Filed: 1991-07-17
Abstract: PURPOSE:To prevent a deterioration of the breakdown voltage between a drain region and a source region of a high-voltage MOS transistor. CONSTITUTION:A drain region 3 and a source region 4 are formed in the area surrounded by a channel stopper region 2 on a semiconductor substrate 1. A gate electrode 6 is formed across the drain and source regions with an oxide film 5 interposed between the gate electrode and the regions. Formed above the drain region 3 are a drain electrode 7 and a drain electrode lead-out pattern 8 which extends from one part of the drain electrode. A low potential electrode 9 is formed at a location 20 defined by an intersection between an intermediate region, between the drain and the channel stopper region, and the drain electrode lead-out pattern 8 with a dielectric layer 10 interposed between the intermediate region and the electrode 9. The low potential electrode 9 serves as an electric field shield which prevents an electric field of the high potential drain electrode drawn pattern 8 from affecting the intermediate region between the drain and the channel stopper regions, thereby preventing the deterioration of the breakdown voltage between the drain region and the source region.

Title: Image forming device
Inventor: SOUMA TAKATAMI
IPC: G03G21/00
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent carrier from adhering to an image forming body even when a main switch is turned off suddenly in the midst of forming an image by providing a control circuit controlling the on/off of the output of plural high voltage power sources so that the control circuit may perform on/off control by holding the output by time in accordance with the holding characteristic of plural DC power sources. SOLUTION: This image forming device where development for an image forming body is performed by a contact reversal developing process is provided with the control circuit controlling the on/off of the output of the DC power sources A53 and B54 and the high voltage power source 55 having the different holding characteristic. An output control circuit 52 being one of the control circuit performs the on/off control by holding the output by the time in accordance with the holding characteristic of the power source B54. Thus, even when an area electrified before the main switch 56 is turned off reaches a developing area because the image forming body is rotated by its inertia when the main switch 56 is turned off, the carrier on a developer carrier is not transferred to the image forming body because developing bias voltage is impressed on the developer carrier.

Title: Control signal detection/protection circuit
Inventor: SAKAI KAZUNORI
IPC: H04Q9/00
Filed: 1986-07-25
Abstract: PURPOSE:To compress a circuit scale, by providing a protecting counter which decides the number of protecting stages of continuous detection signals, or continuous non-detection signals, and a means which decides control or non- control. CONSTITUTION:The detection signal 5 at an input terminal identifies whether a signal is the detection signal, or the non-detection signal, at a signal identification circuit 1, and sends out a count pulse to a shared protecting counter 2 when the same signals are issued continuously, and resets the shared protecting counter 2 when different signals continue. The shared protecting counter 2 sends a detection/protection signal 8 to a control circuit 3 when it counts continuously the number of protecting stages of set control signals and non-control signals, and simultaneously, sends a self-reset pulse to the shared protecting counter 2. The control circuit 3 sets a flag representing a controlled state, or a non-controlled state, based on the signal from the shared protecting counter, and outputs a control signal detection/protection signal to an output terminal 6. Thus, by forming a circuit in the shared protecting counter, it is possible to reduce the circuit scale almost by half.

Title: Guide roll and guide shaft for magnetic tape and their production
Inventor: MURAKAMI YUKIYOSHI
IPC: G11B15/60
Filed: 1985-08-09
Abstract: PURPOSE:To improve both wear resistance and machinability together with the reduction of cost of a guide roll and a guide shaft for magnetic tape, by using a brass or aluminum material of a paramagnetic substance to an inner member and forming an outer circumference part of the inner member with the film of a nickel alloy having the hardness of >=HV500 and subjecting to a demagnetizing process. CONSTITUTION:A guide roll consists of the inner member 1 made of the brass or aluminum material of the paramagnetic substance which can be easily processed and the outer circumference part 2 formed with the film of a nicke-phosphorus alloy. Thus the hardness of the guide roll is increased up to >=HV500 together with improvement of the surface coarseness. The member 1 subjected to machining is applied to a rolling dice having a smooth surface to improve the smoothness of the outer circumference surface of the member 1. At the same time, the hardness of the material is increased by rolling. Thus no injury is produced when a barrel is ground in the next process and the barrel grinding process is applied to increase more the smoothness of the outer circumference surface of the member 1. Then a plating process is applied to improve the hardness and the surface coarseness of the member 1 so that it can be well used with a metallic tape. Furthermore the roll is put into a heating furnace to undergo a heating process. Thus the hardness of the guide roll is increased up to about HV500-HV1,000.

Abstract: PROBLEM TO BE SOLVED: To narrow the width of so called, a frame part in the circumference of a screen by obliquely forming a part where an input and an output terminal are connected to each other. SOLUTION: The part connecting mutually the input terminal 1, 3 of the electrode 31, 32, which is provided each on the electrode substrate 11, 12 constituting a liquid crystal display device 62, with the output terminal of a tape carrier package 6, is formed obliquely against the electrode 31, 32. Accordingly, the part can be removed which is arranged each vertically against the side at the end of the electrode substrate 11, 12, where conventionally the input terminal 1, 3 of the liquid crystal display device 62 is arranged; therefore, a distance can be reduced between the lighting display area 5 and the input terminal 1, 3, enabling the width of the frame part to be shortened where the input terminal 1, 3 and the drawer type wiring 2, 4 outside the lighting display area 5 are formed.  Thus, the outside dimension of the liquid crystal display device 62 can be reduced, facilitating a large screen, miniaturization and light weight of an information processing device such as a personal computer and a word processor.

Title: Coriolis mass flowmeter
Inventor: OSAWA NORIKAZU
IPC: G01F1/84
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To achieve high accuracy and improve heat resistance and pressure resistance by absorbing thermal expansion and vibrations by means of a soft structural body set at both ends of a vibration tube and obstructing a deformation of the tube by a backup part. SOLUTION: A fluid to be measured is fed to a vibration tube 11, and an oscillator 15 is driven. A vibration amplitude of the vibration tube 11 proportional to an acting Coriolis force is measured. A mass flow rate is operated from a phase difference of an upstream and a downstream vibration detectors 16, 16. Although a soft structural part 13 is deformed at this time because of a thermal expansion and a pressure increase of the fluid, in general usage, the structural part 13 changes its shape freely without touching a backup part 14 of a housing 12 and absorbs the thermal expansion and vibration. However, when an extraordinary thermal expansion or pressure is applied, the structural part is greatly deformed into touch with the backup part 14 and consequently not deformed any more.  In other words, the soft structural part 13 lessens influences of the thermal expansion, thereby enabling highly accurate measurements. The soft structural part 13 is prevented by the backup part 14 from being plastically deformed and broken against the extraordinary thermal expansion or pressure, and improved in heat resistance and pressure resistance.
