IPC: F23D11/24
Filed: 1982-01-19
Abstract: PURPOSE:To remove temporary change, pulsation or deflection of air by providing a rectifying grid at an air sending part from a fan mechanism into an inner cylinder. CONSTITUTION:When power is supplied to a motor 17 to actuate a fan mechanism, combustion air is supplied through an air passage 20 into the inner cylinder 10. At this time, the temporary changes or pulsation of the amount or pressure of the supplied air are smoothed by the provision of the rectifying grid as a resistance, and deflection in the air flow caused by the shape of a part of the air sending passage are also removed. The combustion air, further removed with the deflection therefrom by restrictions to flowing resistance and flowing amount imparted by an inlet port of a divided cylinder 15, is supplied into the inner  cylinder 10. Then the combustion air is jetted from respective air injection holes  14 at a predetermined ratio into a premixture zone (b) and a combustion zone  (a) within a combustion chamber 6. By this, the flame maintenance is stable, an exhaustion of unburnt substance is suppressed, and also combustion noise can  be suppressed effectively.

Abstract: PURPOSE:To save a space by providing a counting rate calculating element which calculates a counting rate of this time on the basis of a pulse signal count value, a selecting element which compares the counting rates of this time and the last time with each other and selects the one meeting the condition, etc. CONSTITUTION:When radiation enters a pulse-type radiation detector 1, first, an output pulse corresponding to the strength of the radiation is outputted from this detector 1 and it is amplified by an amplifier circuit 2 and then inputted to a counter circuit 3. The circuit 3 conducts level discrimination at a level corresponding to a peak value of the output pulse supplied from the circuit 2 and filters noise, and then it counts the pulse and supplies a count value thereof to an arithmetic circuit 4. The circuit 4 collects the count value every time when it is supplied from the circuit 3, determining a counting rate of this time on the basis of the time passing from the supply of the count value of the last time to the supply of that of this time and the count value supplied this time and comparing it with the counting rate of the last time. Next, the circuit 4 determines a time constant by determining an increase or decrease of the counting rate, executes an operation to determine the counting rate to be outputted this time, and outputs it.

Abstract: PURPOSE:To obtain high external quantization efficiency and rapid responseness by reflecting incident light advanced in parallel with a substrate by the surface of a reflection mirror, receiving the reflected light by a concave mirror formed on the surface of the substrate, reflecting and converging the light by the concave mirror, and then extracting the light from the rear face of the substrate. CONSTITUTION:The optical semiconductor device is a device for extracting light made incident in parallel with the substrate from the direction vertical to the substrate and is constituted so that the incident light advanced in parallel with the substrate is reflected by the surface of the reflection mirror, received by the concave mirror formed on the surface of the substrate, reflected and converged by the concave mirror, and then extracted from the rear face of the substrate. For instance, light projected from the end face vertical to the substrate is reflected by the inclined face of the substrate 1, passed through a space surrounded by the concave mirror 11, reflected again by the mirror 11, and made incident upon the substrate 1 so as to be focused on the rear face of the substrate 1. Since light projected from a waveguide or a laser can be converged and extracted from the direction vertical to the substrate, high external quantization efficiency and rapid responseness can be obtained by photodetecting the light by a photodetecting element having a small photodetecting diameter or an optical fiber.

Title: Schottky type field effect transistor
Inventor: KONDOU MOTOKI
IPC: H01L29/08
Filed: 1983-01-20
Abstract: PURPOSE:To enable to improve the drain withstand voltage and prevent the current concentration at the end of a drain electrode by a method wherein a low resistant region immediately under a source electrode is made deeper than that immediately under the drain electrode, and the low resistant region immediately under the drain electrode is formed shallower than the depth of an active layer. CONSTITUTION:Since the deep low resistant layer 9 reaching a semiinsulation layer 1 across the active layer 2 exists in the region immediately under the source electrode 8, source-gate resistance reduces very much, and then the increase of output and high gain are obtained. Besides, the low resistant region 10 immediately under the drain electrode 14 is shallower than the active layer 2, therefore a depletion layer produced between the gate and drain at the time of impressing a gate bias voltage widely extends to under the shallow low resistant region 2. Accordingly, the drain withstand voltage increases and flows to the drain electrode 14 not only from the side surface of the low resistant region 10 under the drain electrode 14 but from the bottom surface, resulting in enabling to prevent the concentration of the drain current, particularly end concentration.

Abstract: PURPOSE:To respond to the change of linear velocity with simplified and inexpensive circuit configuration by frequency-dividing the oscilation output of a VCO with a frequency division ratio corresponding to designated linear velocity, outputting it as a reproducing clock, and varying the gain of a variable gain amplifier corresponding to the designated linear velocity. CONSTITUTION:Digital information data is recorded on a disk 1 by, for example, an EFM(Eight to Fourteen Modulation) system. A phase comparator 14 which compares the phase of an EFM signal of square pulse with that of the reproducing clock is provided at this PLL circuit 10 for clock generation, and the low- pass component of comparison output is passed through a low-pass filter 15, and goes to a phase error signal. The phase error signal is amplified with the variable gain amplifier 16, and goes to the control voltage of the VCO 17. A clock outputted from the VCO 17 is outputted as the reproducing clock in which it is 1/8-, 1/4-, and 1/2-frequency divided for the linear velocity with 1/2-frequency dividers 18-20 connected in series in three stages. In such a way, it is possible to respond to the change of the designated linear velocity with a single VCO.

Title: Amplifying device
Inventor: HORIKAWA KOJI
IPC: H03F1/32
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To enable high-efficiency signal amplification by placing N distortion control circuits and high-output amplifiers in balancing operation for N series of output signals distributed by a power distributing circuit for M input signals, compositing M output signals by a power compositing circuit, and controlling one of the phase and amplitude of a nonlinear distortion component. SOLUTION: Signals of inputs 1 to M of an input terminal 11 are distributed by the power distributing circuit 12 to N distortion control circuits 1 to N and high-output amplifiers 1 to N. Respective outputs of the high-output amplifiers 1 to N are put together by the power compositing circuit 15 and then outputted to respective corresponding outputs 1 to M of an output terminal 16. The distortion control circuits 1 to N and high-output amplifiers 1 to N perform balancing operation equally as to amplification characteristics of the signal components. The distortion control circuits 1 to N control not only the phases of distortion components, but also the amplitudes to some extent through mutually different functions, to reduce distortion components at the amplifier output terminal and distortion due to diffusion.  Consequently, signal amplification with high efficiency can be performed through the saturation point operation of the high-output amplifying device.
