a variation rate and a saturation voltage at two points from the output difference. Thus, the resistance measurement of the sample 2 is executed in a short period of time and many samples are measured in a short period of time. In this case, the time interval between the opening of the gate 5 and the opening of the gate 6 is made variable to select proper sampling intervals for various waveforms.

IPC: H03M7/40
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To decide the selection index of a coding parameter applied to the occurrence probability with higher accuracy and smaller arithmetic load by setting the probability threshold serving as a sorting boundary of the probability section, corresponding to an index in the arrangement of bits that can be decided with small arithmetic load and selecting a prescribed index corresponding to the estimated occurrence probability, without having to divide it from the probability section that is sectioned by the probability threshold. SOLUTION: A symbol decision means 10 refers to the estimated value stored in an estimated value storage means for deciding whether the inputted coding data have a superior symbol MPS or a inferior symbol LPS. Then a probability estimation means 12 refers to the LPS count value and the symbol count value to select one of plural prepared key probability values. Based on the key probability value selected by the means 12, the MPS or LPS that is decided by the means 10 is coded by a coding means 13. When this coding is finished, a symbol coefficient means 11 updates the LPS counted value.

Abstract: PURPOSE:To improve the maneuverability of a camera lens by receding an extender optical system into a lens grip and sharing a receding/storing part with the lens grip at the receding of the optical system to a position located on the outside of a photographing optical system. CONSTITUTION:At the receding of the extender optical system 4 to the position 5b located on the outside of the photographing optical system, the optical system 4 is receded into the expanded part 2a of the lens grip 2.

Title: Semiconductor device
Inventor: MACHIDA KAZUMICHI
IPC: H01L21/60
Filed: 1985-04-11
Abstract: PURPOSE:To make it possible to lower the cost without impairing reliability for a long time, by using a piece of silver wire having the purity of 99.9% as a thin metal wire, and using a thin gold film as an electrode on a semiconductor chip. CONSTITUTION:A piece of silver wire 6 having the purity of 99.9% is used as a thin metal wire. When the wire is bonded to an aluminum electrode, abnormal diffusion occurs between the aluminum electrode and the silver wire 6, and a fragile diffused layer having a high resistance is formed at an early stage. Therefore, gold, which has less diffusing property with the silver, is used as the electrode. Thus the problem of deterioration of reliability for a long period due to the fragile diffused layer having the high electric resistance is solved. When the gold is used as the electrode, the amount of the use of the gold is less in comparison with the case the gold is used for wire.

IPC: G01R31/28
Filed: 1991-04-11
Abstract: PURPOSE:To observe high speed operation and the connecting state of input signals directly by otherwise providing a testing circuit. CONSTITUTION:A buffer amplifier 1 distributes input signals into an internal circuit 4 and a signal switching circuit 2. The signal switching circuit 2 receives the control signal through a signal terminal 5 and performs switching for selection of a parallel input signal from an input signal terminal 7 or the output of a scanning F/F 3 as series input. The scanning F/F 3 latches the input signal in parallel based on the signal from a clock signal terminal 6 when the parallel input operation is selected. Then, the operation is further switched to the series input operation, and the signal is outputted through an output signal terminal 8 at every one cycle of the clock signal terminal 6. Meanwhile, a buffer amplifier 11 distributes input signals into an internal circuit 12 and a parity generating circuit 15. The generated parity signal is outputted through an output terminal 14.

Filed: 1987-03-31
Abstract: PURPOSE:To eliminate an error in distance measurement due to pitching of a feed table by a method wherein a beam from a light source for correction is applied to a photoelectric transfer element through a photosensing mirror, the inclination of said mirror is detected and an angle in distance calculation is thereby corrected. CONSTITUTION:A pulse impressed from a timing signal generating circuit 67 on a light source 11 for measurement and sample hold circuits 53 and 55 are reverse in phase to a pulse impressed therefrom on a light source 22 for correction and sample hold circuits 54 and 56. Accordingly, a signal from a photoelectric transfer element 4 is amplified to generate a waveform wherein a measuring light and a correction light appear alternately. This signal is passed through the circuits 53 and 54, or 55 and 56, and it is separated thereby into the measuring light and the correction light. In the case when the pitching of a feed table 20 exists continuously, an output of a subtracter 63 is read by a computer 80. Then, an inclination DELTAbeta of a wavelength selecting mirror 21 is determined from the relationship between a predetermined output of the subtracter 63 and the inclination DELTAbeta, and an inclination alpha of a mirror can be corrected by a formula I. IN the formula I, R denotes a distance from a reference axis to an object of measurement, and L a distance to a mirror 21.

Abstract: PURPOSE:To obtain a circuit for inhibiting the rewriting of an EEPROM, by connecting in series an output of a sense circuit which is connected to an EE memory cell transistor, to two NOR circuits, and using its NOR output as a rewriting signal.
