Abstract: PURPOSE:To achieve higher operability with the shortening of transfer and connection time lengths by carrying a plurality of magnetic disk devices to be tested on a mobile type wagon to test the magnetic disk devices switching them sequentially with a test signal switching section. CONSTITUTION:A personal computer system 41 controls a power source control section 7 to feed a power of a power source 27 to one among four magnetic disk devices 50 while a test signal is sent to the devices 50 through a conversion board.

Title: Fuel injection device
Inventor: KUROYANAGI MASATOSHI
IPC: F02M59/32
Filed: 1983-02-24
Abstract: PURPOSE:To control so as to obtain the optimum injection rate in all operation areas including the starting time of an engine by changing fuel accumulating amount in accordance with the operating condition of the engine. CONSTITUTION:Upon low speed operation such as the idling of the engine, a fuel pressure in a pump chamber 10 is low, therefore, pressure of introduced fuel in operating fluid introducing chambers 57, 57 are low. Accordingly, a control vane 55 is energized so as to be pivoted into counterclockwise direction and is stopped at a position whereat the pressure of the introducing chamber 57 and the force of a spring 65 are balancing, therefore, the amount of injection may be decreased remarkably in case the axial distance between a control surface 37 and a control hole 39 is set so as to be large under this condition. In this case, injection time is elongated to supplement the decreased amount, then, noise upon idling may be reduced and efficient combustion may be obtained. Upon middle and high speed operations, the fuel pressure in the pump chamber 10 is increased, the vane 55 is pivoted into clockwise direction and an accumulate piston 36 is pivoted integrally, therefore, the amount of movement is restricted and the decreasing amount of the amount of injection may be reduced. Accordingly, the injection rate is increased suddenly and the efficient combustion may be obtained in all operation areas 1.

Abstract: PURPOSE:To eliminate the waste of time and nonuniformity at the boundary part by providing a bond-shaped rotor to a film compressing means and supplying a monomolecular material to a flow on a liq. surface caused by the rotation of the rotor through a monomolecular material supply means. CONSTITUTION:A belt 31 is firstly driven in the A direction to move the water surface in the A direction. A soln. of a monomolecular material is dripped on the water surface moved by the belt 31 by a molecular material supply means 40. Consequently, the dripped soln. is sent by the flow on the water surface into the liq. surface enclosed by a moving wall 60. The liq. surface is compressed by the monomolecular material, and a monomolecular film is formed on the enclosed liq. surface when the pressure of the liq. surface reaches a set value. At this time, the base body 51 of the film depositing means 50 is vertically moved by a controller orthogonally to the liq. surface, and the monomolecular film is deposited on the surface of the base body 51. When the monomolecular film is consumed in this way, the monomolecular material soln. is newly dripped on the moving belt 31 by the supply means 40.

Title: Automatic focusing adjuster for camera
Inventor: OWASHI MASAO
IPC: G03B3/00
Filed: 1988-02-10
Abstract: PURPOSE:To shorten a focus detecting time by appropriately setting a lens driving starting direction even when a focus detecting signal can not be obtained at the time of photographing by using a close photographic lens whose lens feed quantity is large. CONSTITUTION:A lens information identification circuit 211 outputs a close photographic lens attaching signal when an interchangeable lens 100 is for closely photographing or it is in a state where closely photographing can be possible. A posture detecting device 230 detects the posture of a camera and outputs a downward signal when the camera turns downward. And an arithmetic circuit 207 drives the photographic lens 101 to the closest side when the downward signal is outputted in a case where the close photographic lens attaching signal is outputted and a defocusing signal is not outputted, and it controls a motor 209 so as to drive the photographic lens to an infinity side when the downward signal is not outputted in the same case. Thus, the defocusing signal can be obtained soon by driving the photographic lens 101 to the closest side in case of performing close-up photographing when said lens, for example, is still in a state where long distance photographing is possible.

The circuit 10 converts this video signal from analog to digital and stores the result in a shift register 12. Then, the difference from the last value of the quantity of light is calculated by a subtracting circuit 13 to obtain the variation rate of the light quantity circuit 13 to obtain the variation rate of the light quantity value, i.e. differential value. This differential value is compared by a comparator 14 with a preset threshold value, and when a signal exceeding this threshold value is inputted, this is outputted as a defect part signal. This circuit operates continuously by a sample controller.

Title: Production of porous glass base material for optical fiber
Inventor: KAWAGUCHI SAKAE
IPC: G02B6/00
Filed: 1994-03-01
Abstract: PURPOSE:To improve the deposition rate of glass soot by using several target members and disposing these members on the center axis of the flame containing the glass soot. CONSTITUTION:Two or more heat-resistant target members such as synthesized quartz are disposed above oxyhydrogen burners which supply the glass source material such as SiCl4, O2 gas and H2 gas for combination and the target members are disposed on the center axis of the flame when the burners are ignited. Then the burners are ignited to deposit the glass soot essentially comprising SiO2 produced by flame hydrolysis on the first target member which is rotating. The glass soot which does not deposit on the first target member flows in the center axial direction of the flame and deposits on the second target member. The glass soot which does not deposit even on the second member further flows in the center axial direction of the flame to deposit on the third target member. Thus, the deposition rate of the glass soot is increased compared with the case using one target member. Thus, the porous glass base material for optical fiber can be efficiently obtd.

Title: Voltage controller
Inventor: OSAKI SHINICHI
IPC: G05F1/32
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To perform control so as to obtain maximum power saving in a short time by determining a tap to be selected according to the voltage value and continuance time of a straightforward state and varying a monitor time for the voltages of respective taps. SOLUTION: When an electromagnetic contactor (MC) 2 as a contact (b) is broken and MC1 as a contact (a) and one of semiconductor switches (SSR) 1 to Rn are broken to apply an input voltage Vi to one of taps T1 to Tn, the secondary voltage V2 of a transformer 1 is varied to control an output voltage Vo. As the value of (n) of a tap Tn is larger and larger, the secondary voltage of the transformer 1 is larger and larger. Namely, the output voltage Vo becomes smaller. When the (a)-contact MC1 is broken and the (b)-contact MC2 is made, both the ends of a primary winding 1a are connected and the straightforward state wherein the output voltage Vo is not passed through the transformer 1 is entered.  The voltage controller determines a tap to be selected according to the voltage value and continuance time of the straightforward state and varies the monitor time for the voltages of the respective taps.
