Title: Anti-freezing device for golf course
Inventor: AKAZA MASATOMI
IPC: A01G25/06
Filed: 1989-12-12
Abstract: PURPOSE:To keep golf playable on a ground where freezing in the part near the surface is prevented by branching underground warm water pumped to a conveying pipe having high thermal conductivity wrapped with thermal insulating materials, and by laying same shallowly near the surface of the earth and extending to a putting green. CONSTITUTION:Warm water W pumped with a pump 8 through a suction pipe 9 that is extended deep into the ground is branched to a conveying pipe 11 made of material having high thermal conductivity. The conveying pipe is further laid, with thermal insulating materials 18 wrapped thereon, shallowly near the surface of the earth S until it reaches a putting green 4 through teeing grounds 3 of respective courses. The conveying pipe 11 placed between a pair of teeing marks 19 on the teeing ground 3 is formed of a plurality of straight- lined parts 13 and curved parts 14 that connect each of the adjoining straight- lined parts in U shape and is laid in zigzag line. The conveying pipe 11 under the teeing ground 3 is not covered with the thermal insulating materials 18, allowing the heat from the warm water W to be conducted to the ground through the conveying pipe 11 for effective warming under the ground.

Title: Forced air cooling structure
Inventor: MATSUMOTO SADAAKI
IPC: F25D1/00
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent the discharging air cooling efficiency from decreasing due to a reverse flow of air even when there is a stopped air discharging fan due to a failure, etc., by a method wherein on the air discharging port side where a plurality of air discharging fans are provided in parallel, a partitioning plate which is approx. in parallel with the air discharging direction, and has a sufficient size and a location wherein the streams by respective air discharging fans do not interfere with each other, is provided. SOLUTION: At an air discharging port 20 of a box body, a partitioning plate 40 which is approx. in parallel with the air drawing-discharging direction, and has a sufficient size and a location wherein air streams by respective air discharging fans 30a, 30b do not interfere with each other, is provided between the air discharging fans 30a and 30b.  Without the partitioning plate 40, when the air discharging fan 30a stops due to a failure, the part of the air discharging fan 30a becomes an opening, and air from the outside reverses in, and the adjacent air discharging fan 30b side under operation, draws the air and discharges to the outside and obstructs a cooling by a drawn/discharged air passed from an air suction port 10 to the air discharging port 20, but as a result of the provision of the partitioning plate 40, the reduction of the discharging air cooling efficiency due to a circulating stream by the reverse of the air, can be prevented from generating.

Abstract: PROBLEM TO BE SOLVED: To realize a smooth stop by braking with the regenerative braking of an induction motor in the case of getting into a neutral state during travel, and generating constant braking force during high speed, while generating braking force proportional to the speed when the speed becomes low. SOLUTION: When accelerator OFF is detected by an accelerator detecting part, or when a directional lever is set into the neutral state (NO in S1-S5 and neutral in S6), a determination is made on whether the speed degree V of a fork lift truck led out at that time is larger than the specified threshold Vt (S9), and the output voltage of the induction motor is computed so that braking force generated by regenerative braking is constant regardless of the speed of the fork lift when V is larger than Vt and that braking force generated by regenerative braking is proportional to the speed degree of the fork lift truck when V is smaller than Vt (S10, S11).

Title: Bias controller for copying machine
Inventor: KATO EIICHI
IPC: G03G21/00
Filed: 1987-12-24
Abstract: PURPOSE:To remove the belt-shaped base soil of a leading edge without side effect by setting a bias voltage impressed on the leading edge of an original higher than the base potential of a photsensitive body which raises its potential because it is shielded by a reflecting plate when a white original is copied. CONSTITUTION:A controller performs general control with the aid of a one-chip CPU 19 consisting of a ROM, a RAM and an I/O, and controls the inputs of reciprocating cluches 23 and 24 driving a scanner, an exposing lamp, an electrifying high voltage power source 21, etc. A bias power source 22 changes the pulse width of a trigger periodically by using the timer/even counter output terminal of the CPU19 as a trigger, and therefore said source can obtain any bias output voltage. Since it is a position 30mm ahead of the start position of the scanner that reflected light from an opposite reflecting plate 3 is shielded by a whitening reflecting plate 4 and ends up disappearing, the occurrence of the base soil of the leading edge can be prevented if a bias voltage covering part of the photosensitive body 8 corresponding to said disappearing position is set higher than a rising base voltage due to exposure shortage.
