Title: Magnetic recording and reproducing device
Inventor: KIMURA TAKASHI
IPC: H04N5/782
Filed: 1984-02-15
Abstract: PURPOSE:To eliminate the disturbance to the control and to achieve stable tracking control by providing a gate device which inhibits transmission of pilot signals in the vicinity of a head switching point at the time of reproduction. CONSTITUTION:Signals reproduced from a tape 1 by video heads 5 and 6 are inputted in a tracking error signal forming circuit 19 through a preamplifier 13, LPF15, and gate circuit 18. A tracking error signal TR outputted from the circuit 19 is inputted in a capstan motor driving circuit 8 through an LPF30 and by controlling the rotation of the capstan motor 3 the running phase of the tape 1 is controlled. On the other hand, a head switching signal SW is sent to a gate signal forming circuit 17 and a gate signal G generated from the circuit 17 is inputted in the gate circuit 18. In a prescribed period when transmission of a pilot signal PL from the LPF15 is inhibited, a tracking signal in which the previous value is held is outputted and stable tracking control is performed.

Title: Apparatus of metallic halide
Inventor: ISHIBASHI KIYOSHI
IPC: F17C11/00
Filed: 1991-01-28
Abstract: PURPOSE:To prevent damage of a box due to expansion of a metallic hydride by providing an inner vessel for sealing the metallic hydride, an outer peripheral wall connecting plural partition walls extending in the radial direction to outer ends of the partition walls and further installing outer lateral chambers between the outer peripheral wall and the inner peripheral wall of the outer shell. CONSTITUTION:Hydrogen is passed from a hydrogen feeder through a hollow passage (12a) of a filter 12, permeated through the filter 12 and admitted into inner lateral cambers 15. Thereby, a metallic hydride 13 is reacted to generate heat and simultaneously expand. The outer peripheral wall 17 of an aluminum hollow device 14 is expanded in the radial direction by the expansion and plastically deformed so as to collapse the outer lateral chambers 15. As a result, expanding force of the metallic hydride 13 will not directly act on the outer shell 11. In addition, since the outer peripheral walls 17 are brought into contact with the inner peripheral surface of the outer shell, the generated heat can rapidly be transmitted through contact parts and the radially extended partition walls 18 to the outer shell 11. Gases in the outer lateral chambers 16 are made to flow back into a space between a lid of the hollow device and the outer shell 11 and the filter and the deformation of the outer peripheral wall 17 is not prevented by the outer lateral chambers 16.

Abstract: PURPOSE:To prevent danger due to continuous power application of a heater, by controlling the power application of the heater based on a detected output of a temperature sensing element and informing open wire through the periodical detection of open wire. CONSTITUTION:In applying a power switch 33, an output signal of an output generating circuit 12 is started from a period T1, then a transistor (TR)13 is set off and no switching relay 14 is excited, a thermister 5 is activated for the control of a heater 11 to turn on and off an AC switching circuit 10 based on the output of a temperature detection circuit 4, and the power application of the heater 11 is controlled. When a detection pulse is outputted for a time T2 from the circuit 12, the TR13 is set on, the relay 14 is excited, the themister 5 is connected to a positive input of a comparator 18 for the detection of open wire. In this case, when the thermister 5 is opened, an L level is given from the comparator 18 to turn off a TR19. Further, a TR20 is also set off. After a delay time with a resistor 28 and a capacitor 29, a TR21 is turned on, an LED 31 is illuminated to inform the open wire.

IPC: F02D9/02
Filed: 1990-02-05
Abstract: PURPOSE:To prevent generation of engine stall caused by complete block by setting the minimum opening of a second throttle valve by means of a traction controller larger than the full close opening, when the opening at the time of the full close of the second throttle valve exceeds an initially set value by a preset quantity. CONSTITUTION:In the intake system of an engine a second throttle valve B is provided in series to a first throttle valve A linked to acceleration operation and these openings are detected by a means C respectively. Under an operation condition where slipping rates of wheels are high, the second throttle valve B is throttle-controlled by a traction controller D.

Title: Image file transmitter
Inventor: WADA YOSHINORI
IPC: H04M11/00
Filed: 1995-01-23
Abstract: PURPOSE:To improve the utilizing efficiency of a transmission line and the transmitter by sending a transmission file of the same destination successively under a specific condition. CONSTITUTION:When an image file corresponding to an original to be sent is formed in an image memory 2c, a CPU 2e sets a file management table managing the image file to a RAM 2g. After the end of immediate transmission of the transmission file, the CPU 2e retrieves a simultaneous transmission file of the same destination via the RAM 2g to receive an image from the memory 2c and sends the image to the transmission line from a facsimile section 1 before the transmission line is open. The CPU 2e retrieves a time designation transmission file of the same destination via the RAM 2g and sends it to the transmission line after the transmission of the simultaneous transmission file is finished and before the transmission line is open. Thus, the image file being stored and not sent yet is prevented from being left and the utilizing efficiency of a communication channel is improved.
