Patent JP-H0817989-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: OKA HIROTAKE
IPC: H01L23/50
Filed: 1994-06-28
Abstract: PURPOSE:To increase the heat dissipation as the whole transistor array with a heat dissipation plate while the wear of a molding die and an increase in the cost of the transistor array with the heat dissipation plate are inhibited by a method wherein a resin insulating layer part interposed between tubs bonded to semiconductor pellets and the heat dissipation plate is formed of a high-heat conduction resin material. CONSTITUTION:When a transistor array 10 with a heat dissipation plate operates on a printed-wiring board 62, pellets 12 generate heat. The heats of these pellets 12 are conducted to the heat dissipation plate 22 via tabs 7 and a resin insulating layer part 17 and are dissipated to the exterior through the plate 22. At this time, the layer part 17 is formed using a high-heat conduction resin material and at the same time, is closely adhered completely to the tabs 7 and the plate 22. Moreover, as the thickness of the layer part 17 is made very thin, the heats from the tabs 7 are conducted very effectively to the plate 22. As a result, the heat dissipation as the whole transistor array 10 with the heat dissipation plate can be improved.

Abstract: PROBLEM TO BE SOLVED: To perform a proper abnormality diagnosis by stopping except an elevator diagnosed, extracting only a sound of the diagnosed elevator, frequency-analyzing the extracted sound, and comparing this value with a normal value of frequency analysis in the initial period of operating the elevator. SOLUTION: Whether an elevator is in operation or not is decided, to stop except the elevator diagnozed, to extract a sound of the diagnosed elevator, and to measure a temperature in the periphery of a sound detecting device. The extracted sound is frequency-analyzed by a frequency analyzing means 11, to be decided for whether a value of the initial time or not, and to be stored as a normal value in a normal value memory means 12 when the value is in the initial time. A value frequency- analyzed in the second time after is compared with the normal value in a comparing means 13. An abnormality diagnosis is performed by using the compared value and a measured temperature. When a result of performing the abnormality diagnosis is decided within a permissible range in a decision means 14, operation is continued, to be decided for whether an important location or not in the case of exceeding the permissible range, and a trouble signal is output to the outside by a transmitting means when decided an important location, to stop operation. When not decided an important location, whether operation can be performed or not is decided.

Title: Ink jet head and manufacture thereof
Inventor: SASAKI TSUTOMU
IPC: B41J2/055
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To improve the assembling efficiency and joining quality in a head by a method wherein a filmy adhesive is applied for the joining of a liquid chamber supporting member onto a board, on which slit grooves are formed. SOLUTION: A board 11 and a frame member 13 are joined together through an adhesive 14. As the adhesive 14, a filmy adhesive is used. As the filmy, adhesive, an epoxy-based filmy adhesive is preferable from the view points of water resistance, heat resistance joining strength and the like. Since the filmy adhesive is produced by bringing a liquid resin adhesive into a B stage (semi-hardened state), the lowering of the viscosity the adhesive due to the heat of hardening at its hardening is suppressed to a comparatively few. Further, as for the resinous material of the filmy adhesive, a material containing 1,000 or more oligomers is used in order to reduce the fluidity of the adhesive so as to allow to lower its viscosity more.

IPC: H03B5/30
Filed: 1988-07-08
Abstract: PURPOSE:To execute an automatic return in case a lock has been disconnected by providing a second phase lock loop in a main phase lock group in addition to a main phase lock loop and inputting an output from the second phase lock loop to the main phase lock loop. CONSTITUTION:The title device is provided with a first phase lock loop(PLL) 30 for tracking a resonance point, which controls a driving frequency of an ultrasonic vibrator, based on a phase difference between a voltage applied to an ultrasonic vibrator and a flowing current, and a second PLL 20 which is provided in the first PLL in addition to the first PLL 30 and whose output is inputted to the first PLL. A free-running oscillation frequency of the second PLL 20 is set to the vicinity of a resonance frequency of the vibrator, and its lock range is set to a narrow one to the extent that it is below a sub- resonance frequency of the vibrator. In such a way, even if a lock for tracking a fundamental resonance point by the first PLL 30 is disconnected, a tracking operation of the fundamental resonance point by the first PLL 30 is restarted by a free-running oscillation output of the second PLL 20, therefore, the ultrasonic vibrator can always be driven by the fundamental resonance point.

Title: Electromagnetic ultrasonic wave applied measuring device
Inventor: SANEMORI AKIRO
IPC: G01N29/04
Filed: 1984-08-16
Abstract: PURPOSE:To measure even a material which has large magnetic hysteresis by producing a bias magnetic field by an AC magnet and demagnetizing the object material when it moves away from a measurement position. CONSTITUTION:The AC magnet 7 is excited by an AC power source 8 to produce magnetic flux which is phi delayed in phase behind the voltage of the power source 8. A controller 9, on the other hand, generates and sends a pulse to a pulser receiver 3 when the density of the generated magnetic flux exceeds a specific value phi1+phi2 after the zero-cross point of the voltage of the power source 8. Then, a pulse current flows through an eddy current generating and detecting coil 2 to generate an eddy current on the object material 1, generating an ultrasonic wave. This ultrasonic wave propagates in the object material 1 and is reflected by its back surface to generate an eddy current on the surface, and the eddy current is detected by the coil 2. The thickness of the object material 1 is measured from the time from the pulse generation to the detection. The object material 1 after being measured is demagnetized when the coil 2 moves away, and then there is no residual magnetism left, so that even a material having large magnetic hysteresis is measured.
