Patent JP-H027554-A (JP)
Title: Input circuit of semiconductor device
Inventor: HORIKAWA SHIGEMITSU
IPC: H01L27/06
Filed: 1988-06-27
Abstract: PURPOSE:To obtain sufficient amount of static electricity withstand voltage effect against a negative surge voltage by separating channel stopper layers halfway and providing a conductive layer between the separate channel stopper layers through an insulation film. CONSTITUTION:An input terminal consisting of Al, etc., is formed on an N<->-type semiconductor substrate 11, it is connected to the terminal part of a P<+>-type diffusion layer 13, a channel stopper layer 15 consisting of an N<+>-type diffusion layer is formed around the P<+>-type diffusion layer 13, and it is separated nearly at the center and is placed being separated. Then, when a negative surge voltage is applied to and the surge charge passes to an input terminal 12 through a diode D2 which is inverse-biased by a power supply voltage terminal VDD, it instantaneously passes to the input terminal 12 through the power supply voltage terminal VDD, a resistor R4, and a capacitor C2. However, since the channel stopper layer 15 is cut off, resistance of the N-type semiconductor substrate 11 and that of the channel stopper layer 15 work in series, thus resulting in a great resistance and thus securely preventing insulation breakdown from taking place.

Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To quicken user mutual authentication between a client and a server in a client/server system through an internet or an intra-net. SOLUTION: In the first connection from a client 1 to a server 2, a public key of the opposite party is mutually used and a random number and common key information for authentication are encrypted and exchanged with each other to make mutual authentication and both parties decide which authentication random number and common key are used in succeeding communication. Furthermore, the random number and the common key for the authentication are stored in storage means 17, 27 of the client side and the server side. In the case of connection between the same client 1 and server 2 at and after the 2nd times, the random number for authentication having been stored is encrypted by using the common key and exchanged to mutually authenticate whether or not they are the same opposite parties.

Title: Adaptive difference pcm device
Inventor: MAKINO MASAYUKI
IPC: H04B14/06
Filed: 1983-08-30
Abstract: PURPOSE:To reduce quantizing noise and to improve quality of voice by making step width continuously variable in analog basing on amplitude information or frequency information extracted from a forecasting signal and making automatic adjusting to obtain an ideal step width in probability. CONSTITUTION:When an absolute value X14 of instantaneous amplitude obtained from a detecting circuit 14 is small, a step signal X2 obtained from a step signal generating circuit 2 is not attenuated by a transistor TR23 and after supplied to a multiplier circuit 3 as a signal X16 for gain determined by amplifiers 16, 17, multiplied to polarity information DATA2. As base current of the TR23 increases with increase of the value X14, and the signal X2 is attenuated according to magnitude of the value X14, the signal X16 becomes small. Thus, step width can be made variable continuously by the absolute value of instantaneous amplitude of a forecasting signal Sout2.

IPC: G01N21/00
Filed: 1982-09-10
Abstract: PURPOSE:To measure the pressure compression waves induced by an incident light source and to obtain a photoacoustic analysis device of high sensitivity for liquid by providing such an analytical cell of which the ratio r/r0 between the radius (r) on the inside peripheral surface of the analytical cell and the radius r0 of the incident ray is kept within a specific range. CONSTITUTION:A cylindrical piezoelectric conversion element 10 is disposed in the central part of an analytical cell, and an outlet and inlet 20, 22 for a liquid sample are mounted at both ends thereof. A laser beam 14 is made incident through one window 24B to the inside of the analytical cell packed therein with the liquid sample and emits from another window 24A. The dependency of the intensity of the photoacoustic signal on the radius (r) of the inside peripheral surface of the analytical cell is shown in the figure. The graph reveals that a large induced voltage is generated in the range of 1<=r/r0<=8. The operator is therefore simply required to adjust the radius of the inside peripheral surface of the analytical cell and the radius of the incident ray so as to be kept within said range.

Abstract: PURPOSE:To remove the influence of noises of light from a remote control signal input part during the output of an operation-side signal by performing preprocessing for masking a remote control reception signal when there is the operation-side output signal at a gate circuit. CONSTITUTION:If signals converted into electric signals are inputted to an AND gate 4 at the same time through an amplifier when a signal from a key operation part 1 and a signal or noise which is inputted after conversion from infrared rays into an electric signal by a remote control signal input part 3 are inputted, the output pulse signal of a one-shot circuit 2 is inputted to the AND gate 3 for one period when the one-shot circuit 2 outputs an operation signal from the operation part 1, so they are ANDed to cut off the signal from the remote control signal input part 3. Thus, the output signal of the remote control input part is masked by the AND gate 4 before the remote control reception signal and operation-side output signal are ORed by an OR gate 5 and inputted to a controller 6.
