Title: X-ray device
Inventor: SHIBATA KOUICHI
IPC: H05G1/32
Filed: 1979-05-31
Abstract: PURPOSE:To achieve the automation of warm-up by providing a warm-up circuit capable of enabling voltage during an initial period to rise continuously and making a control signal, the rising rate of which is decreasing during the initial and last period of warming up. CONSTITUTION:By switching a warm-up switch 21 to A position, charging a capacitor 30 and adjusting a resistor 14, a tube is set up at the maximum voltage. By switching the switch 21 to B position, an output corresponding to the minimum tube voltage is output from a comparator 12 and decreases to a voltage of the capacitor 30 by discharging. Referring to discharging curves (a) and (b), a transistor 31 gets rid of a saturation state and an output of the comparator commenses to rise gradually at time T1. At T2, a transistor 31 becomes to be in off-state and yields the output corresponding to the maximum tube voltage. After keeping this voltage for a while, the output of the comparator inverts and the warm-up is achieved.

Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a storage device array for preventing erroneous connection at the time of attaching/detaching a storage device. SOLUTION: CPU 101 judges whether a hard disk device 13 is exchanged or not. When it is exchanged, a port number to which the exchanged hard disk device 13 is connected is collated with a disk number transmitted from the hard disk device 13. When they are matched, whether the request of a data processing from a host device 2 exists or not is judged. When the request exists, the processing is executed. When abnormality occurs in the hard disk device 13, CPU 10 releases the locking of the hard disk device 13 where abnormality occurs and the disk number of the device is displayed on LED 15.

Filed: 1988-03-25
Abstract: PURPOSE:To easily and satisfactorily reduce the humidity of an atmosphere in which iron powder is stored and to prevent the rusting of the iron powder during storage by packing the iron powder after heating to a specified temp. above the temp. of the open air and cooling in a dehumidified atmosphere. CONSTITUTION:When iron powder as principal starting material for sintered parts is stored over a long period, the powder is first heated to a temp. above the temp. of the open air by 10-100 deg.C to remove the humid atmosphere in the powder. The powder is then cooled in a dehumidified atmosphere and packed. The dehumidified atmosphere flows in the powder and the dew point of the atmosphere in the powder drops. Dew condensation does not take place in the packed iron powder by a drop in temp. during storage and the rusting of the powder can be prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain an SDRAM which can access a memory fast by issuing a precharge command and an active command with one clock at the same time and processing them in a time 1/2 as long as before. SOLUTION: A preact address control circuit 34 receives a precharge command detected by a command decoder circuit 28 and generates a control signal 32a for latching an address to a preact address latch circuit 33. This control signal 32a is a latch signal for a memory cell asynchronous characteristic time and with this latch signal, a time of, for example, latching is carried out for two clock cycles. The timing of passing the held address to a row address buffer circuit 24 is given with two bits extended by a mode register 29. Consequently, row addresses needed for an active command can be inputted at the same time when the precharge command is issued and another command can be issued with the following clock.
