Title: Recess structure for accommodating lifter of engine
Inventor: NIITSUMA KEIICHIRO
IPC: F01M9/10
Filed: 1997-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a recess structure for accommodating a lifter, which is preferable for a motorcycle. SOLUTION: As understood from a comparison example (a), oil is fed into and a lifer accommodating recess 171 through an oil through-hole 172 so as to filled therein. On the contrary, in an embodiment (b), oil fed into the lifter accommodating recess 171 through the oil through-hole 172, can be discharged through an oil relief groove 178, so that the oil is not collected by a large quantity in the recess 171. Thus, in an engine even having such a structure that the axis of a cylinder is substantially horizontal so that oil is likely to be collected in the lifter accommodating recess 171, the oil can be effectively relieved through the oil relief groove 178, thereby it is possible smoothly operate a valve mechanism.

Title: Power source device for driving magnetron
Inventor: YASUI KENJI
IPC: H01J23/34
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To reduce intensity of an unwanted radiated radio waves. SOLUTION: Unidirectional source power attained by rectifying the commercial power source 1 is converted into a high frequency AC power source by an inverter circuit 3, and high voltage high frequency AC power is generated in secondary winding output of a step-up transformer 4 to constitute the inverter circuit 3. This high voltage high frequency AC electric power is rectified by a full wave voltage doupler rectifying circuit 6 by a pair of diodes and a pair of capacitors 6a and 6b, and high tension DC voltage is supplied to a magnetron 7.  Since intensity of unnecessary radiation by an anode current Ia of the magnetron 7 increases in proportion to a peak value and a change, its both are reduced by full wave voltage doubler rectification, and intensity of unnecessary radiation is substantially reduced, and capacity of the capacitors 6a and 6b is set large, and is set not less than 0.01μF, and intensity of unnecessary radiation is effectively reduced.

Title: Water-retaining material composition and production of thermally crosslinked biodegradable hydrogel to be used in the composition
Inventor: SAKUTA NOBUYUKI
IPC: C08L67/02
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a biodegradable material disposable without forming an environmental contamination source and hydrolyzable with time or decomposable by soil bacteria. SOLUTION: The objective thermally crosslinked biodegradable hydrogel is produced by mixing 1.0 mol of a polyfunctional carboxylic acid (citric acid, etc.) with 1.0-2.0 mol of a polyether (polyethylene glycol having a weight-average molecular weight of 100-2,000) under reduced pressure (30 Torr) and heating the mixture under normal pressure to effect the crosslinking of the reaction mixture. An organotin compound such as butyltin oxide may be used as a catalyst. The produced hydrogel has small zebound resilience and can absorb and hold 2-10 times weight of water based on its own weight. It is completely soluble in water in about 2 weeks and hydrolyzed to polyfunctional carboxylic acid and polyether.  Furthermore, the hydrogel is disposable to the soil without forming an environmental contamination source because it is decomposed into water and carbon dioxide by the microorganisms in soil. The water-retainability, the gel strength and the biodegrading rate are adjustable by the addition of proper amounts of bentonite, silica,,wood flour, starch, etc. The gel is usable as daily commodity, disposable water-retaining agent for soil, vibration insulator, cushioning material, etc.

A defreezing tray 44 on which a good 45 to be defrozen is placed is provided. A ventilating flue 50 is formed in the rear space of the reflection plate 39 and communicated to a damper thermo 20 for regulating a cold air inflow amount mounted to the inlet of the defreezing chamber, and a number of ventilating holes are formed in the reflection plate 39. Simultaneously, during defreezing, energization of the far infrared ray heater 34 and the heater 42 is intermittently effected by a defreezing control device. With the lapse of a time, a continuous energization factor is reduced stagedly, and a blower 18 is continuously run. During non-defreezing, the defreezing chamber 15 is kept at a third temperature zone between a refrigerating temperature and a freezing temperature to insulate heat. This constitution enables execution of defreezing having little unevenness in defreezing.

Abstract: PROBLEM TO BE SOLVED: To enable a call through a base unit outside the belonging of a hand set or a direct call between hand sets belonging to different base units by additionally registering a common system ID (CS-ID) to the base unit and hand set desired, to be newly connected, and setting a radio line while using this CS-ID. SOLUTION: The CS-ID is registered on both the base unit side and the hand set side. In this case, the CS-ID and the 'PS-ID' of the hand set, desired to be newly connectable to this base unit, are additionally inputted to the base unit side. Further, the 'CS-ID' similarly registered to the base unit as well is registered additionally to the hand set side. Then, an LCCH superframe is transmitted, while inserting the 'CS(common)-ID' into a 2nd report channel BCCH(B) in one direction. Since the base unit and the hand set transmit/receive various signals into which the 'CS-ID' has been inserted, a call can be originated and terminated between a certain base unit and the hand set belonging to the other base unit.
