Filed: 1995-05-15
Abstract: PURPOSE: To provide a float valve capable of being normally functioning even when an inlet and an outlet are reversely piped, by providing a first check valve body allowing the inflow of fluid from a first opening to a valve chamber and inhibiting outflow from the valve chamber to the first opening, and a second check valve body allowing the inflow of the fluid from the second opening to the valve chamber and inhibiting the outflow from the valve chamber to a second closing/opening port. CONSTITUTION: In a piping where first and second openings 2 and 3 are adopted as an inlet and an outlet respectively, a first inflow port 10 is opened by a first check valve body 12, and a second inflow port 14 is opened by a second check valve body 16. A float 17 is floated or lowered by drain flowing in from a first inflow port 10 to open/close a second valve port 15. In contrast with thus, in a piping where the openings 3 and 2 are adopted as the inlet and the outlet respectively with a valve casing 1 turned upside down, the inflow ports 14 and 10 are opened by the check valve bodies 16 and 12 respectively. The float 17 is floated or lowered to open/close the valve port 11 by drain flowed in from the inflow port 14.

Inventor: KAARU HAINTSU KERAA
IPC: D05B33/00
Filed: 1989-06-05
Abstract: PURPOSE: To exactly align even the workpiece of a large surface area with a stopper member at a low cost by providing the device with a hook-shaped alignment member abutted to a turned-out ridge so as to move laterally to the lengthwise direction of the stopper member between a reference position away from the stopper member and an alignment position closer to the stopper member. CONSTITUTION: In order to insert a workpiece W to a sewing position, alignment members 12 of four alignment devices 7 are located at reference positions. When inserting the workpiece W, a folded section L of the workpiece W is passed under the carried-up alignment member 12, is pushed to a ridge K of the workpiece and comes into contact with a stopper ruler 6. Afterwards, an air cylinder 10 is turned backward and a piston rod 11 is returned. Thus, the ridge K of the workpiece previously brought into contact with the stopper ruler 6 is held in contact with the stopper ruler 6 and finally exactly aligned along with the stopper ruler. After the workpiece W is exactly aligned, the folded section L is succeeded by a workpiece clamp device added to respective sewing machines 3, 4 and 5.

Abstract: PURPOSE:To write data so as to be sufficiently read out from a disk on which data is recorded with ordinary low track density by means of a floppy disk device with high track density by controlling the device so that a servo signal is written prior to recording of data. CONSTITUTION:Whether a servo signal is recorded on a data area of an objective sector on a disk 13 or not is detected by a servo signal detecting circuit 8, and when the servo signal is not recorded, a servo signal is written in the data area of the objective sector by a servo signal storage device 3 prior to the writing of the data. Since the floppy disk device is controlled so that the servo signal is written in the data area prior to the writing of data, data can be written on the disk recording data with the ordinary low track density by the floppy disk device with high track density so that reading can be surely attained.

Title: Mis input protective circuit
Inventor: YASUNARI KENJIROU
IPC: H03K19/0944
Filed: 1978-11-20
Abstract: PURPOSE:To prevent the destruction of the gate information for the input MISFET by lowering the absolute value of the threshold voltage for clamping MISFET to prevent the transmission MISFET from being turned on. CONSTITUTION:The threshold level of clamping MISFETQ4 is set lower in terms of the absolute value than the threshold voltage of MISFETQ1-Q3 which constitute the normal logic circuit. And in case MISFETQ4 is the n-channel type, the n-type impurity is led into the channel region surface selectively through the gate insulator film. In this case, the clamping is given with the fixed voltage to the positive high voltage via the surface breakdown of FETQ4 and others in order to prevent the destruction. And in the case of the negative input voltage, the threshold voltage of FETQ4 is low. Thus transmission MISFETQ1 is not turned on, and as a result the destruction can be prevented for the gate information of input MISFETQ3.

Abstract: PURPOSE:To prevent deterioration with lapse of time by subjecting a transparent substrate in the stage in which a lower protective film is provided thereon to sputter etching by using a gaseous medium having a low etching rate to a lower protective film forming material and a high etching rate to a transparent substrate material. CONSTITUTION:After the lower protective film 2 is provided on the transparent substrate 1, the substrate is subjected to the sputter etching by using the gaseous medium having the low etching rate to the lower protective film forming material and the high etching rate to the transparent substrate forming material; thereafter, a recording film and upper protective film are successively laminated and formed on the protective film 2. The position of the recording in contact with a micropinhole contained in the lower protective film is thereby developed as a defect and, therefore, the recording of information is executable by skipping this position. The erasing of the optical recording medium during long-period preservation is thereby eliminated and the reliability is improved.
