Title: Surface acoustic wave device
Inventor: YANAGIHARA HITOSHI
IPC: H03H9/145
Filed: 1982-02-22
Abstract: PURPOSE:To eliminate the dissidence of propagating distance and to obtain good frequency characteristics, by dividing an IDT electrode into two parts on the basis of the propagating center axis of a surface acoustic wave obtaining coincidence between SAW propagating center axes even in case plural inputs or outputs exist. CONSTITUTION:An input IDT electrode 1 and ouput IDT electrodes 2, 3B and 3B are provided on a piezoelectric substrate 7. For the electrode 2, the propagating center axis of surface acoustic wave of the electrode 2 is coincident with that of the electrode 1 and these center axes are shifted in parallel toward the electrode width. The electrodes 3B divide the output electrode into two parts centering on an SAW propagating center axis 6 and hold the electrode 2 between them. In such a way, the electrodes 1, 2 and 3B are distributed so as to obtain coincidence among axes 4, 5 and 6. As a result, the propagating distance from the input IDT through the output IDT is symmetrical centering on the center axis. This process eliminates the discordance of the propagating distance.

Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To lessen the dependence of the optical characteristics of a waveguide element on external environmental temperature by mounting a temperature sensor to a place where an array waveguide exists by using a thermosetting silicone resin based adhesive having a specific Young's modulus. SOLUTION: This optical module has the waveguide element 1 which is housed in a casing having a thermally insulating structure and has the optical characteristics dependent upon temperature, a heater for controlling the temperature of the waveguide element 1 and the temperature sensor 4 for detecting the temperature of the waveguide element 1. The desired optical characteristics are held by controlling the temperature of the waveguide element 1 constant by using the heater and the temperature sensor 4. The temperature sensor 4 is mounted at the place where the array waveguide 2 of the waveguide element 1 exists by using the thermosetting silicone resin adhesive having the Young's modulus of <=1 kg/mm2. When the adhesive having the large Young's modulus is used, thermal stress acts on the array waveguide 2 and the desired optical characteristics are no longer obtainable.  Then, the thermal stress effect of the adhesive on the array waveguide may be resultantly reduced.

Title: Packet transmission control system
Inventor: TAZAKI TAKASHI
Filed: 1985-02-15
Abstract: PURPOSE:To transmit a retransmission packet in a short time with simple processing by using a reception busy field to inform the disabled reception of a sender communication controller when no packet is received because no idle reception buffer memory exists, allowing the sender communication controller receiving the notice to reset the reception busy field of the packet and transmit it as a transmission packet. CONSTITUTION:Even when a branching/insertion control section 7 identifies that a reception packet (a) is effective and addresses to the own device, if an unreceivable signal (c) is added, the section 7 sends the packet not received while setting the reception busy field BY as busy. The sender communication controller discriminates that the packet is a packet not received by a destination communication controller, resets the reception busy field BY and sends the packet to a transmission line from an output terminal 11 via selector 4 as it is.

Abstract: PURPOSE: To prevent the floating up of a control rod, by means of setting up a cam at the head part of a control rod, and of allowing a control rod stopper installed in the guide tube to be interfered.  
     CONSTITUTION: A spring is fixed on a pin 10 and a cam 11 by means of allowing the cam 11 to be supported by the pin 10 by welding the pin 10 at the head part of a control rod. A stopper 14 is set up at the opening port part of the head part 7, thereby the end of the cam 11 is prevented from entering into the innerside of the head part 7. And a control rod stopper 15 is set up at a guide tube 4. For the separation of an elongated tube 5 and the heat part 7 of the control rod, the head part 7 of the control rod is released from the gripping mechanism by means of allowing a finger rod 9 to be lowered downward by a driving mechanism. When the finger rod 9 is rising, the cam 11 rotates around the pin 10, thereby the top is projected from the opening of the head part 7. When the control rod is intended to float up by a liquid pressure, the floating can be prevented by means of interfering the cam 11 by the control rod stopper 15.

IPC: A61G5/02
Filed: 1990-02-06
Abstract: PURPOSE:To perform safely ascent and descent of a sheat by connecting together each proper part of a front link and a rear link with a compression spring. CONSTITUTION:When a rider grasps a grip 6a of a handle with a right hand and takes off a handle lever 6 from a stopper 8a and pulls the grasp upward, a front link 3 and a rear link 4 are each rotated in the left hand side as the distance between O5 and O7 becomes shorter and a sheat 2 is lowered. The grip 6a is furthermore pulled upward, the sheat 2 is lowered close to the floor level and under this condition, when the level is hooked on a stopper 8b, the sheat 2 is fixed and the rider can safely get on and off. In addition, when the level is taken off from the stopper 8b and the grip 6a is lowered, the sheat 2 is elevated as the distance between the link 3 and 4 becomes larger. In addition, a compression spring 7 always provides a force which tends to widen the distance between the links 3 and 4 in such a way that the sheat is prevented from sudden lowering caused by the weight of the rider.
