Patent JP-H01178918-A (JP)
Title: Waveguide type optical modulator
Inventor: HATORI MASAMI
IPC: G02F1/125
Filed: 1987-12-29
Abstract: PURPOSE:To suppress the attenuation of surface acoustic waves low within a range wherein it crosses waveguide light by arranging an IDT (Inter Digial Transducer) which generates surface acoustic waves at the nearly breadthwise center position of the waveguide light. CONSTITUTION:The IDT 15 which generates the surface acoustic waves 12a and 12b is arranged in an optical waveguide 11 at the nearly breadthwise center position of a light beam 13 propagated in the optical waveguide 11. The surface acoustic waves 12a and 12b which are generated by the IDT 15 are propagated in two directions so as to travel from the nearly breadthwise center part of the light beam 13 to right and left end parts. Thus, the distances where the surface acoustic waves 12a and 12b which are propagated in the mutually opposite directions cross the light beam 13 are almost a half as long as the distance where one surface acoustic wave crosses the light beam from one end to the other like a conventional device. Consequently, the extent of the attenuation of the surface acoustic waves 12a and 12b by absorption by the waveguide 11 while the waves cross the light beam is suppressed lower than the conventional device.

IPC: B30B11/02
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a compact high in shape accuracy by charging powder in a molding flask rigid to hydrostatic pressure, inserting a molding punch into the molding flask so that it can slide freely on the inside of the flask and driving it at a hydrostatic pressure to compact the powder. CONSTITUTION:The molding flask 1 is a rigid molding flask made of material such as acrylic resin, etc., mounted on a press mold and the molding punch 2, too, is a rigid punch made of material similar to that of the flask. The structure of the molding flask can be made freely according to the shape of the compact but a builtup molding flask is preferred to improve the releasing property of the compact after it is molded. The rigid molding flask and the molding punch are light-weight and of low cost and can be made easily large-sized. In this way, the compact high in shape accuracy can be obtained easily and at low cost by carrying out cold hydrostatic press molding. Further, since this is a builtup molding flask, it can prevent generation of cracking surely in time of mold removal.

Abstract: PURPOSE:To enable a uniform dividing of flow of refrigerant to be carried by a method wherein a refrigerant flow divider is comprised of a hollow body, a plurality of flow- out pipes fixed in sequence in a longitudinal direction of the hollow body and a feeding-in pipe inserted up to an end part, and the feeding pipe is provided with a flow-out hole of which diameter is decreased from an upper part to a lower part. CONSTITUTION:A refrigerant flow divider 11 is comprised of a cylindrical hollow body 2, a feeding-in pipe 3 inserted from a lower end 2L of the hollow body 2 to a part near an upper end and a plurality of flowing-out pipes 4 equally spaced apart at an outer circumferential side surface 2S of the hollow body 2. Refrigerant R for a heat exchanging operation passes from the flowing-in pipe 3 through a flowing-out hole 6 and into the hollow body 2. The refrigerant R of two gas and liquid phases has much volume of liquid compound in the flowing-out hole 6 and there are much amount of gaseous component in the upper flowing-out hole 6. Since the flowing-out hole 6 is reduced as it is lowered, refrigerant of much volume is flowed from the lower flowing-out hole 6. Accordingly, the refrigerant amount in respect to its weight is uniform in each of the flowing-out holes 6 and then an approximate uniform flow division of the refrigerant R for an entire flowing-out pipes 4 can be attained.

Title: Inter-processor vector interruption control system
Inventor: OTSUKI HARUHIKO
IPC: G06F15/177
Filed: 1989-12-25
Abstract: PURPOSE:To freely set and cancel the master-slave relation between processors by providing an interruption request signal line which transfers an OR of interruption signals and an interruption answer signal line which transfers an OR of interruption answer signals. CONSTITUTION:A polling address generating circuit 1 monitors an interruption request signal (e) and fixes a polling address (a) when the signal (e) is activated so as to prevent the address (a) from applying a polling operation to the next processor. Meanwhile a latch gate 9 is kept open for a processor 3 since an output (g) is active, and an interruption answer signal (f) is directly received as an interruption answer (k). Thus the reception of an interruption is confirmed. At the same time, the circuit 1 monitors the interruption answer signal (f) and confirms the end of an interruption procedure when the signal (f) is active to restart the polling operation. Then it is possible to freely set and cancel the master-slave relation between processors.

Title: Production of liquid crystal display device
Inventor: OSHIKAWA YASUO
IPC: G02F1/13
Filed: 1992-11-26
Abstract: PURPOSE:To uniformalize the spacing between both film substrates and to prevent the leakage of a liquid crystal from a liquid crystal injection port. CONSTITUTION:Two sheets of the film substrates 21, 22 are stuck to each other via a sealing material 28 by interposing spacers 27 consisting of resin particles therebetween. The film substrates 21, 22 are partly deflected to a projecting shape by a certain cause in this state. All the spacers 27 are nearly uniformly crushed when the two film substrates 21, 22 are clamped by a clamping member 31 and a pressure is applied thereto. The spacing between these film substrates 21 and 22 is thereby made slightly smaller than a desired spacing. The liquid crystal 36 is then injected and a sealing material 37 is disposed in the liquid crystal injection port 29. All the spacers 27 are elastically reset when the clamping by the clamping member 31 is released. The spacing between the film substrates 21 and 22 is thereby made into the desired spacing. A negative pressure is generated in the liquid crystal injection part and the sealing material 37 is sucked into the liquid crystal injection port 29.

Title: Head for magneto-optical disk device and magneto-optical disk device using the same
Inventor: TSUYUKI MITSUSACHI
IPC: G11B11/10
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To make high quality, high reliablity and inexpensiveness of the head mounted with a bias magnet for magnetizing a magnetic disk, a rising mirror installed on an optical path between a semiconductor laser light generating means and the disk and a bearing for traveling on a guide rail and other optical head constituting elements in a movable case. SOLUTION: The movable case is formed of a glass powder added thermosetting resin as a reinforced material or a thermosetting resin of a coefft. of linear expansion of around 13×10<-6> / deg.C. Thus, since the thermosetting resin case has the linear expansion coefft. smaller than an aluminum alloy about 60%, and has no anisotropy as a ratio of a linear expansion coefft. in the material flowing direction at the time of molding to a linear expansion coefft. in the direction orthogonal to this direction is 1:1, thermal stress to be generated in a rising mirror bonding part is also suppressed to a min., and bonding reliability can be enhanced by suppressing the occurrence of boundary separation and distortion of the mirror.  Then, high accurate dimensions can be obtained due to no orientation property and because a ratio of a coefft. of contraction in the material flowing direction at the time of molding and a coefft. of contraction in the direction orthogonal to this direction is also 1:1.
