Title: Moisture content separating heater
Inventor: KAWADA KUNIHIKO
IPC: F22B37/26
Filed: 1988-04-01
Abstract: PURPOSE:To prevent the incurring of a pressure loss due to turbulence of steam flow in a heater and to prevent the occurrence of erosion due to a moisture content, by a method wherein steam flow baffle plates are mounted to positions before and after a corrugated plate and the outlet port of a heater. CONSTITUTION:Steam 10 to be heated containing a moisture content is guided to a heater through a guide vane 6, and steam 13 containing a moisture content guided to a heater is guided to corrugated plates 4 by means of steam flow baffle plates 20 without colliding with a support plate 16. Steam 14 freed from a moisture content by the passage through the corrugated plate 4 is joined with each flow from both sides, but thanks to a baffle plate 21 located at a central part, the joined steam flow is introduced to a heating pipe 2a without collision with each other to heat it. The heated steam is also smoothly guided to a steam outlet 7 by means of baffle plates 22. Those baffle plates prevent lowering of efficiency due to a pressure loss, and enable the reduction in generating vibrations exerted on a heating pipe.

Title: Large capacity disk device
Inventor: ODA YOSHIAKI
IPC: G11B17/26
Filed: 1988-04-01
Abstract: PURPOSE:To increase the number of sheets of cartridges to be stored, and to speed up access by providing a carrier with the rotating device of the cartridge approximately at the central part of a radial shape so as to be capable of moving vertically. CONSTITUTION:When the cartridge 6 containing an optical disk is inserted to a charting and discharging port 5, a charging and discharging mechanism part 3 moves to the position of the charging and discharging port 5, and receives the cartridge 6. Thus, the mechanism part 3 moves to the position of a rack 11a. Next, when a carrying device 13 rotates and in addition, lifts a carrier 4 so as to correspond to the mechanism part 3, the carrier 4 takes out and carries the cartridge 6 to the position of an optical disk device 2 or the rack 11. In this case, at the time to carry it to the rack 11b-11f other than the rack 11a, the carrier 4 is revolved in a direction to minimize the angle of rotation by the operation of the device 13 so that the carrier 4 corresponds to the desired rack 11b-11f in minimum time. Hereafter, a similar operation is repeated between the racks 11a-11f and the device 2.

Title: Pulse generating circuit
Inventor: ONO JIYUNZOU
IPC: H03K17/22
Filed: 1980-06-10
Abstract: PURPOSE:To obtain a reset pulse regardless of a gentle rise of voltage during application of power supply, by actuating a switching element with a difference between the signal that answers to the controlling reference voltage source of an output voltage control transistor of a voltage stabilizing circuit and the signal that answers to the output of the said stabilizing circuit. CONSTITUTION:When a power supply switch SW1 is turned on, capacitors C4 and C2 start charging by a power source E. Then the collector voltage and the base voltage of a transistor TRQ1 rise, and later the emitter voltage reaches the maximum level to be applied to the emitter of a TRQ2. At the same time, the voltage obtained at the point of connection between a Zener diode D4 and a diode D3 is applied to the base of the TRQ2. When the emitter voltage of the TRQ2 rises up to a level that is sufficiently higher than the base voltage, the TRQ2 switches to on from off. Thus, a differential pulse can be obtained at an output terminal A of a differentiating circuit.

Title: Interface circuit
Inventor: ANZAI FUMIHIKO
IPC: G06F12/00
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To enable reading operation from an external CPU even when an inner memory is being reset. SOLUTION: While an inner memory is reset, an access from an external CPU is normally suppressed, but a ready signal is made effective (low state) regarding the external CPU and reading of the data from the internal memory is enabled by taking a NAND logic with an ACCSOK signal as effective (in high state) at a read demand signal RDRQ from the external CPU and a NAND gate 17. Thus, since the ready signal is outputted even when the inner memory is reset, the external CPU can normally complete read operation.
