Title: Rotation control system for cooling fan
Inventor: HIRATSUKA YOSHIAKI
IPC: H02P7/00
Filed: 1988-07-13
Abstract: PURPOSE:To fix a wind quantity at the time of a low temperature and to improve the quality of a system by rotating a fan for cooling at a high speed at the time of turning on the power source, and obtaining and controlling the number of rotations at the time of the low temperature based on the number of the rotations at the time of the high speed. CONSTITUTION:When power source 400 is turned on, a microprocessor 210 rotates a fan 100 for cooling at a high speed, reads the number of the rotations and judges the type of the fan. Thereafter, when a temperature instructing signal from a temperature sensor 300 shows the low temperature, the number of the rotations of the fan 100 is controlled so that the wind flow in the device can be fixed based on the type of the fan. Thus, even when the cooling fan used is different, the system down, etc., due to heating are prevented and the quality of a system is improved.

Title: Pachinko machine
Inventor: SATO SHOJI
IPC: A63F7/02
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce electricity consumption by shortening the energizing period of an electromagnetic solenoid involved in usage of an intermittent prize device that is equipped with a rotating member. SOLUTION: A precedent game ball B1, that has fallen inwards to a receiving part 3, gets into a guide hole 42 when an electric solenoid 45 of an intermittent prize device is off and a displacement member 40 is positioned in forward. When the electromagnetic solenoid 46 is on, the position changing member 40 starts moving backwards and the precedent game ball B1, which is being held in a guide hole 42, moves together with the displacement member 40 to get the upper half of the game ball B1 into a retreat room 68. When the displacement member 40 further retreats and the guide hole 42 comes to a plate approximately just above a detecting hole 64 of a approaching sensor 62, the precedent game ball B1 falls into a guide duct 66 from the guide hole 42 through the detecting hole 64 and the ball is discharged to the back of a game table 12.  To make the electric solenoid switched on with a proper timing and by this procedure is good enough to make the electricity consumption small. For the displacement member 40 shifts vertically versus the game table 12, the installation of the machine can get away with a small area.

Title: Reset-oriented level shift circuit insusceptible to noise
Inventor: DEIBITSUDO SHII TAMU
IPC: H03K19/003
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To eliminate malfunction due to an abrupt noise pulse by providing a set and a reset level circuit for threshold levels for their operations and setting the threshold level of the set level circuit lower than that of the reset level circuit. SOLUTION: Pulses from a pulse generator 80 are supplied to MOS FETs 81 and 82 for normal operations.

Title: Static elimination tool with luminous function
Inventor: DEGUCHI KATSUO
IPC: H05F3/04
Filed: 1994-07-04
Abstract: PURPOSE:To eliminate static electricity without any uneasiness during use by preventing numbness and an electrical shock due to the momentary discharge of the static electricity, and turning on a light emitting diode, upon the discharge thereof, for visual confirmation. CONSTITUTION:When a static electricity input electrode 2 (nickel plated stainless steel rod) is kept in contact with a positively charged body, the positive voltage level of a battery 10 is used as a reference voltage point for a first two-input negative logical sum digital IC 8. As a result, input voltage indicated with the first input terminal 8a of the IC 8 is at a positive level corresponding to a full positive side clamp level. Also, discharge electric current flows from the second resistor 5 to the third resistor 6 and, therefore, the voltage of the input terminal 8b of the IC 81 drops to an output level lower than the battery voltage at the reference voltage point. On the contrary, when the electrode 2 is in contact with a negatively charged body, the voltage of the terminal 8b is at a positive level corresponding to the full positive side damp level higher than the battery voltage at the reference voltage point, thereby generating negative level output.

Title: Boot for snow board including internal shell and hard back part which is connected with hinge
Inventor: JIYOERU BURUDOO
IPC: A63C10/00
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a flexible type boot capable of securing the transmission of stress essential to the improved management and control of a board in various enforced events. SOLUTION: A hard back part 6 is directly hinge connected to the rear part 42 of a shell with an axis O for forming an inlination angle θ to the center longitudinal direction surface P of this boot as a center, covers a part of the shell, is extended at the lower part of a hinge connection axis and forms strong rear part support required at the time of performing back side turn. The angle θis required to be within the range of 20 deg.-45 deg.. When it is less than 20 deg., it is not suitable for a purpose because front part bending components are sacrificed and side part bending components are accelerated. Further, since a hinge connection member is present near an Achilles' tendon, there is the possibility of causing a pain by the pressure of a back part present on the lower side of a hinge connection part by the rear part support.  When it exceeds 45 deg., while the front part bending components are accelerated inversely, side part bending is made difficult or impossible further by rigidity especially at the part of hinge connection.
