Title: Method for heat treating steel pipe for car body reinforcement
Inventor: IWASAKI TOSHIO
IPC: C21D9/08
Filed: 1991-10-22
Abstract: PURPOSE:To provide a steel pipe having high dimensional accuracy, particularly in outer diameter and in roundness, even after quenching a preformed pipe by executing pre-heat treatment to it before quenching the preformed pipe of the steel pipe for a car body reinforcement. CONSTITUTION:Before the preformed pipe of the steel pipe for the car body reinforcement is quenched, this pipe is heated to 450-1050 deg.C and after holding for 5-30min, this pipe is cooled and thereafter, the quenching is executed. At the time of quenching the preformed pipe subjected to no pre-heat treatment, the dimensional accuracy of the outer diameter and the roundness thereof is remarkably degraded, but at the time of applying the pre-heat treatment, the outer diameter and the roundness nearly equal to those of the preformed pipe, are obtd.

Abstract: PURPOSE:To enable correction repeatedly even when regaining a desired shape is impossible by one operation by a method wherein a paste-like photosetting resin is applied in a desired shape at a part to be repaired of a dental technician's working model and then, the paste-like photosetting resin is irradiated with a light beam to harden. CONSTITUTION:A specified amount of a paste-like photosetting resin 3 is applied on a broken member 2 of a tooth part 1a of a dental technician's working model 1 broken partially to make a specified shape. Then, the paste-like photosetting resin 3 is irradiated with a light beam using a light beam irradiator 4. The light beam irradiation conditions varies with the type of lamps of the light beam irradiator 4 and as standard, the lamps of 85-1,300w, an irradiation distance of 1-5cm and irradiation time of about 90-300sec are preferable. As a result, the paste-like photosetting resin 3 is hardened to accomplish the repairing of the broken part 2. This enables the finishing of the part to be repaired to a desired shape.

Title: Optical switch
Inventor: AJISAWA AKIRA
IPC: G02F1/015
Filed: 1986-11-17
Abstract: PURPOSE:To realize a low voltage and a high quenching ratio by applying vertically an electric field in the layer direction of a multiple quantum well structure by a quantum well structure in which the first semiconductor whose thickness is about a de Broglie wavelength and whose layer thickness is within a specific range is inserted and held by the second semiconductor layer. CONSTITUTION:A characteristic of an optical switch is improved by setting an increase of an absorption coefficient caused by shifting to a long wavelength side of an absorbing end of a multiple quantum well (MQW) structure by applying an electric field, as an operation principle. That is to say, a light beam of a long wavelength side is made incident from an absorbing end of an MQW guide layer 4 of a multiple MQW structure having multiplexly in the layer thickness direction an MQW structure in which a first semiconductor layer whose thickness is within a range of >=120Angstrom  of about a de Broglie wavelength is inserted and held by a second semiconductor layer whose band gap is wider than that of the first semiconductor layer. In such a state, when a reverse bias is applied between electrodes 7, 8 vertically in the layer direction, an absorption corresponding to the applied electrode is generated in the MQW layer, the waveguide light is absorbed in the MQW, not emitted from an output terminal, and the optical switch goes to an OFF state.

Title: Telephone exchange
Inventor: TOKUDA TOMOHIRO
IPC: H04M3/00
Filed: 1988-10-31
Abstract: PURPOSE:To decrease the call waiting states by connecting a calling request received from a telephone terminal to an idle facsimile circuit in case all designated telephone circuits are busy and a designated facsimile circuit is not busy. CONSTITUTION:A trunk of a facsimile equipment F contains a changeover switch circuit 1A which is properly connected to N pieces of trunks TP. In case L sets of telephone circuits 3P are all busy and a facsimile circuit 3F connected to the equipment F is not busy, a telephone PN having a new calling request is connected to the circuit 3F. The equipment F generally contains an automatic transmission means. As a result, the occurrence of troubles can be suppressed even though the designated trunk line of the relevant equipment F is temporarily used to a telephone via the process. Thus it is possible to decrease the call waiting states of the telephone circuits and to improve the communication efficiency.

Abstract: PURPOSE: To obtain a noise filter generating no error even when the frequency of noise fluctuates by providing a trigger generator generating a trigger signal in the timing corresponding to the cycle of the noise contained in an analogue signal. CONSTITUTION: An A/D converter 1 converts an analogue signal (a) to a digital signal (d) to output the digital signal to the shift register 31 of a running average calculation means 3.

Once the window position where the maximum energy is obtained has been found, a DFT window position is so set that the head of the window is positioned at the window position, and a DFT window signal is generated. Then it is inputted to a Fourier transforming/differential decoding part 66.

Filed: 1989-10-25
Abstract: PURPOSE:To reduce the power consumption by locking a magnetic head in a stop state by a permanent magnet of a voice coil motor, when the magnetic head is attached to a swing arm and is stopping at a prescribed position by a stopper member. CONSTITUTION:When a magnetic head 38 is positioned in the innermost periph ery of a disk 39, one end of the outside peripheral part of a coil 34 abuts on a stopper member 42 and a movement of the head 38 is in a stop state. In this case, a magnetic member 41 attached to a swing arm 31 through a member 40 is attracted by a permanent magnet on this side of a voice coil motor 33. As a result, the force in the inside peripheral direction of the disk 39 works on the arm 31, and the coil 34 being in the end part of the arm 31 is pushed against the stopper member 42. By this pushing force, the stop state of the movement of the head 38 is locked. In such a way, a lock mechanism can be obtained easily and at a low cost.

Title: Ink-cartridge for ink-jet and production thereof
Inventor: ISHINAGA HIROYUKI
IPC: B41J2/175
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To make an ink cartridge larger and complicated in shape easily with the smallest number of components, by welding and integrating the wall of an ink storage compartment and one surface of a lid by frictional heat produced by vibration. SOLUTION: A lid 3 is set in an upper jig and a container 2, of which an ink cartridge is composed, is set in a lower jig. During a welding process, the upper jig is vibrated with the container 2 and lid 3 being in contact with each other. Consequently friction occurs at a joint 5 between the lid 3 and container 2, and the lid 3 and container 2 melt by frictional heat produced at the time. The upper jig presses the lid 3 to the container 2 at specific pressure, and with progress of melting the lid 3 and container 2 are welded together to a specific positional relationship. The vibration stops after the welding proceeds to the specific position and, in this condition, the temperature of the welded part decreases, and the jigs are fixed in the positions until they are resolidified. It is preferable that the vibration be set to 100-500Hz, in order to make the process more stable.
