Title: Radio communication equipment
Inventor: YAMAMOTO MASAHIRO
IPC: G08C17/02
Filed: 1993-12-27
Abstract: PURPOSE:To obtain the communication system with high reliability by using a clock signal for both a PLL and a microcomputer by a clock signal from one oscillator so as to reduce the cost. CONSTITUTION:When a frequency oscillated by an oscillation means 1 is not a frequency required for a control means 4 or a PLL means 3, the frequency is divided or multiplied by using a frequency divider function in the inside of the means 4 or 3. The means 4 sets a power supply for the means 3 and selects a clock signal for a microcomputer from a sub clock signal into a main clock signal for succeeding transmission processing before and after the PLL is locked. It is general that much time takes to obtain normal oscillation of the main clock signal. Since the clock signal for the means 3, 4 is used in common, the presence of the oscillation of the main clock signal is confirmed by the clock signal of the means 3. Since the clock time of the means 3 is confirmed, the timing when the sub clock signal is switched into the main clock signal is checked.

Title: Production of fiber reinforced cement plate
Inventor: MATSUKAWA ATSUSHI
IPC: B32B13/12
Filed: 1988-12-27
Abstract: PURPOSE:To impart sufficient flexural strength and deflecting properties even in asbestosless blending by applying synthetic resin emulsion coating mixed with glass fiber to the single surface of cement plate which incorporates fiber excepting asbestos as reinforcing fiber and has been cured and hardened and drying the signal face of cement plate. CONSTITUTION:Synthetic resin emulsion coating mixed with glass fiber is applied to the single surface of cement plate which incorporates fiber excepting asbestos as reinforcing fiber and has been cured and hardened and this single surface of cement plate is dried. As fiber excepting asbestos, for example, pulp fiber, glass fiber and synthetic fiber, etc., are utilized for reinforcing fiber. As its producing method, any one of a dry method, a sheet manufacturing method and extrusion-molding may be performed. The molded plate material is impaired in the physical characteristic properties such as flexural strength and deflecting properties in comparison with the plate material with asbestos fiber added thereto. When synthetic resin emulsion with glass fiber added thereto as reinforcing fiber is applied to the rear of the plate material and this is utilized as a reinforcing layer, glass fiber is integrated with cement plate via synthetic resin emulsion. Therefore the possibilities for alkali erosion are eliminated and sufficient reinforcing effect can be exhibited.

Abstract: PROBLEM TO BE SOLVED: To produce a phosphor which comprises luminescent inorg. particles having nanostructures, clean surfaces, and controllable particle sizes. SOLUTION: One g of a carbon nanotube material, together with a mixture of 1.1 g of yttrium chloride and 40 mg of europium chloride, is put into a glass tube, which is then filled with a chlorine gas and sealed. The contents in the glass tube are heated at 800 deg.C for 6 days. The interlayer bonding reaction proceeds as follow: 18C+Y(Eu)Cl3 →C18 Y(EU)Cl3 . The resultant interlayer compd. is taken out and is kept standing at 200 deg.C for 1 hr in flowing air contg. moisture. The separation reaction proceeds as follows: 2C18 Y(EU)Cl3 +3H2 O→[T(Eu)]2 O3 +36C↑. The oxidized Y-Eu particles are attached to the surface of each carbon nanotube. The size of each carbon nanotube (varying from 1 nm to 30 nm) determines the size of a luminescent oxide nanoparticle. The red PL luminescence by Eu<3+> of this sample caused by excitation with an ultraviolet ray of 253 nm is confirmed.

Title: Gas compressor
Inventor: TAKAHASHI TORU
IPC: F04C18/344
Filed: 1993-12-27
Abstract: PURPOSE:To prevent an ill effect such as the generation of noise and the increase of starting torque caused by the compression of a large quantity of lubricating oil at the time of resuming operation. CONSTITUTION:A gas compressor is provided with a pressure control valve 18 for releasing refrigerant gas in a high pressure chamber 5 to a low pressure chamber 4 so as to set the low pressure chamber 4 and the high pressure chamber 5 in the pressure equalized state at the time of stopping the compression of refrigerant gas compressed by a compressor body 3. Accordingly, when the compression of refrigerant gas by the compressor body 3 is stopped, the pressure difference between the low pressure chamber 4 and the high pressure chamber 5 is eliminated immediately after the stop so as to stop lubricating oil force-fed to the sliding part of the compressor body 3 through an oil feeding passage 17 and lubricating oil flowing into the low pressure chamber 4 from the sliding part. Lubricating oil accumulated in the low pressure chamber 4 is thereby reduced to the least possible quantity so as to reduce lubricating oil to be sucked from the low pressure chamber 4 and compressed at the time of resuming operation.
