Title: Disk transfer device
Inventor: NAKAMICHI NIRO
IPC: G11B17/04
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To eliminate the incompatible operation feeling of a user caused by a difference in disk diameter by inserting a disk into a device, determining a disk diameter before the disk is transferred and, based on the result of this detection, varying a timing for starting the transfer of the disk. SOLUTION: When a user inserts a disk, the position of a disk inserting end part is different because of a different in disk diameter. By utilizing that, a disk diameter is determined by a detection arm 41. Simultaneously, a distance between a belt mechanism 10 and a guide mechanism 20 is started to be increased. In the case of a 12 cm disk, the transfer belt mechanism is not driven before this distance becomes one for transferring the disk by holding. Thus, even if a driving belt is driven at the time of inserting the 12 cm disk, the disk is not transferred unless the disk is further inserted and, a conventional disadvantage of an operation feeling totally different from an 8 cm disk is eliminated.

Title: Pneumatic paper-feed check apparatus in printing press
IPC: B65H7/04
Filed: 1991-04-18
Abstract: PURPOSE: To obtain a pneumatic paper-feed check apparatus for a printing press simple in its structure and usable for all printing materials and paper sizes by installing in addition to a suction system anemometer comprising a flow sensor, analogue signal lead and an analysis circuit. CONSTITUTION: The decompression generated by a decompression generator 30 when paper lack is detected in a T-type tubular body 14 causes an airflow from A to B which cools hot wire 16 of a flow sensor 1, the cooling causes in turn resistance variations and signal variations are processed in an analysis circuit 2. Here, the bridge composed of the wire 16 and the resistance body is synchronized so as that extremely low diagonal voltage may be generated when there exists no airflow. Because of such a coordination circuit, actuation voltage of the bridge is proportional to the airflow volume in the sensor 1. Since this coordination circuit allows only very small temperature fluctuations of the wire 16, temperature-time constant is extremely reduced, total reaction time of anemometers 1, 7 and 2 becomes very short, and reliable functions are assured even at the maximum mechanical speed.

Title: Refrigeration cycle
Inventor: HONDA SHIN
IPC: F25B43/02
Filed: 1990-04-27
Abstract: PURPOSE:To permit the securing of lubrication of a compressor by a method wherein an oil adsorbing member, adsorbing oil liquefied in a condenser, is provided in the high-pressure liquid section of a refrigerating cycle so as to contact with liquid refrigerant, containing the oil, at all times. CONSTITUTION:Lubricating oil is discharged and enters a condenser 2 when refrigerant is discharged out of a compressor 1, then, enters a receiver after being dissolved into liquid refrigerant liquefied in the condenser 2. An oil adsorbing member 9 is dipped into the liquid refrigerant 8 at a low liquid level LQL in the receiver 3. Upon a load higher than middle cooling load M, liquid in the receiver 3 is separated into two phases of the refrigerant and the oil. In this case, the concentration of the oil in the refrigerant is reduced from phi0% to phi'0% and, therefore, the concentration of the oil in the refrigerant circulating through a cycle can be reduced by adsorbing the separated oil by the oil adsorbing member 9. Accordingly, the coefficient of performance(COP) of the cycle can be improved from point A under the concentration phi0 to another point B under the concentration phi'0. When the load is reduced to a load lower than the middle cooling load, the temperature of the liquid refrigerant is reduced whereby the oil in the oil adsorbing member 9 is dissolved and eluated into the refrigerant and, therefore, the COP of the refrigerating cycle becomes the point A.

Title: Device for controlling charge current to battery
Inventor: KOMATSU ITSUKI
IPC: H01M10/44
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To enable charging in a short time and the prolongation of a battery service life by gradually reducing the charge current to be charged into a battery arbitrarily and continuously, accompanied by the increase of the remaining capacity of the battery. SOLUTION: At the start of charge of a battery, this device applies a large charge current to a battery since the residual capacity of a battery detected with battery remaining capacity detection means 11 and 12 and the battery voltage are dropping. Then, this drops the charge current gradually, accompanying the rise of the battery voltage and the increase of the remaining capacity of the battery, by means of a charge current command means 16. Then, when the charge current reaches a preset value, this decreases it to a minute current once and starts the next charge by means of a data processing means 15. Then, when it reaches a designated point, the remaining capacity becomes roughly 100%, and this terminates the charge to the battery. As a result, the charge in a short time becomes possible without damaging the battery, and can prolong the service life of the battery.
