Title: Document shredder
Inventor: ITO TETSUYA
IPC: B02C18/24
Filed: 1988-12-02
Abstract: PURPOSE:To obtain the document shredder which widens the conditions for use and is improved in shredding efficiency by providing switching means for switching the windings for rotating a shredding motor according to shredding conditions. CONSTITUTION:The intermediate taps of the windings 2 of the shredding motor 1 are led out as switching terminals 4A, 4B, 4C in order to switch the shredding capacity. A power source 5 is supplied to the windings 2 via a power supply switch 3 and the winding switching means 4. The number of the paper which can be simultaneously shred by the shredder and the time when the shredding can be continuously executed are determined by the output torque of the shredding motor 1 and the temp. rise of the shredding motor 1, respectively. The output torque and the temp. rise are determined by the current (i) flowing in the shredding motor 1. Any of the switching terminals 4A to 4C is selected and switched according to the conditions of use. For example, all the operator has to do is to select the switching terminal meeting the conditions of use displayed in the table. Namely, the switching terminal 4C to increase the max. number of the sheets to be shred is merely selected if the number of the paper to be shred is small. The selection of the switching terminal 4A to execute continuous use suffices if a large amt. of the paper to be shred exists.

Title: Microcomputer system
Inventor: AASAA KAARITSUKU
IPC: G06F12/0893
Filed: 1990-11-13
Abstract: PURPOSE: To prevent lock-up by disabling the control of system bus from a peripheral device through a control means when a processor starts a lock instruction sequence. CONSTITUTION: The peripheral device controls a local bus 62 and when a microprocessor 48 starts the lock instruction sequence, a control means 40 defines the preparation completion input line of the microprocessor as false until the peripheral device stops controlling the local bus 62. While the preparation completion input line is defined as false, since the microprocessor 48 handles a system bus 56 as an input bus containing valid data, the system bus 56 is not driven by data. Therefore, the peripheral device can access a cache memory 42 through a transceiver 52 and the system bus 56.

Abstract: PROBLEM TO BE SOLVED: To judge the end of a battery life properly by observing the charging time of respective batteries each time, and determining the end of the battery life when the number of occurrence, in which the charging time is smaller than a predetermined value, exceeds a predetermined number of times. SOLUTION: When the reduction of a remaining battery amount is detected, the battery is transferred to a charging device so as to start charging. The charging amount of the battery during charging is detected, and when the battery is fully charged, a charging completion time is recorded. A required time for charging is obtained from a charging start time and the completion time, this time is compared with a reference time for judging the end of the battery life, and when this time is smaller than the reference time, the life judgement number of times is renewed. This number of times is compared with a reference value, and when this number is larger than the reference value, the use start date of the battery is read so as to judged whether the elapsed time is larger than a predetermined lifetime or not.  When the elapsed time passes the lifetime, the operating time of the battery is read, and the operating time is smaller than the predetermined time expressing the lifetime, the end of the battery life is determined.

Filed: 1990-11-15
Abstract: PURPOSE:To protect a compressor from damage induced by an improper amount of refrigerant by additionally charging the refrigerant whose amount is proportional to the following volumes based on the time which has elapsed until the pressure in the refrigerant circuit of the indoor equipment reaches a specific vacuum pressure, the specified vacuum pressure and the volume of air displaced per unit time by a vacuum pump, and the volume in the refrigerant circuit in the indoor equipment. CONSTITUTION:During unit installation, connection pipelines 6 and 7, an indoor heat exchanger 3, a vacuum pump 8 and a vacuum pressure gauge 9 are made to communicate with each other. Thereafter, the vacuum pump 8 is driven, and a timer device 10 measures time t1 until the pressure indicated by the vacuum pressure gauge 9 reaches a specific pressure P1. When the volume of air displaced per unit time by the vacuum pump 8 is VP, the sum V of the volume Vc of the connection pipelines 6 and 7 and the volume VI of the indoor heat exchanger can be determined form the equation V=-(VP tI)/(Ln P1). Therefore, it is determined by Vc=V-VI. Therefore, it is possible to obtain a proper amount of charge if additional refrigerant charge in proportion to the volume Vc of the connection pipelines 6 and 7 is carried out.
