Patent JP-S554043-A (JP)
Title: Optical connector
Inventor: TACHIKURA MASAO
IPC: G02B6/38
Filed: 1978-06-26
Abstract: PURPOSE:To eliminate the clatter between plug and sleeve and perform connection of high accuracy by fabricating a groove to at least one of the outside circumference of the plug and inside surface of the sleeve thereby decreasing friction, air resistance. CONSTITUTION:With the sleeve 3 of the connector being intact, a serration (transverse groove) is provided to the outside diameter of the mating plug 1 and an axial groove (longitudinal groove) is dug in the place of a large diameter (the portion having the face which makes contact to the sleeve). Since such structure results in the reduced contact area of the plug and sleeve and the escape of the air in the plug readily to the outside by passing the groove of the plug, the clatter between both 7 may be suppressed and connection may be made with high accuracy by making the clearance between the plug and sleeve sufficiently small. In addition, the effect similar to the above may be obtained even by providing a longitudinal groove to the inside surface of the sleeve, a transverse groove to the outside circumference of the plug and further a screw groove or the like.

IPC: B41M5/145
Filed: 1992-03-31
Abstract: PURPOSE:To obtain a recording material enhanced in raw preservability and the storage stability of a developed color image by providing a recording layer containing a specific fluorane compd. (electron donating color forming compd.) and an electron acceptive compd. on a support. CONSTITUTION:A predetermined amount of a fluorane compd. represented by formula I (wherein R1 and R2 are a 1-12C alkyl group, a 3-12C alkyl group or a 5-12C cycloalkyl group and R3 is a hydrogen atom or a 1-4C alkyl group) and a predetermined amount of an electron acceptive compd. such as a phenol derivative are ground along with a water-soluble binder by a ball mill to be dispersed in and mixed with the binder to prepare a coating solution for a recording layer. This coating solution is applied to a support such as paper, a plastic sheet or synthetic paper and dried to form the recording layer to obtain a thermal recording material. Pigment, a water-insoluble binder, a surfactant, an ultraviolet absorber or hindered phenol can be added to the recording layer if necessary.

Title: Production of matrix array
Inventor: KODAIRA TOSHIMOTO
IPC: H01L29/786
Filed: 1995-03-31
Abstract: PURPOSE:To eliminate the influence of static electricity except a spot defect of one pixel so that generation of a line defect is averted by forming insulating films thicker than the first insulating film of capacitors for charge holding. CONSTITUTION:The interlayer insulating films are formed by first forming a silicon oxidized film 14-1 of a first layer over the entire surface of a substrate, then forming a silicon oxidized film 14-2 of a second layer over the entire surface of the substrate and etching away the oxidized films 14-2 exclusive of the intersected regions of gate lines 9 and source lines 10. In such a case, the thickness of the oxidized film 14-1 is specified to, for example, <=1000 angstrom in order to assure the capacitor capacity. The film thickness of the oxidized film 14-2 is specified to >=5000 angstrom by taking the voltage resistance between the lines 9 and 10 into consideration. As a result, the sufficient capacitance of the capacitors is taken and the voltage resistance at the intersected points of the lines 9 and 10 is set higher than the gate resistance of transistors. Then, the line-defects are not formed and the sufficient value of the capacitance of the capacitors is obtd. even if the defects generated by the electrostatic breakdown are corrected.

Title: Semiconductor device
Inventor: SHIMAZU KATSUHIRO
IPC: H01L29/786
Filed: 1990-03-28
Abstract: PURPOSE:To improve integration degree by forming CMOS transistors opposed to each other with a gate electrode used in common and reducing the area occupied by a semiconductor basic material to almost a half of the conventional device. CONSTITUTION:An N<+> type source 22, an N<+> type drain, a P<-> type channel 24, a common gate electrode 26 and a gate insulating film 30 are forming an N channel MOS transistor TR. Moreover, a P<+> type source 27, a P<+> drain 28, an N channel 29, a common gate electrode 26 and a gate insulating film 61 are forming a P channel MOSTR and respective regions of the P channel MOSTR. Thereby, since the area can be reduced almost to a half in comparison with that of the conventional semiconductor device, very high integration degree can be realized. Moreover, the N channel MOSTR and P channel MOSTR are perfectly isolated from each other by an insulating film at the area other than the common gate electrode and therefore a parasitic thyristor is never formed.

Title: Monitoring device for frequency hopping radio wave
Inventor: IIRI TOMOMI
IPC: H04B17/318
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a device capable of highly accurately monitoring frequency hopping radio waves. SOLUTION: The output signals of an amplifier means 2 based on the reception signals of an antenna 1 are received by searching a hopping band over plural times within one hopping time of frequency hopping by a reception means 3 and the continuous reception time of received radio waves for each frequency is obtained from the searched and received results of plural times by a detection means 4. Then, in the case that the continuous reception time is shorter than the transmission time of the object frequency hopping radio waves, elimination as noise is performed. When it is within the range of the transmission time of the object frequency hopping radio waves, detection is performed as the frequency hopping radio waves and prescribed information relating to the detected frequency hopping radio waves is outputted.  In the case that it is longer than the transmission time of the frequency hopping radio waves, the detection is performed as general communication waves.
