IPC: H03H9/19
Filed: 1987-05-16
Abstract: PURPOSE:To reduce the oscillating level of anharmonic oscillation and to improve workability, by forming a waveguide in the propagating direction of the anharmonic oscillation, and setting the cut-off frequency of the waveguide higher than a main oscillation frequency and less than an anharmonic oscillation frequency. CONSTITUTION:A crystal piece 1 is constituted by cutting in a disk shape by AT cut, and extending draw-out electrodes 4 and 5 having width (b) on the outer peripheral parts of both ends in a direction of axis Z' from driving electrodes 2 and 3. In such a case, the cut-off frequencies of the crystal piece 1 itself, the electrodes 4 and 5, and the crystal piece 1 on which the electrodes 2 and 3 are formed are assumed as f1, f2, and f3. And assuming the width of the electrodes 4 and 5, and the electrodes 2 and 3 as constant, the frequency arrangement of each of the frequencies f1, f2, and f3 is expressed as f1>f2>f3 by a mass load effect. Therefore, the confinement areas DELTAf1 and DELTAf2 of a driving electrode part 8 and a draw-out electrode part 7 are set between the frequencies f1 and f3, and the frequencies f1 and f2, respectively. Consequently, the anharmonic oscillation fs' being positioned between the frequencies f1 and f2 and whose propagating direction is set in the same direction as that of the draw-out electrode part 7 is propagated setting the draw-out electrode part 7 as the waveguide.

Abstract: PURPOSE:To improve volume efficiency as well as charging/discharging cycle performance by binding positive electrode active material particulate with a conductive high polymer, and by using an active material having a reduction electric potential nobler than an out-of-dope electric potential of the conductive high polymer. CONSTITUTION:LiCoO2 particulate serving as a positive electrode active material is applied to a collector body made of aluminium by pressing, and a positive electrode is manufactured. The positive electrode is soaked in LiClO4 in which pyrrole is dissolved and propylene carbonate solution, while by using lithium for an opposite electorde, voltage of 3.3-3.5V is applied thereto. Polypyrrole which is P-doped in such a way that LiCoO2 particulate is surrounded thereby is thus synthetized, and the LiCoO2 particulate is bonded on the collector body through the polypyrrole. The LiCoO2 has a reduction electric potential nobler than the electric potential of the P-type out-of-doping of the polypyrrole.

Filed: 1990-05-08
Abstract: PURPOSE:To eliminate the generation of a photoelectromotive force in an integrated circuit, to prevent a difference in contrast from being generated, and to improve the display quality by fitting an electric insulating light shield member to the integrated circuit previously. CONSTITUTION:The electric insulating flat light shield member 6 of, for example, vinyl chloride is fitted previously to the bare chip 2 of the semiconductor integrated circuit by using an adhesive 26. In this state, the terminal 8 of a liquid crystal element 7 and the bump 3 of the bare chip 2 are connected electrically through an anisotropic conductive adhesive layer 9. Therefore, the integrated circuit is prevented through the operation of the light shield member 6 from being irradiated with natural light and indoor light and no photoelectromotive force is generated in the integrated circuit. Consequently, the contrast of a liquid crystal element does not have a difference owing to the photoelectromotive force and the display quality can be improved.

Title: Photoconductive element and manufacture thereof
Inventor: HASHIMOTO JUNICHI
IPC: H01L29/20
Filed: 1991-05-24
Abstract: PURPOSE:To enable a photoconductive type photodetective element to be en hanced in response speed by controlling the mobility of positive holes inside a light absorbing layer. CONSTITUTION:A photoconductive element 10 is provided with a light absorbing layer where quantum well layers 5 which contain compression distortion and barrier layers are alternately laminated. Carriers generated by incident light are taken out from both the ends of the light absorbing layer and a substrate 6. In the photodetective element 10, compression distortion is contained in the quantum well layers 5. Therefore, positive holes of large effective mass (heavy positive hole) out of carriers which are conducted through the quantum well layers 5 are lessened in effective mass along the plane direction of the well layer and enhanced in mobility as affected by compression distortion induced in the layers 5. In result, a photoconductive element can be enhanced in response speed.

Title: Measuring method of flow rate of molten metal
Inventor: KANAMORI KIYOSHI
IPC: G01F23/28
Filed: 1990-05-10
Abstract: PURPOSE:To measure the flow rate of a molten metal by a method wherein light beams are projected towards the surface of the molten metal from a light emitting device, the reflecting light is received by a photoreceptor, and the position of the surface of the molten metal is detected. CONSTITUTION:A flow rate measuring apparatus is comprised of a weir 7 provided at a predetermined position of a tub 4b, a level detector 8 provided above the weir 7 at the side of the upper stream of the weir 7 and an operating device. The level detector 8 consists of a light emitting device 9 which generates laser beams, and a photoreceptor 12 which guides the reflected laser beams to an image sensor 11 thereby to detect an angle of incidence. The laser beams from the light emitting device 9 are reflected at the surface of the molten metal, and enter the photoreceptor 12 with an inclination of theta to the vertical line. However, since the molten metal is flowing and the surface is billowing, the reflecting direction of the laser beams is deflected. Therefore, the reflected light at a point of incidence when the surface of the molten metal is approximately flat in the ridge or valley of the wave enters the photodetector 12. The data output from the photodetector 12 is changed in accordance with the level of the molten metal. The center value of the fluctuation is detected by the operating device, and the flow rate of the molten metal M is calculated from the value of the level. The flow rate of the molten metal can be presumed from the difference of the level from the height of the weir.
