Title: Mos transistor with large gate area
Inventor: KURODA HIDEAKI
IPC: H01L21/8234
Filed: 1990-08-23
Abstract: PURPOSE:To sufficiently compensate the interfacial level between a gate oxide film and semiconductor substrate by H2 annealing by forming a plurality of divided MOS transistors in one area and constituting one MOS transistor by connecting the divided MOS transistors with each other in series or parallel. CONSTITUTION:A plurality of divided MOS transistors are provided in one transistor forming area and one MOS transistor is constituted by connecting the divided MOS transistors with each other in series or parallel. For example, the plurality of divided MOS transistors are formed in one body by connecting the divided MOS transistors in series and forming a gate electrode 5 to have a comb-like planar shape. Accordingly, the interfacial level between a gate oxide film and semiconductor substrate can be compensated sufficiently, since no part exists far from the side face of the gate electrode and hydrogen molecules (H2) reach everywhere of the boundary from the outside of the gate electrode when H2 annealing is made. Therefore, an MOS transistor having a large gate area can be prevented from becoming unstable in threshold voltage.

Title: Load detection device
Inventor: INOUE KOJI
IPC: G01L1/04
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce cost in an oscillation circuit by a constitution wherein a coil is excited by means of a rectangular wave excitation voltage and a hysteresis width is provided between an ON signal generation level and an OFF signal generation level of a comparator input. SOLUTION: A coil is excited by applying a rectangular wave signal having a frequency of which period is shorter than a required load response time from an oscillation circuit. At that time, a high frequency component of the rectangular wave is reduced by virtue of the minimum necessary operation of a filter so that the output signal becomes a shape similar to a triangle wave. Then, a hysteresis width is provided between an ON signal generation level and an OFF signal generation level of an input section of a comparator and is set to be equal to an amplitude of a frequency component of an output signal of the coil. While a detected signal instantly becomes a level equal to or lower than the ON level when the ON signal is outputted, the OFF level is set to be lowered by a level of the hysteresis width so that the ON signal is maintained to be outputted.  The OFF signal is outputted when fluctuation of voltage which is greater than the oscillation component is generated, thereby preventing a misoperation.

Title: Carrier wave reproduction circuit
Inventor: TAKEDA YUKIO
IPC: H04J11/00
Filed: 1983-11-30
Abstract: PURPOSE:To reproduce easily a carrier wave for synchronizing wave detection of a received multi-value QAM (quadrature amplitude modulation) signal at the reception side, by providing a phase control circuit which outputs the signal component produced by a leakage carrier wave contained in a synchronizing wave detection output signal of said QAM signal in the form of a phase control signal. CONSTITUTION:A received multivalue QAM signal is branched by a hydrid circuit 21 and applied to syncrhonizing wave detectors 22 and 23. The output signals fed from a voltage control oscillator 33 are supplied to those detectors 22 and 23 with 90 deg. phase to each other via a 90 deg. hybrid circuit 34. In other words, the QAM signal receives the synchronizing wave detection by using the output signal of the oscillator 33 as a reproduction carrier wave. Then a signal of a level corresponding to both the frequency and phase differences between a leakage carrier wave and a reproduction carrier wave appears to the multi-value data DQ of a channel Q of the output signal of the detector 23. A phase synchronizing circuit is designed so that the above-mentioned signal is set at zero, and the output signal phase, i.e., the reproduction carrier wave phase is controlled. Thus it is possible to obtain synchronization between the phase of the reproduction carrier wave and that of the leakage carrier wave.

Title: Silver halide color photographic sensitive material
Inventor: ICHIJIMA YASUSHI
IPC: G03C7/305
Filed: 1984-10-25
Abstract: PURPOSE:To improve graininess and sharpness b incorporating a coupler. CONSTITUTION:The coupler to be added is represented by the formula shown there in which A is a coupler residue to be cleft from X by reacting with the oxidation product of a color developing agent; X is 0 or S; R1 is an aliphatic, aromatic, or heterocyclic group; R2 is a substituent; n2 is 0, 1, or 2 and when n is 2, each of R2 may be different or combine with each other to form a divalent cyclic group. Such a coupler releases an aromatic alcohol or thiol substd. SO2NH2 or OH group upon the reaction with the oxidation product of a color developing agent, and this released compd. reduces said product by its own strong reducing power. The substitution of SO2NH2 or OH group properly enhances solubility and diffusitivity of the released compd. in an emulsion. The dimensions of the substituents R1. R2 can control the diffusivity, thus permitting the obtained photographic sensitive material to be prevented from mottles, enhanced in graininess, and improved in sharpness.

Inventor: GUNTERU DOREHERU
IPC: B60K23/00
Filed: 1982-12-21
Abstract: Method and device for controlling a motor vehicle power unit consisting of an internal combustion engine and a variable-ratio power divider transmission. For adjusting the output, use is made of the data from the only sensor sensing the speed at the transmission output end, and from the accelerator and brake pedals. The resultant reference value is directly transferred to an engine function generator in which engine characteristics are stored. The output signal from the engine function generator is used to control the throttle or the fuel supply system actuating lever. The reference generator also directly influences a speed function generator, in which the optimum speed is stored. Its output signal is linked with the indication from the sensor so as to form a reference value for the transmission ratio and is processed in a transmission control unit for form actuating signals for the transmission.
