Patent JP-H0235408-A (JP)
Title: Microscope
Inventor: KONO YOSHIHIRO
IPC: G02B21/14
Filed: 1988-07-26
Abstract: PURPOSE:To obtain images with proper contrast with respect to various objects by arranging an opening slit having plural openings in positions apart from an optical axis and arranging a modulator having optical control areas corresponding to the openings. CONSTITUTION:The opening slit 13 has the openings 13a and 13b in the positions apart from the optical axis O, and the modulator 17 has the optical control areas 17a and 17b corresponding to the openings 13a and 13b respectively and both areas consist of three areas which are different from each other in transmissivity. Therefore in the constitution where the openings 13a and 13b are positioned apart from the optical axis, an opening area becomes larger than the opening area in constitution where the opening areas are positioned on the optical axis O, if both types of constitution are NA. Consequently an obtained image in the former constitution is brighter even if the focus depth in the former constitution is the same as that in the latter constitution. Besides, if both openings 13a and 13b are used, an image is obserbed in twice brightness, however the focus depth becomes shallow compared with the case in which only one opening is used. In this case, the directivity of modulation contrast effect is eased, and as a result, images with proper contrast with respect to many objects are obtained.

IPC: G01M3/18
Filed: 1982-10-26
Abstract: PURPOSE:To improve insulation between a core with and a metal well and to prevent erroneous operation due to dust, by providing a core wire coating layer, whose insulating property is lost by the contact of metal with metal sodium, at the exposed part of the core wire. CONSTITUTION:A detecting device is connected between a core wire 2 and a metal well 1. The core wire 2 comprises a conductive material, whose upper end is curved in a U-shape and folded. The well 1 comprises a cylindrical member, whose both ends are opened. The inside of the well 1 is filled with an insulating material 3 so that the lower end of the core wire 2 is exposed, and the well 1 and the core wire 2 are electrically insulated. A core wire insulating layer 2a is provided on the U-shaped folded part of the core wire 2, which is protruded from the upper surface of the insulating material 3. When the layer 2a is contacted with metal sodium, the insulating property is lost. When a sodium leaking fault occurs, the leaked sodium infiltrates through the layer 2a and reaches the core wire 2. A current bypasses a relay 6c, a relay contact point 6d is opened, and warning is issued.

Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To provide the PAL/SECAM signal discrimination circuit with an excellent temperature characteristic having a stable discrimination capability. SOLUTION: The PAL/SECAM signal discrimination circuit is provided with a voltage controlled oscillator 13 and a phase comparator 14 comparing a phase of a color burst signal with a phase of an oscillating signal from the voltage controlled oscillator to form a PLL.

Title: Semiconductor light-emitting element and manufacture thereof
Inventor: IIZUKA YOSHIO
IPC: H01S5/00
Filed: 1984-09-06
Abstract: PURPOSE:To position a linear active region positively at the center of a pellet while enabling cleavage without being disturbed by the malleability of an electrode material regardless of the thickness of a back-side electrode layer by forming a groove on the back side of a wafer in response to the active region and removing the back-side electrode layer on the line section of cleavage. CONSTITUTION:The back-side main surface of a wafer 11 is etched through chemical etching while using a photo-resist film 20 with an opening 22 as a mask to form a linear groove 23 to the back-side main surface. The photo-resist film 20 is removed, and a back electrode layer 24 is shaped onto the back of the wafer including the groove 23 by a material such as gold. Since the sections of the lines of cleavage X are removed as shown as removed sections 26 in the back-side electrode layer 24 on cleavage, the malleability of the material for the back electrode layer 24 does not obstruct the cleavage. Accordingly, the wafer can be cloven easily even when the thickness of the back-side electrode layer 24 is increased sufficiently.

IPC: H03M1/36
Filed: 1992-06-23
Abstract: PURPOSE:To provide an A/D converter which can decrease the deterioration of the converting accuracy due to the offset dispersion of a voltage comparator. CONSTITUTION:The reference voltage ET and EB (ET>EB) are applied to 1st and 2nd reference voltage input terminals 2 and 3 respectively. Under such conditions, the reference voltage having the subdivided scale (ET-EB)/256 (thereafter referred to as deltaE) is applied to one of both terminals of each voltage comparator 5. The output of a voltage comparator 5-2 is set at a high level when the analog input voltage applied to an analog signal input terminal 1 is higher than (EB+8deltaE). The high output of the comparator 5-2 is transmitted to a circuit 11. At the same time, the output of 3 less significant bits received from a digital signal generator 6 is supplied to an output terminal 13 of 3 less significant bits. Meanwhile the 3 less significant bits are obtained by a block 8 when the analog input voltage is lower than (EB+8deltaE). The block 8 contains the more number of voltage comparators included in a voltage comparison means as the input voltage to be compared are reduced.

Title: Method of capturing initial radio wave in gps receiver
Inventor: ISOMURA HIDETOSHI
IPC: G01S19/28
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To shorten position measuring work by dividing all channels into sets of two channels, and assigning two satellites rotated on the same orbit surface and situated in positions differed 180 deg. on the orbit to the channels of each set. SOLUTION: On an orbit A of the earth, four satellites A1-A4 arranged at equal angle intervals along the orbit surface are moved at a speed of about 12 hours per revolution. The satellite A1 is situated in a position 180 deg. opposed to the satellite A3, and when one is receivable, the other is surely situated in the unreceivable position. When the satellite A1 and the satellite A3, or the satellite A2 and the satellite A4 are combined together to one orbit, either one of them can be captured. A GPS receiver has the channel number of 8 or more, and they are divided into sets of two channels, so that satellites of at least four orbit surfaces can be assigned thereto. Thus, even when all the rough position, almanac data, and rough time of a receiving point are unknown, four satellites necessary for position measurement can be instantaneously captured.
