Title: Insulating gate type field effect transistor
Inventor: TAGAMI YUICHI
IPC: H01L29/41
Filed: 1988-09-26
Abstract: PURPOSE:To obtain a large gate length per exclusive area on a semiconductor substrate by disposing gate electrodes through a gate insulating film on the surface of a trench having an inclined face. CONSTITUTION:As gate electrodes 13-1 and 13-2 are disposed on the inclined face of a section inverse-trapezoid like trench 15 through a gate oxide film 14, a large gate width per exclusive area of a semiconductor substrate 11 can be obtained and making of a MOS transistor having a powerful drive capacity is realized. Since the gate electrodes are disposed on the inclined face, no disconnection of the gate electrodes takes place and it is easy to form source and drain regions 16-1,... by ion implantation. Although they have angles of inclination of 30-60 deg., it is preferable to have an angle of inclination of 45 deg.. If the gate width is compared with conventional one in terms of the same exclusive area on condition that the lengths of an inclined face and a base are (a) and (b), it increases by a factor of (1+b/2a)/(costheta+b/2a) in comparison with conventional gate widths.

Title: Semiconductor memory and semiconductor device
Inventor: OKASAKA YASUHIKO
IPC: G11C11/4074
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To increase the surge resistance of a semiconductor memory by connecting a first well region corresponding to each input terminal to a first upper layer power interconnection only via corresponding lower layer power interconnection. SOLUTION: The n-type well regions NW or power interconnections 1ALVCC of internal protective circuits corresponding to DRAM pads 5.1 to 5.N are not connected by other power interconnections to each other. Accordingly, the interconnection of the protective circuit for the pads 1.4 to 1.M and the interconnection of the protective circuit for pats 5.1 to 5.N are completely the same. Thus, even if a current flows from a resistance element 8 to the interconnection 1ALVCC2, the current does not further flow to the power interconnection 1ALVCC2 corresponding to other pads 5.1, 5.3 to 5.N via the other power interconnection, or does not further flow to the power interconnection 2ALVCC. The current flowing from the element 8 to the interconnection 1ALVCC2 is limited by connecting interconnections 10, 11.

Title: Solenoid type fuel injection valve
Inventor: KOSUGE TOKUO
IPC: F02M61/18
Filed: 1990-09-14
Abstract: PURPOSE:To secure desirable fuel distributing performance by having the relation of 0.002<=(ds-db)/db<=0.02 when the movable valve supporting part inner diameter of a turning member is made phids and the movable valve outer diameter is made phidb. CONSTITUTION:When the outer diameter of a ball valve 8 is made phidb and the inner diameter of a swirler 10 is made phids, it is so formed to have the relation of 0.02<=4(ds-db)/db<=0.02. With this relation between the outer diameter phidb of the ball valve 8 and the inner diameter phids of the swirler 10, even if the groove measure and eccentric quantity of the turning groove of the swirler 10 is dispersed and thereby fuel turning speed of each groove differs, the ball valve 8 is centered by the fuel flowing between the ball valve 8 and the swirler 10 by suppressing the upper limit of a clearance, thus obtaining uniform distribution. In addition, the shape accuracy of a fuel exhaust nozzle 9 is prevented from having an effect on the fuel distributing performance by securing this centering function.

Abstract: PURPOSE:To increase a limit speed due to seizure of a bearing and to improve machining precision, by providing a means which cools a bearing from its inner ring side in a way that cooling liquid is circulated from an external cooling liquid source to the interior of a main spindle for recovery. CONSTITUTION:The outer ring size of a front bearing 12 is cooled by a cooling liquid flow passage means situated to a static housing 14 to support an outer ring.

Title: Magnetic head
Inventor: FUSAYASU KOJI
IPC: G11B11/10
Filed: 1994-10-06
Abstract: PURPOSE: To remarkably improve reproducing sensitivity of a magnetic head in high density recording by providing a magnetic thin film connecting between magnetic cores confronted with each other and a magnetic flux convergence member along it. CONSTITUTION: A first magnetic core 1 is confronted with a second magnetic core 2 through a magnetic gap 5 arranged on a magnetic recording medium 6 side. A magnetic flux generated from magnetization by an information signal recorded on the magnetic recording medium 6 forms a closed magnetic path by the first magnetic core 1, the second magnetic core 2 and the magnetic thin film 3 constituted of a magneto-optical material. Further, a conductive member 4 as the magnetic flux convergence member is arranged along the bottom surface of the magnetic thin film 3. Since the direction of the closed magnetic path 12 formed inside a magnetic head repeats inversion at high speed according to the high speed movement of the magnetic recording medium 6, an eddy current occurs inside the conductive member 4, and reaction magnetic field occurs.  Thus, a leakage flux is reduced in the magnetic thin film 3, and its inside magnetic flux concentrates to an upper part on which light is made incident, and intensity of its magnetic field becomes large, and a rotation angle of magnetization on the surface of the magnetic thin film 3 becomes large, and the reproducing sensitivity of the magnetic head is improved.

Title: Supervisory method of transmission system data
Inventor: KUSUSE TAKASHI
IPC: H04J3/14
Filed: 1984-11-20
Abstract: PURPOSE:To detect an abnormality of transmission system data by storing two different reference voltages selected alternately at a period in a memory at the receiver side via a transmission system and comparing contents of the memory before and after the update. CONSTITUTION:A measuring data W converted into an analog value of a proper level by a converter 1 and a reference voltage S1 or a common voltage S2 of a DC voltage source 6 selected alternately by a switch 9 are multiplexed by a multiplexer 2 and transmitted to a transmission line 5a via an analog- digital converter 3, a serial/parallel converter 4 and a modulator 5. Thus, the data W and S1 and the data W and S2 are stored alternately in the memory 8 of the receiver 7. Since the data S1 and S2 are not equal, if the contents of the memory 8, the data S1 and S2 are compared and they are coincident, an abnormality of the switch 9 or the multiplexer 2 is detected.

Title: Picture processor
Inventor: UKEGAWA TAKESHI
IPC: H04N1/00
Filed: 1993-09-30
Abstract: PURPOSE:To prevent the erroneous reading by performing binarizing by comparing a multilevel picture signal which is converted by a multilevel picture signal conversion means with a threshold value located close to the black side selected by a threshold value selection means. CONSTITUTION:An input analog picture signal is converted into a multilevel digital picture signal by an A/D converter 1. At the time of reading an OMR sheet, the threshold value is selected to be located closer to the black side than the threshold value at the time of normal reading. Thus, it can be binarized by being compared with the threshold value close to the black side converted by the A/D converter 1. Thus, the threshold value closer to the black side than the threshold value at the time of reading the OMR is selected at the binary processing so that large burden on the system can be prevented. The black of the screen due to dust or the like can be prevented without increasing the cost of the device at the time of reading the OMR, resulting in preventing erroneous reading.

Title: Lighting device for discharge lamp
Inventor: NAKAGAWA NAOHITO
IPC: H05B41/282
Filed: 1987-09-30
Abstract: PURPOSE:To keep the change of the lamp current small and prevent the abnormal temperature rise of a circuit section even if the power source voltage is changed by providing a circuit detecting the temperature in a lighting device and varying the oscillation frequency of a fixed-frequency oscillating circuit. CONSTITUTION:When a lamp current is increased, the power consumption of a circuit section is increased, and when the ambient temperature of a discharge lamp lighting device is increased, a temperature-dependent resistor 40 detects the temperature rise, thus the resistance value is reduced. When the resistance value is reduced, the time constant of a charging circuit for a capacitor 14 is made short, and the Hi period of the output of a timer IC 50 is made short. The on period of a transistor 4 is thereby made short, thus the lamp current is decreased. When the lamp current is decreased and the ambient temperature of the discharge lamp lighting device is decreased, the resistance value of the temperature-dependent resistor 40 is increased, and the lamp current is increased.
