Title: Piezoelectric vibrator
Inventor: IWASHITA NOBUSHI
IPC: G01N29/24
Filed: 1986-01-31
Abstract: PURPOSE:To prevent the damage of acoustic characteristics and to facilitate the lead-out of lead wires by forming an electrode of the second layer through an electric insulating layer on an electrode of one face of a piezoelectric vibrator where electrodes are provided on both faces of a piezoelectric body. CONSTITUTION:A shield electrode 14 is formed on one electrode 11 through an insulating layer 13. Since acoustic impedances of electrodes 11 and 12, a piezoelectric body 10, the insulating layer 13, and the electrode 14 are easily equalized approximately by this constitution, a fundamental frequency can be handled as a lambda/2 resonance frequency calculated at an average acoustic velocity for the thickness of the whole and acoustic characteristics are not damaged. With respect to the insulating layer, a metallic oxide film consisting of alumina, silicon oxide, or the like whose acoustic impedance approximates that of materials of electrodes is formed by vapor deposition or printing. Lead wires are led out similarly to essential lead wires of electrodes 11 and 12 and conventional special considerations of the forming process of a matching layer and an acoustic lens are made unnecessary.

Title: Air-cooled heat pump system refrigertor
Inventor: KAWAMOTO YASUO
IPC: F25D21/00
Filed: 1983-02-10
Abstract: PURPOSE:To provide an air-cooled heat pump type refrigerator which performs a defrosting only at a neccessary time even if an open-air temperature falls, by a method wherein a defrosting control is conducted such that, in case each electric contact is closed and an integrating timer reaches a set time, a defrosting operation starts. CONSTITUTION:A contact 5 of an electromagnetic switch for compressor, a contact 6 of a relative humidity detector being set to a frosting limit, a contact 7 of an open-air temperature detector, a coil 8 of an integrating timer are connected in series to each other. The contact 5 is adapted to close during operation of a compressor, and the contacts 6 and 7 to close in case an open-air condition enters within a range of E.B.C.D in a fig. 1. If a total value of times at a time when the 3 contacts 5, 6 and 7 are closed becomes constant, a defrosting starts. This prevents a device from performing a defrosting operation if beyond a scope of a set value even if an open-air temperature falls, whereby a stable heating operation can be conducted even in case an open-air temperature is low, and a heating capacity is improved.

IPC: C07C321/18
Filed: 1984-02-06
Abstract: PURPOSE:To obtain a disulfide useful as dye, drugs, various kinds of high polymer additives, by reacting an arylthionitrite with a mercaptan. CONSTITUTION:A thionitrite shown by the formula R<1>-SNO (R<1> is aryl, alkyl- substituted aryl, or halogen-substituted aryl) is reacted with a mercaptan shown by the formula R<2>-SH (R<2> is alkyl, cycloalkyl, aryl, etc.) to give a disulfide shown by the formula R<1>-S-S-R<2>. For example, an arylthionitrite is optionally dissolved or suspended in a solvent, kept at -30-10 deg.C, and reacted with a theoretical amount of a mercaptan. The reaction mechanism is not clear, but the mercaptan as a nucleating agent is considered to be reacted with the thionitrite, to give the desired disulfide in extremely high yield easily irrespective of symmetrical or asymmetrical form.

Title: Method and device for detecting alternating current light voltage
Inventor: MUNAKATA TADASUKE
IPC: H01L31/04
Filed: 1985-02-06
Abstract: PURPOSE:To increase a light voltage signal and to improve the S/N ratio by irradiating one surface of a semiconductor with DC photon rays. CONSTITUTION:The reverse surface of the semiconductor sample 1 is irradiated with short-wavelength light and a light voltage generated on the reverse surface of the sample 1 is suppressed with photon rays. Therefore, the light voltage on the reverse surface of the sample 1 is superior between light voltages detected by transparent electrodes 3 and 3' and the detected voltages are increased substantially. In this case, the entire reverse surface of the sample 1 is irradiated with the 2nd photo rays 1 at the same time, but the entire reverse surface need not be irradiated at the same time. Because the generation area of the light voltage generated by the irradiation of the photon rays 4 is limited to near the passing area of the photon rays 4 and the light voltage generation area on the reverse surface of the sample 1 is also limited to near the path of the photon rays 4. Consequently, the irradiation of the photon rays 11 may be limited to the light voltage generation area. Therefore, the photon rays 11 are converged according to the sectional area of the photon rays 11 are moved in synchronism with the movement of the photon rays 4.

Abstract: PURPOSE: To obtain polypropyrene film having antiblocking property, sliding property and transparency by extruding and cooling a sheet board on molten polypropyrene added with a small quantity of amido plural copolymer and then elongating the said sheet through dual axises after melting, extrusion and cooling.  
     CONSTITUTION: A mixed resin obtained by adding 0.2W5.0wt% of amido plural copolymer at melting point of less than 150°C which contains more than 30mol% of monomer components such as C 10  selected from lactam, aliphatic diamine, aliphatic dicarboxylic acir or ω-amino carboxylic acid to polypropyrene, is resolved and extruded. After maintaining the surfacial temperature of the extruded sheet at 60W100°C for more than 2sec, it is solidified. Next, this sheet is diaxially elongated at temperature below the melting point of polypropyrene and above the melting point of amido plural copolymer. If the content of monomer components of the afore-mentioned polyamide is equivalent to not more than 30mol%, it is not fully compatible with polypropyrene and the mixed resin has difficulty in extrusion operation.

Title: Preventing work for fluidization of ground
Inventor: FUKUSHIMA SHINJI
IPC: E02D3/08
Filed: 1986-02-03
Abstract: PURPOSE:To obtain sufficient preventing effects on the fluidization of the ground without any vibration and impact during the construction period by inserting a reinforcing material formed by packing water-permeable coarse grains into a netted pipe into a pit excavated in a ground possible to be fluidized. CONSTITUTION:A reinforcing material 4 formed by packing water-permeable coarse grains 3, e.g., gravels, etc., into a plastic or steel netted pipe is inserted into a pit 5 excavated in a ground 1 possible to be fluidized, and sand, etc., is packed into the space between the pit 5 and the material 4. The deformation of the ground can thus be restricted by the friction between the pipe 2 and the surrounding ground, the generation of void water pressure in the ground can also be extremely suppressed. Also, void water in the ground can be allowed to drain through the surrounding ground and the coarse grains 3. Therefore, the fluidization of the ground can be effectively prevented by combined effects of the deformation restriction of the ground.
