Title: Semiconductor integrated circuit device
Inventor: OKUYAMA KOSUKE
IPC: H01L27/092
Filed: 1986-06-25
Abstract: PURPOSE:To relax an electric field from a gate electrode and prevent the scattering of the electric field, and to improve electrical characteristics by causing carriers flowing between a source and a drain flow through a section deeper than the surface of a semiconductor substrate. CONSTITUTION:When the potential of a gate electrode 8 is at a high level, an energy band is pushed up by an electric field from the gate electrode 9. Since the energy level EC of the conduction band of a p-type semiconductor region 7 is positioned at a section upper than a Fermi level EF at that time, possibility in which there are carrier electrons in the p-type semiconductor region 7 is reduced extremely, and no channel is formed. Consequently, currents flowing between two n<+> type semiconductor regions 4 as source-drain regions flow in an n-type semiconductor region 6 shaped to a section deeper than the surface of a semiconductor substrate 1, not on the surface of the semiconductor substrate 1. Accordingly, the electric field from the gate electrode 9 working to currents flowing through the n-type semiconductor region 6 (a channel) is relaxed, and is not scattered by the surface, thus improving the mobility of carrier electrons.

Abstract: PURPOSE:To always stop a picture in a regular exposure position by performing fine adjustment of a picture structure to store the extent of this position correction when the picture is not in the regular stop state in a first position and using the stored extent of position correction for automatic frame feed to a second position. CONSTITUTION:Picture detecting sensors 37 and 38 to detect the edge position of each picture of a negative film 14 and film front end detecting sensors 39 and 40 to detect the front end of the negative film 14 are arranged on the film entrance side of windows 11 and 12.

Title: Motor controller
Inventor: KIMURA SHINSUKE
IPC: H02P3/22
Filed: 1995-06-14
Abstract: PURPOSE: To reduce the size of a controller itself by using one resistor commonly for both rush current restricting resistance and regenerative discharge resistance. CONSTITUTION: Since a switch (SW) 7 is turned off during closing of a power supply, a rush current can be restricted by charging a capacitor (CS) 3 through a diode (DD). Therefore, a resistor 21 plays a role of rush current restricting resistor. Also, SW 7 is turned on in a regenerative state, so that an electric charge of CS 3 is discharged through an SW 7 and a resistor 21 when a regenerative discharging switch 9 is turned on. That is, the electric charge of CS 3 is consumed by the resistor 21, and the resistor 21 plays the role of regenerative discharging resistance. DD 22 prohibits the short-circuit of CS 3 when the regenerative discharging switch 9 has turned on.  Also, the wiring of the resistor 21, CS 3 and the regenerative discharging switch 9 provides inductance, and this is turned on and off by the regenerative discharging switch 9, so that the DD 22 also functions as a flywheel diode.

Title: Optical rotating angle speed detector

IPC: G01C19/72
Filed: 1985-07-03
Abstract: PURPOSE:To reduce a measuring error caused by a variation in the wavelength of the output light of a light source by controlling the source to maintain the wavelength of the output light constant by the actually measured value of the wavelength obtained by wavelength measuring means by a wavelength controller. CONSTITUTION:Part of the output light of a light source 1 is branched by a half mirror 16 provided at an arbitrary position of a propagating passage to be eventually incident to a photodetector 6, and is incident to a photoreceiver (DET) 18 through a wavelength filter 17. When the central wavelength of the light incident to the filter 17 is displaced from a reference wavelength, the photoreceiver 18 outputs an output signal of lower level in response to the displacement, feeds a correction signal 121 to a drive power source 12 of a light emitting element 11 contained in the source 1 in a wavelength controller 12, thereby shifting the central wavelength so that the wavelength of the output light approaches a reference wavelength. Thus, since the source 1 is always regulated to output the light of the reference wavelength, a signal processor 9 can calculate an accurate rotating angle speed.
