Abstract: PURPOSE:To improve the efficiency of utilizing light by providing anisotropy in the openings of the aperture part of an LCD and combining a lenticular sheet in such a manner that the direction of the large linear opening rate of the aperture part and the longitudinal direction of the columnar lenses of the lenticular sheet are in the same direction. CONSTITUTION:The anisotropy is provided in the openings of the aperture part 2 of the LCD 1 in such a manner that the linear opening rate in the vertical direction of the aperture part and the linear opening rate in the horizontal direction thereof vary. In addition, the lenticular sheet 10 is combined with the LCD 1 in such a manner that the direction of the large linear opening rate of either the vertical or horizontal direction and the longitudinal direction of the columnar lenses of the lenticular sheet 10 are in the same direction. Thus, the projected light is focused to the aperture part by the condensing effect of the columnar lenses of the lenticular sheet 10. The efficiency of utilizing light is thus greatly improved even when the opening rate (area rate) is the same as the opening rate of the conventional LCD.

Title: Semiconductor-element cooling device
Inventor: MAEHATA TERUAKI
IPC: F25B21/02
Filed: 1992-11-10
Abstract: PURPOSE:To prevent the deterioration of cooling efficiency beforehand and to improve assembling workability by forming a mounting stage for fixing an optical semiconductor element and an arranging state for arranging a light transmitting means, which is connected to the optical semiconductor element, together with the cooling-side insulating plate of an electronic cooling unit as a unitary body.

When electric power is supplied into an electronic cooling unit U through a lead wire 5, the insulating plate 1 is cooled, and heat is dissipated from the side of an insulating plate 2. The optical semiconductor element 6 is cooled through the mounting stage 7a, which is formed as a unitry body with the insulating plate 1. At the same time, the heat is dissipated to the outside through a receiving stage 18 and a heat sink device 9, which are formed as a unitary body with the insulating plate 2. Thus, the deterioration of the heat dissipating efficiency can be prevented, and the assembling-work efficiency can be improved.

Title: Apparatus and method of link transfer
Inventor: JIYON UIRIAMU AAUIN
IPC: H04L1/00
Filed: 1989-12-15
Abstract: PURPOSE: To enable transfer without introducing random disparity error by forwarding one character if the disparity result on an idle character which is generated at the time of the final character transfer in a frame does not agree with that of the final character in the frame. CONSTITUTION: A particular sequence generator 3 alternately agrees the disparity idle before frame transfer, and transmits this code to a serializer 30 via an OR gate 5 and bus 7. Data is allowed to flow into a character encoder 4 from a control logic 21 through a selector 18. All data words is transferred and then the reminder of frame information having a CRC and an EOF characters is encoded and the encoded data is transferred to the serializer. Then, the succession of idle characters to be transmitted to the serializer 30 until the other frame is to be transferable is permitted. The status change of a flip flop 2 is avoided by that a bypass line 29 only for one cycle is given by the character encoder 4.

IPC: E04F15/02
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To improve waterproofness to the lower structure of a vestibule when the vestibule is installed to a second floor section. SOLUTION: The lower frame 8b of a vestibule sash 8 for a vestibule 3 is connected onto the external surface of a dwelling house in the lower section of the vestibule 3 by a mounting piece 8c without being directly joined with a structure on the lower side. Consequently, the transmission of moisture to the lower structure by nails, etc., for connecting the lower frame 8b can be prevented in an inferior drainage section on the lower side of the lower frame 8b of the vestibule sash 8. A section extending over the external surface of the dwelling house from a sill 4 in the vestibule 3 is covered with an integral waterproof sheet 21. Accordingly, the covering of the side edge of the waterproof sheet 21 in the inferior drainage section on the lower side of the lower frame 8b can be prevented.  The transmission of moisture to the lower structure from the side edge of the waterproof sheet 21 can be obviated.

Filed: 1990-11-27
Abstract: PURPOSE:To improve the transfer efficiency of an unmanned carrier by adjusting the guide width of a station serving as a subject of transfer as well as the guide width of the carrier to the value accordant with the size of a transfer object this object is loaded on the unmanned carrier. CONSTITUTION:A transfer command 6 given from a ground control panel 2 is sent to an unmanned carrier 4 which is kept waiting at a home station 30 and the station 31 and 32 serving as the subject of transfer. The guide widths of the guides 17a and 17b of the unmanned carrier 4 are adjusted by a guide width adjustment mechanism to the value accordant with the type of a transfer object 13 while the unmanned carrier 4 is traveling. At the same time, the guide widths of the guides 121a and 121b of both stations 31 and 32 are adjusted to the value accordance with the type of the object 13 respectively. In such a way, the adjustment of width is completed during the running of the unmanned carrier 4 in regard of all guides of the AGV 4 and the stations 31 and 32. Thus the apparent guide width adjusting time is equal to zero and the transfer efficiency is improved for the unmanned carrier 4.

Title: Parking device of automatic transmission
Inventor: KAMINAGA SEIJI
IPC: F16H59/10
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal sound to be generated caused by the contact to a parking ball. SOLUTION: When a select lever is selected into the parking range during traveling of a vehicle, a parking rod 32 is moved to a parking ball 24 side, a wedge 30 fixed on one end of the parking rod tends to press the parking ball. However, a parking bear is rotated at high speed, and a claw part of the parking ball is not advanced to a parking gear. Accordingly, the wedge is moved together with the parking rod in such a direction as to be separated from the parking ball while compressing a coil spring. Therefore, the wedge and the parking rod are separated from the parking ball, no member for generating abnormal sound caused by the contact to the parking ball exist, and a sense of incongruity is not given to a driver.

Abstract: PURPOSE:To improve the stability of connection and the stability of work by pushing a lead frame, from which a plurality of terminal sections are removed, and the slant face section of a chamfering section in a resin seal member by two members from upper and lower sections. CONSTITUTION:A member 13 for hold-down fixes a resin seal member 11 to a shape along the slant faces of chamfering sections in the resin seal member in four chamfering sections 15 in the resin seal member 11. Since such constitution is sandwiched by clamps 16, the resin seal member 11 and a lead frame 12 are not moved relatively, the lead frame is not bent and no warpage is generated due to deflush, and the positioning properties of frames at the time of automatic conveyance are also stabilized. The shapes of terminal forming, etc., are also equalized. Flatness after forming is also improved, and the stability of connection and workability at the time of soldering to a printed substrate are enhanced.
