Title: Inverter type bactericidal lamp
Inventor: SHIBANO MITSUO
IPC: A61L2/10
Filed: 1989-01-17
Abstract: PURPOSE:To have quick rising, drive with fine current, stable operation, and AC/DC switching by providing a power supply which can be changed over between AC and DC, and accomplishing high frequency drive using a transformer equipped with a specified core. CONSTITUTION:A limit switch 12 is closed by the suspension weight of an object to which the projected light from a bactericidal lamp is irradiated, for ex. a microphone, and current from AC mains energizes an oscillator transformer 1 for low frequency having a troidal core for low frequency. This induced signal current is rectified through a transistor 2 and fed to a choke transformer 3. An AC/DC changeover switch 11 allows changing-over from AC mains to a DC power supply 13. Current from the choke transformer 3 energizes an inverter transformer 6 having ferrite core for high frequency, and this high frequency power energizes a bactericidal lamp F1, etc. Use of ferrite core quickens rising and enhances the stability because of IC circuit.

Abstract: PURPOSE:To improve the stability to temperature with simple constitution without using a band extracting filter and at the same time to improve the frequency discriminating capacity, by using a PLL circuit consisting of a phase comparator and a VCO. CONSTITUTION:A PLL circuit consists of a phase comparator 10 which supplies an input signal (a) and a voltage control oscillator 11, and a signal (c) synchronizing with the signal (a) is produced.

IPC: H01L21/20
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To evaluate a crystal defect in a semiconductor single crystal film homoepitaxially or heteroepitaxially grown.

IPC: H01L21/336
Filed: 1988-01-18
Abstract: PURPOSE:To form a structure, in which threshold voltage is set easily while maintaining high withstand voltage characteristics, by making carrier concentration in a surface area to be a channel lower than one in the other area in a conductivity type diffusion region for forming the channel. CONSTITUTION:A second conductivity type diffusion region 2 for shaping channels is formed to the surface of a first conductivity type semiconductor region 1', and gate electrodes 5 are shaped onto surface areas 2b as the channels through insulating layers 12''. Carrier concentration in the surface areas 2b as the channels in the second conductivity type diffusion region 2 is made lower than that in other areas of said region. That is, even when carrier concentration in the surface areas 2b as the channels is lowered in order to be set within a practical threshold voltage range, a punch-through is difficult to be generated between a source and a drain because carrier concentration in other areas is made higher than that in the surface areas 2b. Accordingly, threshold voltage can easily be set while maintaining high withstand voltage characteristics.

Abstract: PURPOSE:To obtain an excellent copy image of high quality which has a good hue and no fog by comparing a ratio signal at the time of concentration detection with the ratio signal to an initial standard and controlling toner supply to a developing means according to the result. CONSTITUTION:A memory is stored with a value which indicates that a developer has a standard concentration value, i.e. the ratio of standard concentration reflected light quantity value data and standard reflection concentration pattern light quantity value data as standard developer concentration value data. Then an arithmetic circuit 13 reads a digital signal outputted by an A/D converter 11 and calculates the ratio of the both to recognize a developer concentration detection signal. Therefore, even if various optical systems decrease in illuminance or light quantity, there is no hindrance to proper developer concentration control and the developer concentration value in a developing device which is held proper is not affected. Consequently, the excellent copy image of high quality which has the good hue and no fog is obtained.

Abstract: PURPOSE:To deaden sound generated at the time of stopping by providing a switching means grounding a coil on the basis of a stop signal. CONSTITUTION:A switching element 9 grounds coils 2, 3 when a stop signal is input. Consequently, currents in the same direction are made to flow through the coils 2, 3 mutually wound in the opposite direction to the same pole shape, thus canceling the back electromotive force of an inductance section by the law of electromagnetic induction, then reducing currents generated by the back electromotive force quickly. Accordingly, saw-tooth current having a short period is generated as compared with the time of revolution. The waveform period is adjusted longer than periods in an audible range at that time, thus removing noises at the time of stopping.
