Patent JP-S6239087-A (JP)
Title: Semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/00
Filed: 1985-08-14
Abstract: PURPOSE:To provide the functions of both the reading light source having low noise characteristic and the optical writing light source capable of large light output oscillation by specifying the ratio of differential gain coefficients in an active region and a depletion layer region and the ratio of carrier natural lifetime in those regions. CONSTITUTION:On an N-type GaAs substrate 10, an N-type Al0.45Ga0.55As cladding layer 11, an N-type Al0.15Ga0.85As active layer 12, and an N-type Al0.45Ga0.55As clad ding layer 13 are grown and a high-concentration Zn diffusion region 15 and a low- concentration Zn diffusion region 18 are formed. In the N-type active layer 12, an active region 20 where Zn is diffused at low concentration is formed. When a reverse bias is not applied to the region 15, the large light output oscillation needed for optical writing is generated. When a depletion layer is expanded to the active layer by apply ing a reverse bias, self-oscillation is produced in the active region 20 and the residual noise can be reduced. When the ratio of the lengths of the active region and the depletion region is (1-h):h and a loss of the depletion region is beta, the relation of the ratio g1/g2 of differential gain coefficients in the active region and the depletion region and the ratio tau1/tau2 of carrier natural lifetime of those regions is expressed by: tau1/tau2 g1/g2 > -beta/1-beta and tau1/tau2 > 1/1-h mu (1-beta/-beta) g1/g2 + 1.

Title: Semiconductor relay
Inventor: NAKAYA MINORU
IPC: H03K17/78
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent a MOSFET from being conductive in its off-state even when a signal with a high voltage and a high slewing rate is applied by detecting a gate current flowing from a drain of the MOSFET to its gate so as to short-circuit the gate and the source. SOLUTION: When a voltage VD applied to a drain of a MOSFET 3 changes, a surge current flows to a drain, a capacitor 71 and a resistor 72 from the drain of the FET 3 via an internal capacitance CDG. When a node voltage VA and a gate voltage VG rise and reach a voltage, a TR 73 becomes conductive to short-circuit the gate and the source of the FETs 3, 4. Thus, the surge current flows between the gate and source of the FET 3 via the TR 73 to prevent the voltage VG from reaching a threshold voltage. Thus, the FETs 3, 4 in the off-state are not conductive even with application of a signal with a high voltage and a high slewing rate, and no large capacitance capacitor is required for a surge detection absorbing circuit 7, which is integrated in a semiconductor chip in a very small size.

IPC: G07G1/12
Filed: 1992-07-08
Abstract: PURPOSE:To provide an electronic cash register which can rapidly and easily set and register a text such as an article name. CONSTITUTION:A single word consisting of previously specified plural characters and a character code corresponding to the character are stored in a conversion file 6 set to a random access memory 4. At the time of inputting the character code through the use of a key input means 7, CPU 2 reads the single word corresponding to the inputted character code from the conversion file 6 so as to set and register the single word to a PLU(price lookup) file 5. Consequently, as the spelling of the single word to set-register is not needed to input one character by one character, the single word is not in danger of being erroneously inputted and is rapidly and easily set and registered.
