Title: Semiconductor device
Inventor: UCHIDA HIROBUMI
IPC: H01L21/8226
Filed: 1986-10-20
Abstract: PURPOSE:To produce an integrated injection logic (I<2>L) device consuming less power by a method wherein an insulating layer is provided just under a P-type diffusion layer to be the emitter of a lateral PNP transistor. CONSTITUTION:A lateral PNP transistor is built of a P-type diffusion layer 51 as an emitter, P-type diffusion layer 52 as a collector, and an N-type base 4. A vertical NPN transistor is built of the P-type diffusion layer 52 as a vertical NPN transistor, N-type epitaxial layer 4 as an emitter, and an N-type diffusion layer 6 as a collector. This design differs from that of conventional ones in that a silicon dioxide layer is formed just under the P-type diffusion layer 51 serving as the emitter of a lateral PNP transistor. With the device being designed as such, there is no injection of holes from the lateral PNP transistor emitter downward. Hole injection takes place only laterally, which reduces reactive currents and consequently power consumption.

Title: Color separation circuit
Inventor: KIRIYAMA TAKASHI
IPC: H04N9/78
Filed: 1990-09-19
Abstract: PURPOSE:To exactly detect the phase shift of a color demodulation axis even when the level of an input signal is low by calculating the phase shift between a color burst and the color demodulating axis based on the output values of two average value calculation circuits and outputting the phase shift to a color separator. CONSTITUTION:An average value calculation circuit 12 inputs a sampling clock (k) from an input terminal 15, samples a value in the color burst block of a color difference signal e(R-Y) constant times, calculates the average of the sample values for each line and outputs an average value l(R-Y) to a color burst phase shift calculation circuit 14. An average value calculation circuit 13 similarly outputs an average value m(B-Y) to the color burst phase shift calculation circuit 14. Based on the average values l(R-Y) and m(B-Y), the phase shift calculation circuit 14 calculates the phase shift between the color burst and the color demodulating axis and outputs it to a color separator 5. Thus, even when the amplitude of the color burst of the input signal is low, the phase shift of the demodulating axis can be accurately detected.

Abstract: PURPOSE:To prevent malfunction of detecting a paper jam due to bending of a recording sheet by operating recording sheet detecting means plural times in case of recording on one recording sheet, and deciding that a paper jam is not caused when a recording sheet is detected once. CONSTITUTION:A photosensitive drum 2 is rotatably installed in a copying machine body 1, and a paper feed cassette 9 where copy sheets 8 as a recording sheet are loaded is detachably mounted therein.

Filed: 1989-09-26
Abstract: PURPOSE:To make value of inductance large and adjust easily variations of inductance as well by forming slits at the lower part of a magnetic substance located on the upper surface of each face conductor pattern part. CONSTITUTION:In a plane coil 1, a magnetic substance 21 is provided newly even on the upper surface in addition to a magnetic substance 22 at the lower face of the coil.

Title: Shaft voltage preventing apparatus for turbine generator
Inventor: EBARA TAKEHIKO
IPC: H02K5/16
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain a shaft voltage preventing apparatus for turbine generator requiring no periodic replacement in which the gear face in a reduction gear is protected against damages. SOLUTION: A discharge electrode unit 5, for preventing shaft voltage comprising a pointed protrusion electrode 51 and a pointed and grounded protrusion electrode 52 disposed facing thereto, is provided at the shaft end of a turbine. A discharge starting voltage between the protrusion electrodes 51, 52 is set lower than the withstanding voltage of oil film in a turbine bearing 13 or a generator bearing. Since the shaft voltage generated in a turbine blade 12 due to static charges drops below the withstanding voltage of oil film in the bearing through discharge between the protrusion electrodes 51, 52, it is not discharged to the bearing. Since the shaft voltage is not discharged from the generator side, gear face in a reduction gear between the turbine and the generator is not damaged, and since noncontact grounding of shaft voltage is employed, frictional abrasion will not occur.
