Patent JP-S6221110-A (JP)
Title: Ultrasonic soldering device
Inventor: IWASA KYOICHI
IPC: G02B6/38
Filed: 1985-07-20
Abstract: PURPOSE:To prevent a fiber and an ultrasonic wave chip from abutting on each other and to dip a hollow member and the fiber in a solder bath and solder them by ultrasonic oscillation by allowing the hollow member to be inserted into the upper end surface of the ultrasonic wave chip and bringing the ultrasonic wave chip into contact with the hollow member. CONSTITUTION:The optical fiber 11 is inserted into the through hole of a connector 8 and its tip is set on a jig 14 while projecting from the reverse surface of the connector by 1-2mm. Then when the jig 14 is lowered, the connector penetrates the surface of the solder bath 1 and is inserted into the recessed part of the ultrasonic wave chip 5, so that its tip abuts on the chip. A magnet 17 operates to hold the jig and a timer 24 operates after preheating to put an ultrasonic oscillation circuit in operation, thereby applying ultrasonic oscillation from the ultrasonic wave chip to the connector, optical fiber, and solder bath. Consequently, the gap between the connector and optical fiber is charged with solder to adhere the both together.

Title: Adhered wafer and manufacture thereof
Inventor: MIURA TAKAO
IPC: H01L27/12
Filed: 1990-06-18
Abstract: PURPOSE:To prevent a wafer from chipping or cracking by chamfering the discontinuous end face of an adhered wafer and then rounding it. CONSTITUTION:An element board 11 is adhered to a supporting board 12 to form an adhered wafer 14. Then, the end face of the wafer 14 is chamfered. The board 11 is ground and polished. Thus, the discontinuous end face of the adhered boards 11, 12 is rounded to provide a rounded continuous face. Since corners to be formed by conventional sharp steps are eliminated, the wafer can be protected against cutting out or cracking.

Title: Precedingly detecting device for copy control
Inventor: KOMIYA HIDETSUGU
IPC: G05D3/00
Filed: 1983-08-31
Abstract: PURPOSE:To detect a sharply changing part on the surface of a model in advance of a stylus by providing a position control means for placing a length measuring device and a means to control the feeding speed of a tracer head in accordance with the result of the measured length by said length measuring device, in the proceeding direction of said tracer head. CONSTITUTION:A length measuring device 2 is placed at a certain length apart from axis of a tracer head 1, in the proceeding direction of the head 1, and measures the distance up to the surface of a model in advance of the head 1. A case body 5 holding the length measuring device 2 and a motor 6 is held on the outer peripheral part of the head 1, rotatably around its axis. Data of measured length from the length measuring device 2 is read in a CPU20 through an A-D convertion circuit 23 and a system bus 21 at a certain period, processed there, and stored in a memory 22. When the CPU20 detects from the data of measured length that the steepness on the model surface is above a certain level, it commands that a remaining part decelerate the copying speed through the system bus 21.

Title: Method for selectively hydrolyzing sulfate ester group
Inventor: ISHIDA KINJI
IPC: C07J9/00
Filed: 1990-06-20
Abstract: PURPOSE:To selectively hydrolyze a sulfate ester group by bringing a compound of the sulfate ester group substituted with an alcoholic hydroxyl group into contact with an activated cation exchange resin in a low alcohol solvent.

Title: Thin film magnetic head
Inventor: NAKAMURA KAZUO
IPC: G11B5/31
Filed: 1987-06-26
Abstract: PURPOSE:To easily impart optimum magnetic anisotropy to a thin magnetic film by determining the ratio of the thickness of the thin magnetic film and the pattern width in a track width direction at a specified ratio in the depth direction of a head. CONSTITUTION:The thin magnetic film 10 is so formed as to have the prescribed track width in the front end part and to be adequately broad in the rear part. The film thickness (t) thereof is so determined as to increase in proportion to the pattern width W in the track width direction, i.e., to t1/W1=t2/W2=t3/W3. Since the coeffts. of diamagnetic fields in the track width direction are thereby made the same even in any positions in the depth direction 11 of the head, the magnitude of the anisotropy to be imparted to the magnetic film attains the specified value in any positions within the pattern. The effect of a heat treatment in the magnetic field is constant within the pattern even if the magnetic film pattern with which the impartation of the anisotropy is already finished is thereafter subjected to the other heat treatment. The desirable anisotropy is thereby easily imparted to the magnetic film.

Title: Temperature measuring method for metal surface
Inventor: TAKAHASHI TAKESHI
IPC: G01J5/02
Filed: 1990-06-19
Abstract: PURPOSE:To stably and securely measure the surface temperature of metal which has a temperature gradient inside with high accuracy by performing a black dyeing treatment for the surface of the metal. CONSTITUTION:Surface dirt, sludge, etc., on a heat conduction tube 3 are removed, the black dyeing treatment is performed at a measurement position 7, and the tube thickness is measured previously. Then when a specific position is heated continuously with constant heat flux from a heating laser 1 until the external surface of the heat conduction tube 3 reaches balanced temperature, the position reaches external surface temperature determined by the heat conduction tube 3 and the heat resistance of sticking matter on its internal surface to enter a thermally balanced state and the temperature rise width is proportional to a thermal resistance quantity, so the thermal resistance quantity of a thermal resistance material 4 such as a scale is found from the difference in temperature rise width depending upon whether or not the scale sticks on the internal surface of the heat conduction tube 3. Then the black dyeing treatment does not require an error in measurement due to a heat resistance increase since the emissivity of a film is high to obtain sufficient emissivity for the measurement by a radiation thermometer and the film thickness is thin; and thickness control is not necessary because of the self-stability of the film thickness. Consequently, the stable and secure high-accuracy measurement is attained.

After removal of isobutylene and methylene chloride under reduced pressure, 70ml saline solution and 100ml ether are added thereto and the mixture is shaken. The ether layer is then recovered and this ether extraction is repeated. The extracted ether solutions are united and dried in the presence of sodium sulfate anhydride and ether is subsequently removed under reduced pressure. The resultant material is dried in a desiccator, thus obtaining the objective Fmoc-Hyp (t-Bu)-ODhbt represented by the formula.

Title: Power transmission device
Inventor: FUJIMOTO TSUTOMU
IPC: F16F15/134
Filed: 1986-07-10
Abstract: PURPOSE:To reduce noise generated by impact force caused by backlash in a change gear in idle running, by installing a tortion spring between a clutch plate and a hub in a precompressed state to provide a sufficient initial torque. CONSTITUTION:When the relative twist angle between a clutch plate 5 and the flange 7 of a hub of a device for transmitting power to a change gear is zero, a tortion spring 20 with free length l0 is placed between them previously compressed to a length shorter than the length l of a widow 21. As said tortion spring 20 is previously compressed, a sufficient initial torque can be obtained to exceed the impact force which is caused by the backlash in the change gear in idle running of an engine. In idle running, therefore, as said clutch plate 5 and said hub rotate integratedly with no relative twist between them, with an infinite spring constant, the fluctuation of the rotation of the engine is prevented from being amplified by the possible fluctuation of rotation which could be caused by the impact force in the backlashes in the change gear, the idling noise of the engine can be reduced accordingly.
