Filed: 1987-10-26
Abstract: PURPOSE:To realize a high speed by a method wherein a high impurity concentration region of an opposite conductivity type whose impurity concentration is higher than that of an epitaxial layer is installed in a channel MIS transistor of one conductivity type and a high impurity concentration region of the one conductivity type which is deeper than a source region and a drain region is installed in a channel MIS transistor of the opposite conductivity type. CONSTITUTION:An n-channel MOS transistor (n-MOS) whose conductivity type is opposite to that of a substrate body, i.e. a p<--> type epitaxial silicon layer 3, is divided into pieces by p-type channel stoppers 5 which have been formed under a field oxide film 4; it is arranged immediately in the p<--> type epitaxial silicon layer 3 of low impurity concentration. A p<-> type region 17 of high impurity concentration which is deeper than a source region and a drain region 14, 15 is installed selectively in a channel formation region; a punchthrough between the source and the drain can be prevented. In addition, because a junction of the source region and the drain region 14, 15 is formed between them and the p<--> epitaxial silicon layer 3 of low impurity concentration, their junction capacitance value becomes low. By this setup, a high speed can be realized.

Title: Rotary mirror scanner
Inventor: HARII PII BURIETSUGUMAN
IPC: G02B27/00
Filed: 1988-10-26
Abstract: PURPOSE: To eliminate the difference in the scanning length between multi-beams by mutually tilting the beams toward the surface of a photoreceptor. CONSTITUTION: Lasers 10 and 11 are mutually tilted by an angle αwith each other. This differential tilt angle α applies a little different scanning lengths to the beams of a photoreceptor surface 50 concerning a certain rotating angle of a polygon 12, and the more an incident angle I1 is reduced in the 1st reflection of facet 22, the longer the beam is scanned. Namely, a beam 5 scans the surface of a photoconductive drum 50 for the distance longer than a beam 5A and the excessive moving distance of this beam 5A enables the scan for long distance on the drum 50. Therefore, by properly selecting the tilt angle, the scanning length of beams 5A and 5 can be made equal.

Abstract: PURPOSE:To do P-type diffusion with excellent controllability from a diffusion source separated from an emitting region to a photowave guide region excluding an element edge and its vicinity by performing the diffusion of impurities to an active layer through a ridge. CONSTITUTION:Each layer is grown on a substrate in order from a lower clad layer 2 to the second upper clad layer 5 of P-type AlGaAs, and further an n-type GaAs cap layer 21 is grown. After Zn is diffused to the cap layer 21, an Si2N4 insulating film is made on the whole of an element surface, and a stripe-shaped insulating film 22 covering both ends of the element in the direction of resonator length is made. Subsequently, with this as an etching mask, it is etched to the level that the second upper clad layer remains little so as to form a ridge. When drive in diffusion of Zn is done through the ridge 23, a low concentration P-type region 12 reaches an active layer 3. Next, an n-type GaAs current checking layer 6 is grown until the ridge 23 is buried. Since a strip-shaped insulating film 22 exists on the ridge 23, selective growth is done, and the wafer is flattened.

Title: Preferential control circuit for asynchronous precedent signal
Inventor: WATANABE HIROAKI
IPC: H03K17/00
Filed: 1993-10-29
Abstract: PURPOSE:To suppress the extension of circuit scale even when the number of inputs is increased by successively sampling plural output request signals to be asynchronously inputted with the output of a sampling signal generation part and defining an output signal latched by a latch part as an output permit signal when the sampling signal generation part stops operation. CONSTITUTION:The plural output request signals to be asynchronously inputted are successively sampled by the output of a sampling signal generation part 1, and the sampled output request signals are outputted from a sampling part 3 to a latch part 2 with the output of the generation part 1 as a clock. These sampled signals are transmitted to a request signal detection part 4 as well. In this case, when the output request signals are sampled and detected by the detection part 4, the operation of the sampling signal generation part 1 is stopped and the output request signal latched by the latch part 2 at that time is defined as the output permit signal so that preferential control of asynchronous precedent signal can be performed. In this case, the extension of circuit scale is suppressed small in comparison with the conventional example.

Title: In-operation calibrator for pressure detector for liquid metal
Inventor: OZAWA KENJI
IPC: G01L27/00
Filed: 1985-12-03
Abstract: PURPOSE:To enable a pressure detector to be calibrated without being demounted by providing a calibrating pressure vessel and a calibrating line connected thereto. CONSTITUTION:A calibrating instrument is provided with a calibrating pressure vessel 32 that is so mounted as to airtightly cover a pressure transducer 28 and with a calibrating line 34 connected to the vessel 32. A normal measurement is conducted in a condition that a three-way valve 44 is opened to the side of an open conduit 46 and that the internal pressure of the vessel 32 is kept constant. This is because, if the transducer 28 was in a closed condition, the internal pressure of the vessel 32 would be changed by a change in temperature or the like to produce an error in the pressure being measured. After calibration data are made, the system to be measured of a plant or the like is provided with a pressure detector 16 having the calibrating instrument. When an inoperation calibrating test is conducted as the instrument is installed to the plant, a reference calibrating pressure is applied to a calibrating pressure conduit 42 from a calibrating pressurizer 48 and the value indicated by the detector 16 is read to make a calibration curve. By comparing the data thus obtained with calibration data that have been obtained in a primarily measured diaphragm pressure and calibrating the detector 16, a highly accurate calibration can be performed without dismounting the detector 16.
