Title: Optical signal transmission system
Inventor: YOSHIDA TOMOHIKO
IPC: G02B6/42
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To realize an optical transmission at a high speed by a simple optical system while maintaining a high coupling efficiency as it is. SOLUTION: By using a LED, made of InP, easy to modulate at high speed and having a central light emitting wavelength of 1.31μm for a semiconductor light emitting element as a photo-electric converter, a plastic clad fiber(PCF) 24 whose angle of light receiving visual field is large, about 0.4, being currently in practical use and an optical system whose numerical aperture on the side of PCF 24 is <=0.3 for a coupling optical system, a high-speed modulated signal having a transmission velocity >=100Mbps is transferred longer than 1km under the condition that light emerged from the LED 21 is efficiently coupled to PCF 24. Consequently, in an intermediate distance region in which a communication distance is about 1km, since an optical system with a large price structure ratio is made inexpensive, an inexpensive system is constituted without lowering the transmission speed.

Title: Reflection type liquid crystal display device
Inventor: TAKEDA MAMORU
IPC: G09F9/30
Filed: 1989-03-17
Abstract: PURPOSE:To easily flatten the surface of a reflection type liquid crystal display picture element and to improve contrast ratio by interposing an insulating layer between a 1st picture element electrode which is connected to a drain electrode and a 2nd picture element electrode which is a reflection electrode. CONSTITUTION:The 1st picture element electrode 7 is connected to the drain electrode 4 and the 2nd picture element electrode 9 which is the reflection electrode is electrically connected to the 1st picture element electrode 7 through the flattening insulating layer 8 by capacitor connection. By using an organic material such as polyimide, etc., for the flattening insulating layer 8, at such a time, the unevenness of a lower part is mitigated and easily flattened. Besides to that, since the 2nd picture element electrode 9 and the 1st picture element electrode 7 are connected by the capacitor connection, the flat surface of the flattening insulating layer 8 reflects on the 2nd picture element electrode 9, thereby easily flattening the surface of the 2nd picture element. Thus, the reflection picture element is easily flattened and an adverse effect that nonuniformity occurs in the voltage and brightness characteristic of liquid crystal in the picture element is reduced, so that the contrast ratio is improved.

Abstract: PURPOSE:To easily manufacture a highly practical dielectric separating substrate in which a semiconductor separating island with buried layer and semiconductor sepa rating island without buried layer coexists by making the thickness of the oxide film partially coating the surface of the island without buried layer thinner than that of the oxide film partially coating the surface of the island with buried layer.

By etching the oxide films 2 and 3, the thin film 3 is completely removed, but the thick film 2 is not completely removed, but left to some extent. Then, by performing anisotropic etching, the layer 12 is removed from the part for the semiconductor separating island without buried layer, but is left as a buried layer 13 at the part for the semiconductor separating island with buried layer. Then a desired dielectric separating substrate is obtained by successively forming and polishing an insulating layer 7 and polycrystalline silicon layer 18.

Title: Flush toilet structure
Inventor: SUZUKI YOSUKE
IPC: E03D11/02
Filed: 1994-03-11
Abstract: PURPOSE:To provide a washing force sufficiently cleaning the face of a toilet bowl, by forming an opening step slantly rising upward from the front guide wall to the rear guide wall of the four peripheral sides of the opening. CONSTITUTION:Steps 41 formed at the right and left guide walls 38 is shaped to slantly rise at a specified able from the short side of the front guide wall 37 to the rear guide wall 39 and the steps 41 of the rear guide wall 39 side is formed higher than the end of the front guide wall 37. The washing water supplied from a low tank through a water supply hole 35 is conducted from feed water path 33 to a division chamber 34. Since the height H1 of the front wall 34a side of the division chamber 34 is formed higher than the height H2 of the top position of a trap 55 with an almost reversed U-shape in the feed water path 33, the impulsive force of the flushing water from the feed water path 33 against the front wall 34a is dampped. And hence, the resistance of water is reduced and involution of air is remarkably reduced. And the stream speed of washing water from a washing waver opening 47 of the rim water path 45 becomes favorable to provide a washing force sufficiently cleaning the face of a toilet bowl 36.

IPC: G01M10/00
Filed: 1985-03-30
Abstract: PURPOSE:To execute the vibration experiment in the condition similar to the reality for the underwater construction by linking the static part at both sides of the vibration part with a flexible joint. CONSTITUTION:When a vibration stand 11 is vibrated as shown by an arrow mark X, a vibrating part 16 and a model 4 are vibrated, side walls 17a and 18a of static parts 17 and 18 are stationary as it is, and therefore, the horizontal wave motion of water 2 due to the side walls 17a and 18a will not occur. Consequently, accordingly to the water tank 15 for vibration experiment, the earthquake-resistant experiment of the underwater construction can be made in the condition close to the real condition. Since the section between the vibrating part 16 and the static parts 17 and 18 is linked by flexible joints 19 and 19, the static parts 17 and 18 will not vibrate even when the vibrating part 18 vibrates, and the leakage of the water from those joints can be prevented.

Abstract: PURPOSE: To prevent seizure, damage and the like of the inside of the cylinder by forming a piston, a piston rod and cushion bosses on the head and rod side monolithically and thereby softening surely the cushion in advancing and retreating strokes.  
     CONSTITUTION: The rod-side cushion bosses 15a and 15b having projected outer periphery, the piston 15c and the head-side cushion boss 15d are formed monolithically in the rod part of the piston rod 15 sliding inside the cylinder 11. Moreover, a rod-side cushion bore 16a is formed by providing a circular convex part 16 inside a rod cover 14. When the piston rod 15 is made to advance by the fluid from an inlet-outlet port 19, deceleration is made owing to the difference in pressure caused when the cushion boss 15a is pressed in the circular clearance of the cushion bore 16a, whereby the cushion is relieved. Next, deceleration is made also when the cushion boss 15b passes through the cushion bore 16a, whereby the cushion is further relieved.

IPC: G03B23/02
Filed: 1985-04-01
Abstract: PURPOSE:To remove a slack from a web regardless of the feed direction of the web and to make no flaw in a web and prevent an error in retrieval by applying a brake to rotating shafts on a web take-up side and a web supply side after reversing the rotating shaft on the web supply side. CONSTITUTION:A coincidence signal outputted by a comparison part 34 is sent to delay circuits 40 and 41 and then the 1st and the 2nd brake devices 20 and 21 are driven after delay times of the delay circuits 40 and 41 to stop a film. Thus, the rotating shaft of a film supply side cartridge 1 is reversed slightly, so the film F is tensed slightly and stops without slackening. A forward feed motor 18 is freed from its drive when the coincidence signal is sent and a take-up reel tends to keep on rotating because of the inertia of the forward feed motor 18 and a take-up shaft, but is stopped immediately by the brake device 21.
