Title: Method of molding resin item
Inventor: OBARA HIFUMI
IPC: B29C33/00
Filed: 1982-07-05
Abstract: PURPOSE:To obtain easily a resin molded item of a desired shape without requiring any complicated means with the loading operation of the resin quite ready, by using a mold of a configuration memory alloy. CONSTITUTION:The mold is made of a configuration memory alloy, the mold is formed into an intended shape to which an item is to be molded, and the shape is memorized. For instance, a channel-shaped mold 1 of a configuration memory alloy having a groove 2 in the center is formed into an L-shape. When a resin is to be molded, the mold is plastically deformed at normal temporatures or low temperatures, and after the resin material 3 is loaded into the groove 2, the mold is heated to a prescribed temperature to regain the memorized configuration thereby to obtain the intended item. The heating is carried out at a temperature (e.g. 100-900 deg.C) at which the resin material to be molded is softened and the configuration memory alloy can regain the memorized configuration, and if the heating is carried out at 500 deg.C or above, it is carried out under an atmosphere free of oxygen so as to prevent oxidation. The mold can be employed repeatedly.

Abstract: PURPOSE:To reduce the diameter of a balloon without generating pleats during the insertion or discharge of the catheter into or from a blood vessel at the time of a treatment by reinforcing the balloon with composite yarn consisting of elastic yarn and non-elastic yarn having the free length larger than the free length of the elastic yarn. CONSTITUTION:The balloon 2 is reinforced with the composite yarn consisting of the elastic yarn and the non-elastic yarn having the free length larger than the free length of the elastic yarn. The expandability and contractability of the balloon of even the catheter with the balloon having a large expansion diameter in cardio-valvulotomy, etc., are large and, therefore, the outside diameter of the balloon can be reduced by using the catheter with this balloon. The catheter is inserted into the blood vessel by a simple Seldinger method. The smaller incision for the treatment is, therefore, necessitated and the treatment and management after the operation are simple. The time to the healing is extremely fast. Pushing forward of the balloon 2 down to the affected part in the blood vessel or the cardial cavity is executed by the easy operation, such as by entraining a guide wire or the inflated balloon in blood flow.

Title: Surface acoustic wave filter
Inventor: SHIMAKAWA JIYOUJI
IPC: H03H9/25
Filed: 1978-09-22
Abstract: PURPOSE:To obtain the filter having a plurality of narrow band pass bands with a single element, by constituting the reflection loop on the delivery line of surface acoustic wave on the surface of piezoelectric substance.

Title: Digital audio signal processing unit
Inventor: KAKU JUNYA
IPC: H03H21/00
Filed: 1993-05-19
Abstract: PURPOSE:To suppress intermittent sound or noise by dividing a voice signal in frequency bands and driving speakers arranged at positions corresponding to sound image localizing positions so as to let the position of sound image localization for a listener be constant thereby eliminating the need for a speaker selector switch. CONSTITUTION:A voice signal is given to an A/D converter through an LPF 1, and the converted signal is inputted to a signal processing section 3, in which the signal is divided into plural frequency bands and sound image localization position information and voice signal information data D are obtained through arithmetic operation processing and they are added at every sort of the same sound image localization position data and the result is inputted to a speaker drive section 4. The drive section 4 selects a correspondent D/A converter section by a selecting signal CSK obtained by decoding the information D based on a conversion tape to obtain a voice signal and drives a speaker corresponding to the sound image localized position. Thus, the sound localized position is unchanged and becomes constant independently of the position of the listener, no speaker selection switch is required and intermittent sound or noise due to the presence of the switch is reduced.

Title: Liquid crystal optical switch
Inventor: TANEI HEIKICHI
IPC: G02F1/1347
Filed: 1986-05-23
Abstract: PURPOSE:To switch traveling directions of light according to whether or not there is a low driving voltage by arranging one liquid crystal cell which has a twisted array when applied with no voltage or an homeotropic array when applied with a voltage between two liquid crystal cells which are put in a homogeneous or homeotropic array. CONSTITUTION:A liquid crystal layer 16 reflects P polarized light, but S polarized light is transmitted through the liquid crystal layer 16 to reach a bevel surface of semitrapezoid prismatic glass 9, and reflected by the bevel and converged by a lens 5 to reach a projection optical fiber 4. When a voltage 3V is applied to the liquid crystal layer 17 of a twist array liquid crystal cell, liquid crystal molecules except liquid crystal molecules very near glass plates 10 and 11 are oriented (in hometropic array) at right angles to the glass surfaces. Light passing through the liquid crystal layer 17, therefore, does not has the vibration direction rotated and reaches the projection optical fiber 3. Light incident from an incidence optical fiber 2 is the same. Namely, when the low voltage of about 3V is applied, light beams of incidence optical fibers 1 and 2 reach projection optical fibers 3 and 4, thus constituting a 2X2 optical switch.
