Title: Base precursor
Inventor: YABUKI YOSHIHARU
IPC: C07D233/22
Filed: 1987-06-17
Abstract: PURPOSE:To obtain a base precursor which is composed of a carboxylic acid and an organic base, thus being used as a thermal developing type recording material, because it is very stable during the storage and readily liberate the base, when heated. CONSTITUTION:The subject base precursor is obtained by combining appropriately salts derived from carboxylic acids and organic base of the formula (R<1>-R<4> are H, alkyl, alkenyl, alkinyl, aralkyl, a monovalent group from N-containing heterocyclic ring). The carboxylic acid is preferably sulfonylacetic acid or propiolic acid in which the carboxyl group is eliminated by decarboxylation under heating at 50-200 deg.C. The salts from the carboxylic acid and the organic base melt at 50-200 deg.C.

Title: Plug sealing method and plug sealing
Inventor: MIHARA HIROMASA
IPC: B67B3/00
Filed: 1987-06-19
Abstract: PURPOSE: To make sealing easier by presealing a container with a seal, attaching a closure body, and thermally bonding the seal and closure body and to make the both detachable as one body when the stopper is pulled out. CONSTITUTION: A bottle 12 is pre-sealed by a press-fitting seal 11 to the bottle 12 and a bonding 13 between the bottle 12 and the seal 11. A closure body 10 is seamed, screwed or press-fitted to the neck of the bottle. At the same time, the closure body 10 and the seal 11 are adhered and integrated using a pressure-sensitive adhesive, etc. Accordingly, the seal 11 can be detached from the bottle 12 together with the closure body 10 when the stopper is removed, thus the removing of the stopper becomes easy. Moreover, since the seal conducts pre-sealing merely by adhesion, thermal welding or pressing-in, the structure of the machine for furnishing a seal is simplified.

Title: Structure of pressure sensor
Inventor: WAKAYAMA KIYOSHI
IPC: G01L19/14
Filed: 1989-06-14
Abstract: PURPOSE:To eliminate a change with time in relation to a high pressure, to improve performance and reliability and also to attain simplification of a structure and reduction of cost, by joining a case and a pressure-sensitive element together by laser welding or electron beam welding. CONSTITUTION:A pressure-sensitive element 1 is inserted into a cavity C of a case 2 from a direction A so that the opening 10 thereof is exposed directly to the outside air. In order to join and fix the pressure-sensitive element 1 and the case 2 together airtightly, laser welding or electron beam welding 3 is conducted. In addition, the laser welding or electron beam welding 3 is conducted along the part of their abutment, i.e. the face of contact of an annular projection 9 of the pressure-sensitive element 1 with the inside surface of the case 2. Moreover, an annular collar 5 is disposed in contact with the annular projection 9 inside the cavity C. This annular collar 5 is useful for protecting communication members of lead wires led out of the pressure-sensitive element 1 and others with the outside. In the laser welding or electron beam welding, the effect of temperature on the pressure-sensitive element 1 and the case 2 is less than in arc welding, and also a welding operation can be performed in a short time.

Title: Spatial light modulating element
Inventor: NATSUBORI YASUYUKI
IPC: G02F1/135
Filed: 1993-05-29
Abstract: PURPOSE:To obtain excellent display performance by reducing warping of a transparent substrate caused by a temperature change even if coefficients of thermal expansion of the transparent substrate and a light conductor of a spatial light modulating element are different from each other. CONSTITUTION:When a coefficient of thermal expansion of a light conductor 16 is small to a transparent substrate 20, the light conductor 16 side warps in a projecting shape as shown in (A) according to a temperature change. When an intermediate layer 50 having a coefficient of thermal expansion larger than that is formed on the transparent substrate 20, the intermediate layer 50 side warps this time in a recessed shape to the contrary as shown in (B). In this way, the relationship between a recess and a projection is reversed in response to the relationship of dimensions of the coefficient of thermal expansion. Thereby, when the intermediate layer 50 is formed between the transparent substrate 20 and the light conductor 16 as shown in (C), warping in the projecting direction of (A) and warping in the recessing direction of (B) are cancelled each other, and as a result, the warping is reduced.

IPC: G06K9/03
Filed: 1979-11-22
Abstract: PURPOSE: To decrease a misreading rate without decreasing a correct reading rate with regard to characters meeting standard requirements by making use of a recognizing circuit high in correct reading ratio having been developed yet and by adding an additional function by selecting a deciding circuit side with a switch.  
     CONSTITUTION: An input pattern is processed by recognizing circuit 1, which outputs some answer or a reject code and various parameters regrading the input pattern. When the side of the 1st deciding circuit 3 is selected with switch 2, circuit 3 refers to checking memory table 5 predetermined for every answer as to the answer obtained by circuit 1 and the parameter input, thereby determining whether there is a required parameter and disused parameter and whether the rejected character is rejected in the mode determined by table 5 or sent to the 2nd deciding circuit 7. This circuit 7 makes an analysis by laying emphasis on characteristic check points of the sent answer to decide whether it should be outputted as an answer or rejected.

Title: Voltage comparator with built-in hysteresis
Inventor: KASHIAI HIROMI
IPC: H03K3/2897
Filed: 1986-06-27
Abstract: PURPOSE:To easily set a hysteresis voltage with high accuracy while decreasing the number of components to reduce the cost, by connecting a collector of a transistor (TR) for a 1st differential amplifier to a reference potential point. CONSTITUTION:A TR 23 is a PNP TR as the 1st differential amplifier TR and a TR 24 is a PNP TR as the 2nd differential amplifier TR. In applying a voltage sufficiently lower than a reference potential of a reference potential point 5 to an input terminal 3, the TR 23 is turned on and the TR 24 is turned off. In this case, since a current I12 from a constant current source 12 flows to the reference potential point 5 from a collector of the TR 23, the level of the reference potential is increased by a value of I12 X R4. Conversely, in applying a voltage sufficiently higher than the reference potential of the reference potential point 5 to the input terminal 3, the TR 23 is turned off and the TR 24 is turned on. Since no current flows from the collector of the TR 23 to the reference potential point 5 in this case, the reference potential is not increased.
