Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a semiconductor device in which concentration of field can be avoided at the corner of a trench. SOLUTION: A silicon oxide 27, a silicon nitride 28 and a resist are deposited on the surface of a semiconductor substrate 1 and a trench 30 is made in the semiconductor substrate 1 by chemical dry etching through the opening. A wet oxide is then deposited on the inner surface of the trench 30 and the oxide is removed by wet etching to expose the surface of the semiconductor substrate 1 on the outer circumferential side of the corner part defined by the side face of the trench 30 and the surface of the semiconductor substrate 1. More specifically, the silicon oxide 27 is removed by self-aligned technology while leaving the silicon nitride 28 to expose the surface of the semiconductor substrate 1. Finally, the inner surface of the trench 30 and the exposed surface of the semiconductor substrate 1 are oxidized to form an LOCOS oxide layer which is eventually removed.

Title: Enclosed lead storage battery
Inventor: TSUBOTA MASAATSU
IPC: H01M2/18
Filed: 1985-11-18
Abstract: PURPOSE:To form an enclosed lead storage battery having an excellent life performance by forming band or dot type water repellent areas at a portion of a porous separator composed of fine glass fibers. CONSTITUTION:Band-shaped water repellent areas 3 are formed partially on a separator 1. Consequently, when a concentrated electrolyte held in the separator flows downward, and arrives at the water repellent area 3, it is repelled and rendered unpermeable to be blocked from flowing down furthermore. Since the water repellent area 3 formed in the porous separator 1 will serve as a dam, the electrolyte is prevented from forming layers in vertical direction of the porous separator 1. While since the water repellent area has the same porosity and elasticity with those of the hydrophilic area, it will never cause such detects as deterioration in the permeability of produced gas or the contact with the surface of the plate.

Title: Automatic intrusion detection system
Inventor: OKADA TOSHIMICHI
IPC: H04N7/18
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide an intrusion detection picture processing system which can monitor a wide range only by using one television camera and which can sufficiently suppress the increase of the cost required for constructing the system. SOLUTION: In this system capable of extending an image pickup range by mounting the television camera 2 is mounted on an electric universal head 17 and moving it, the dislocation of picture data which occurs by the movement of the television camera 2 is corrected by the pattern matching of picture data which are taken into picture memories 19 and 20 before and after in a frame unit to automatically and correctly obtain the intrusion object by an interframe difference. Since the influence of the dislocation of picture data by means of the movement of the television camera 2 can be eliminated, the television camera 2 can be moved and an image pickup field can be extended. Consequently, the sufficiently wide monitor area can be covered by one television camera and the system can inexpensively be constructed.

Title: Melting furnace for apparatus for drawing optical fiber and supporting structure for base material for optical fiber
Inventor: MIYAKO FUMIAKI
IPC: C03B37/027
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a melting furnace of a drawing apparatus capable of suppressing conditional change in the melting furnace even if local change of diameter of an optical fiber preform and quartz glass rod for auxiliary occurs.  
     SOLUTION: A top door 16 is installed so as to coincide with the installed center shaft of a heater 24 in order to constantly keep discharge of an inert gas 28 on a gas diffuser 20 and a groove 18 is formed in the inner circumferential face of the top door 16 to constitute a melting furnace 10. In the melting furnace 10, when an optical fiber preform 12 is inserted from the center of the top door 16, the inert gas 28 in the furnace is passed through the clearance 14. Since the top door 16 has an uneven structure formed by the groove 18, inert gas stream which passes through the clearance 14 has large resistance. Consequently, the influence on conditions in the furnace when the optical fiber preform 12 having local outside change is passed through the clearance 14 is relatively reduced.

Title: Liquid aspirator
Inventor: IMAZU MASANORI
IPC: G01N35/10
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To exactly distinguish a container by a simple constitution by judging a kind of a container corresponding to an existence or non-existence of an external force detection by an external force detection means. SOLUTION: In a state that a first unit 10 is positioned most recently, a pipette 12 is descended from an initial position through a washing part 60 by a predetermined distance by rotating a first motor 43 and a second motor 86 and descending a first retaining portion 30 and a second retaining portion 74 together while an engagement uninterfering state is maintained. During this time, a control portion monitors a signal from an external force detection circuit. If the pipette 12 detects an external force action, a container is judged as a closed container with a cap to stop a motor 43. In the case where the external force action does not exist even if the pipette 12 is descended by a predetermined distance, a container is judged as a released container with no cap.  Namely, since an existence or non-existence of the cap is directly detected and judged, an erroneous judgment is hardly caused. Since the device utilizes a constitution of a liquid aspirator and an external force detection means originally provided in an analyzer, the device is not made complex and large-sized.

Title: Matrix type liquid crystal display device
Inventor: MIYAZAWA YOSHINAGA
IPC: G02F1/1368
Filed: 1994-09-30
Abstract: PURPOSE: To decrease the light leakage by discrination and to make an opening rate as large as possible. CONSTITUTION: An arrow of a dotted line indicates the orientation direction of a lower oriented film and an arrow of a solid line indicates the orientation of an upper oriented film. The positions where the light leakage by the discrination occurs respectively vary with the differences in the orientation states. Light shielding films are, thereupon, formed to cover the regions where such light leakage occurs. The voltage supplied to scanning lines 31 is higher than the voltage supplied to signal lines 32 and, therefore, the device is preferably so formed that the side to decrease the light leakage by the discrination is the scanning line 31 side and the side to increase the light leakage is the signal line 32 side in order to additionally decrease the light leakage by the discrimination. Accordingly, the orientation states respectively shown in (B) and (D) are more preferable than the orientation states shown in (A) and (C) in the case of the four orientation states.

Title: Molding equipment for synthetic resin molded item
Inventor: SUZUKI TETSUHIKO
IPC: B29C43/56
Filed: 1986-10-31
Abstract: PURPOSE:To suppress the gasification of crosslinking agent during the course of reduced pressure in the pressure molding of synthetic resin stock and consequently prevent the surface quality from deteriorating by providing a control valve which reduces the pressure in a molding tool by opening a specified pressure reducing passage when a detecting means detects the timing to pressurize the synthetic resin stock in the molding tool. CONSTITUTION:A pressure reducing passage 7, which is open directly into a cavity 5, is provided at the end part of a molding surface 3b in a top force 3. The opening part 7a of the pressure reducing passage 7 is opened in the excessive part or non-product part of the cavity 5 normal to the molding surface 3b or vertically so as to be open to the side of the top force 3 by bending the passage sideways midway. When the signal to detect the pressurizing timing, at which the molding surface 3b of the top force 3 contacts a synthetic resin stock 6, is inputted from a detecting means 15 to a controlling means 14, the means 14 operates a selector valve 13 to its open position 13b and at the same time outputs the control signal to bring an on-off valve 9 to its closed state. Since the air and developed gas in the cavity 5 is sucked through the pressure reducing passage 7 at the early stage of the pressure molding, no bubble develops in a molded item. In addition, due to the short pressure reducing period, the amount of evaporated crosslinking agent is small and consequently a molded item, the surface of which hardens favorably, can be obtained.

Title: Evaluating method for semiconductor laser
Inventor: KAMITE KIYOTSUGU
IPC: H01S5/042
Filed: 1987-10-15
Abstract: PURPOSE:To observe an oscillation spectrum in the transient state of a DFB laser and to accurately evaluate transmission characteristic by applying a current for generating only a first optical pulse of a relaxation oscillation to the laser. CONSTITUTION:A transmission characteristic measuring pulse pattern generator 22 applies a DC bias current for generating only a first optical pulse of a relaxation oscillation to a DFB laser 24 and an electric pulse to be superposed thereon through a terminal T1. Then, the generation of an FP mode is confirmed. Thereafter, a channel selector 30 is switched to an optical fiber 40b, and the oscillation spectrum of the laser 24 is observed. Since an improper component for deteriorating the transmission characteristic and a proper component have different oscillation spectra of the FP mode, the component is proper or not is judged based on the depth of the FP mode.
