Patent JP-H0677237-A (JP)
Title: Manufacture of planar type diode
Inventor: ARAI TAKAO
IPC: H01L21/329
Filed: 1992-05-27
Abstract: PURPOSE:To decrease the pellet size by a method wherein an insulating film provided on a semiconductor substrate is diffused with impurities from mesa type aperture parts separated from each other so as to form mutually connected ring type diffused layers. CONSTITUTION:The surface of an N type silicon substrates 4 in aperture parts 3 is thermal-diffused with acceptor impurities such as boron, etc., using a silicon oxide film 2 as a mask so as to form P type impurity diffused layers 4 as well as forming silicon oxide film again on the surface of the silicon substrate in the aperture parts 3. Next, the P-type impurities are diffused in the parts of intervals (d) to be coupled with one another in a ring shape by this thermal oxidizing step. At this time, the acceptor concentration inside 12 of the corner part of the P-type impurity diffused layers 4 is made lower than that inside 11 of the linear part of the P-type impurity diffused layers 4 so as to stiffen the electric resistance in the corner parts of the P-type impurity diffused layers 4. Through these procedures, the current concentration in the corner parts, when impressed with short pulse surge, can be avoided thereby enabling the surge breakdown to be notably increased.

Title: Camera with visual line input function
Inventor: KITANI KAZUNARI
IPC: G03B17/02
Filed: 1994-05-26
Abstract: PURPOSE:To enable the action of detecting visual lines to be initiated in a natural state without performing any special operations and to indicate that the action is taking place by initiating the action of detecting visual lines when detecting the approach of a photographer's eye. CONSTITUTION:While a photographer is looking into a viewfinder, an infrared ray emitted from a light-emitting element 1 is reflected at the eye ball, impinges again on an eyepiece 4, and forms an image on a photocell 6. When detecting the approach of the photographer's eye, an arithmetic processing circuit 13 feeds a signal to a control circuit 11, which in turn, starts the action of detecting the direction of the visual line of the photographer. The control circuit 11 first causes all ranging points within the field of view of the viewfinder to blink. Under these conditions, the direction of the visual line of the photographer is detected and the corresponding ranging point is turned on or kept blinking to clearly indicate the ranging point selected. Also, a visual line detecting function is used to clearly indicate that the selection of any ranging point is still possible. When a shutter release is half-pressed under these conditions, the ranging points not selected are turned off.

Filed: 1984-06-28
Abstract: PURPOSE:To clean up a sheet body with large diameter evenly by a method wherein multiple linear jetting tubes are arranged in parallel with one another at specified intervals while a sheet body to be cleaned up is shifted in the perpendicular direction to the processing solution jetted from the jetting holes. CONSTITUTION:Jetting tubes 12-16 are respectively provided with linear jetting holes 17 jetting processing solution like curtains while a semiconductor wafer 18 is shifted downward in almost rectangular direction to the processing solution jetted from the jetting holes 17. The top jetting tube 12 jets developing solution while the jetting tubes 13-16 jet cleaning solution for washing. The wafer 18 wetted by the jetting tube 12 is rapidly cooled down and cleaned up by the cleaning solution for washing from the jetting tube 13. Through these procedures, the chemical change in developing solution on wafer surface may be stopped instantaneously to control the development reaction properly while completely cleaning up the surface of wafer 18 by the cleaning solution for washing from the jetting tubes 14-16.

Title: Chemical bath for immersing article in liquid chemical substance
Inventor: ARAN BAAMAN
IPC: B01L99/00
Filed: 1991-06-06
Abstract: PURPOSE: To provide a chemical bath for immersing integrated circuit wafers or other articles in a liquid chemical substance. CONSTITUTION: A chemical bath comprises a processing vessel 16, an adjacent sump vessel 22 and a trough 18 for transferring overflow from the processing vessel 16 to the sump vessel 22. A pump continuously recirculates liquid from the sump vessel 22 to the processing vessel 16 through a filter. A continuous inflow of liquid chemical substance is received from a liquid chemical source, and an intermittent overflow occurs through an outlet at an upper region of the sump vessel 22. The storage capacity of the sump vessel 22 below the outlet is greater than that needed to contain the volume of liquid that is displaced in the processing vessel 16 by a batch of wafers 12.  This avoids pump starvation when liquid level is lowered in the processing vessel 16 by removal of the batch of wafers and also assures that outflow matches inflow without requiring flow sens devices, dynamic valving or other complicated equipments and operations.

IPC: H01L29/10
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To compatibly realize a reduction in leakage current and improvement in the reliability of a gate insulating film. SOLUTION: In a method for manufacturing semiconductor device, a gate insulating film 9 and an insulating film 10 are formed on the main surface of a semiconductor substrate 1 as oxide films by subjecting a channel layer 7 containing nitrogen to thermal oxidation, after the layer 7 is formed in a channel region 5 in the main surface of the substrate 1. Since oxidative reactions are suppressed in a nitrogen-introduced region, the insulating film 10 is formed larger in thickness than the gate insulating film 9. In addition, the occurrence of stresses caused by the oxidation is suppressed, in the periphery of the connection between the gate insulating film 9 and insulating film 10.

Title: Color picture tube
Inventor: KIKUOKA TAKASHI
IPC: H01J29/88
Filed: 1984-06-29
Abstract: PURPOSE:To enable an inner conductive film to be formed simply and accurately by forming an inner conductive film which extends from a raised stage formed on the inner surface of the funnel glass. CONSTITUTION:A raised stage 10b is located in the back of the sealing surface 10a of a funnel glass 10 by a given distance (l) along the direction of the tube axis. The distance (l) is adjusted to be about 3mm.-15mm. as in a conventional color picture tube. When the height (h) of the raised stage 10b is 0.5mm. or below, the end of a brush 4 touches the inner surface 10c. When the height (h) is 5mm. or greater, the funnel glass 10 becomes thin in the area on which the inner surface 10c is formed and the mechanical strength of the funnel glass 10 decreases. Additionally, there is a possibility that the area of the sealing surface 10a decreases and only incomplete fusion is produced. Therefore, the height (h) is adjusted to be within the range of 0.5mm.-5mm.. By the means mentioned above, it is possible to accurately maintain the distance (l) between the sealing surface 10a and the end 3a of an inner conductive film 3 without accurately applying a conductive paint using the brush 4 during formation of the inner conductive film 3.

IPC: H02P7/29
Filed: 1987-05-30
Abstract: PURPOSE:To miniaturize a device and lighten the weight of it, by controlling a power transistor with motor-ON/OFF-signal from a governor circuit and the motor-ON/OFF-signal due to the starting or stopping of a motor. CONSTITUTION:When motor-ON-signal b is fed to a controlling terminal 14, then the signal of an L-level is fed from a voltage comparator 16. Then, a transistor (Tr) 20 is interrupted, and a Tr 12 turns conductive, and driving current is fed to a motor 13. When the speed signal (f) of the motor 13 exceeds reference voltage, then the output signal of a voltage comparator 28 is changed to come to the L-level. As its result, the output signal of the voltage comparator comes to an H-level, and the Tr 20 turns conducting, and the Tr 12 is interrupted, and the driving current fed to the motor 13 is interrupted. In this case, current due to the electromotive force of the motor 13 flows via a diode 22 and the Tr 20, and a brake is worked.
