Title: Battery charger
Inventor: NAKANO SUKEAKI
IPC: H02J7/10
Filed: 1988-05-31
Abstract: PURPOSE:To prevent overcharge or undercharge by employing a temperature detection element having such characteristic as the detection output thereof is linear proportional to temperature variation and subtracting an initial value, i.e., the battery temperature at the start of charge operation, from a temperature output detected during charge operation. CONSTITUTION:Battery temperature detected through a temperature detecting element 3 at the start of charge operation is employed as an initial value, which is then subtracted from the output of the temperature detecting element 3 in the way of charge operation through a microcomputer 6, and a judgement is made on whether the initial value exceeds a set value. Since the temperature detecting element 3 produces an output linear proportional to the battery temperature, the initial value matches to the battery temperature rise from the start of charge operation regardless of the battery temperature at the start of charge operation. Consequently, the battery can be charged properly without causing overcharge nor undercharge and regardless of the ambient temperature by setting the set value corresponding to a proper charge amount.

IPC: A61B6/02
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To set an accurate tomographic mode which corresponds to a photographing state. SOLUTION: This apparatus is provided with a constitution which can change a laminal angle in such a way that, when a photographing mode having a wide photographing range is desired even when the resolution in the depth direction of the section MA of an object, to be photographed, including the point of intersection Ma of a radiation irradiation axis Xa with a shaft ra is low, a smaller laminal angle α1 is set and that, when a photographing mode used to increase the resolution in the depth direction is desired even when the photographing range is narrow, a larger laminal angle α2 is set. When the laminal angle can be changed, the right balance between the resolution in the depth direction of the object and the photographing range can be adjusted.  As a result, the degree of freedom of the photographing mode becomes large, and a tomographic operation which is matched to the photographing state can be performed.

Title: Reaction heat recovery process
Inventor: OOSAKI KOUZOU
IPC: C01C1/04
Filed: 1980-10-01
Abstract: PURPOSE: To provide a positive natural circulation flow and an efficient recovery of transformed reaction heat by a method wherein as a cooling liquid in a contact heat producing transformed reaction unit such a liquid as having a higher boiling point than that of water is used, and its liquid vapor is guided into a pressurized heat exchanger to produce a pressurized vapor.  
     CONSTITUTION: Raw material gas is passed from an inlet port 5 through a central space 6, catalyst layers 2, 3 in a horizontal direction to produce a transformed reaction heat and then discharged out through the outlet port 18. This transformed reaction heat is absorbed by oily cooling liquid having a higher boiling point than the ascending water in the cooling pipe 4 and then the liquid is boiled. The vapor of the oily cooling liquid or a gas-liquid mixture is entered into the heat exchanger 34 at the outlet port 18, and heat exchanged with water in the heat exchanger pipe so as to evaporate the same. The vapor is condensed and returned back to the reaction unit 1 under an operation of the pump 32. The steam vapor is collected in the steam drum 38. In this way, it is possible to prevent a deterioraton of natural circulation flow and to get a pressurized water vapor efficiently.

Filed: 1983-07-27
Abstract: PURPOSE:To obtain an efficient file access system for a replaceable type file device by confirming a file in file access request on the basis of stored information only when a medium is replaced. CONSTITUTION:When an operator replaces a flexible disk medium FD, an FD device 3 generates an attention interruption to a CPU1. A basic control program is stored on the medium FD and the generation of an interruption factor is stored. The basic control program reads a file directory out of the medium FD set in the FD device 3 unconditionally when the 1st file access request is generated by a user program. When no corresponding file is present, the basis control program displays a warning message to the operator or reports an error to the user program to prevent wrong input data from being processed as it is.

Abstract: PURPOSE:To realize a quiet sound in the course of standby by setting the speed of revolution of a polygon motor to the speed of revolution by which a noise generated by a rotation of the polygon motor is in the outside of an audio frequency band or in the vicinity of the outside of its band, in the course of standby. CONSTITUTION:A polygon motor turn-on/turn-off signal Trig is sent to a polygon control unit 11 from a process control unit 2, a power source of the unit 11 is turned on, and a polygon motor 10 is rotated. The rotation in the course of standby of the motor 10 is rotated by the speed of revolution of a noise being lower and quieter than the speed of revolution in the course of being ready or the speed of revolution in the course of copying in the outside of an audio frequency band. In this case, a READY signal 'H' is sent to the unit 2 from the unit 11. Thereafter, when a copy button is pushed, an SW signal becomes 'L', the motor 10 is accelerated up to the speed of revolution of the copy, and when it reaches the speed of revolution of the copy, the READY signal 'H' is sent to the unit 2 from the unit 11, and a copy sequence is started.

Title: Work aligning device
Inventor: KAJITANI YOSHIMI
IPC: B65G47/24
Filed: 1982-08-04
Abstract: PURPOSE:To simplify the constitution of a work aligning device having portions different in diameter in plural directions such as globe retainer (CVJ cage) for a uniform coupling and to facilitate alignment by providing a pair of discs rotating in the opposite direction with the gap between each periphery thereof and feeding a work through the gap from an upper passage wider than the gap to a lower passage narrower than the gap. CONSTITUTION:A CVJ cage 11 in guide rails 12, 13 is rotated counter-clockwise in a passage 16 by discs 1, 10 rotating in the opposite direction, and fed through the gap between the discs 1, 10 into a lower passage 17. Since the size of rails 14, 15 is a little larger than the width of an elongated opening of the CVJ cage 11, the cage is guided and moved without rolling by the rails 14, 15. In this arrangement, the rotating speed of the disc 10 is made higher than that of the disc 1, so as to smoothly drop the work into the passage 17. Thus, the work can be easily aligned in a simple constitution.

Filed: 1985-06-24
Abstract: PURPOSE:To transmit original data on an image of full size to all facsimile equipments without any data absence by providing a division processing function in a transmission side. CONSTITUTION:Image data on a transmit original 1 is stored in an original data storage circuit 3. A procedure analyzing circuit 14 analyzes an opposite- party procedure signal 20 sent from a circuit for transmission and sends information on the recording paper width of a reception-side facsimile equipment to a control part 16. The control part 16 compares sent original width information 21 from the original data storage circuit 3 with the recording paper width information from the reception side to determine whether or not data should be sent while being divided. When the recording paper of the receiving facsimile equipment is smaller than the transmission original width, image data from the original data storage circuit 3 is sent by a switch 5 to a data division processing circuit 8 and divided, and the divided data are sent to an original data editing circuit 10. When larger, the data need not be divided, so the data is made to by-pass the data division processing circuit 8 through the switch 5 and sent directly to the original data editing circuit 10.
