Title: Valve on-off device
Inventor: KAWASAKI MASAMI
IPC: A23L7/10
Filed: 1991-09-06
Abstract: PURPOSE:To secure both the on-off states of a valve so accurately by installing a reversible motor with an output shaft concentrically as a handle, and setting up a clutch mechanism in space between the handle and the output shaft. CONSTITUTION:An on-off valve 4 is made so as to be opened or closed by rotating a handle 3 attached tight to a valve stem 2. Especially there is provided a reversible motor 6 having an output shaft 5 concentrically with the handle 3, transmitting power of the output shaft 5 to the handle 3 in an intervalve between this handle 3 and the output shaft 5, and thereis provided a clutch mechanism 7 which releases the transmission at a time when resistance has grown larger. An on-off motion speed of the on-off valve 4 depends upon the extent of rotational speed of the reversible motor 6, namely, it is set to be later enough than the case to be driven by an electromagnet. With this constitution, the on-off valve 4 is slowly opened or closed in taking a lot of time and, what is more, it becomes possible to be stopped in the point midway in opening or closing. In this connection, even if the on-off valve 4 is made so as to be opened or closed by the reversible motor 6, both the on-off states of the valve are accurately securable.

Title: Image reader using charge coupled device line sensor
Inventor: WATANABE YOSHIHIRO
IPC: G06T1/00
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in image data resulting from a light that is not made incident onto a CCD line sensor for a long period. SOLUTION: An auxiliary light source 18 is lighted before a print medium 11 moves a carrying path 12 and comes at a position of a window 16 to provide a light to a CCD line sensor 14. When the print medium 11 reaches the window 16, the auxiliary light source 18 is turned out and a lighting light source 17 is lighted. The CCD line sensor 14 receives a light from the light source 17 that is diffused because the print medium 11 is placed at the window 16 of the carrying path 12 and converts the light into image data. Thus, a period when no light is given to the CCD line sensor 14 is reduced and the print medium is read while charges remain in the CCD line sensor 14.

Title: Floating type magnetic head stable in reproducing output
Inventor: NOGUCHI KAZUMI
IPC: G11B5/60
Filed: 1985-10-14
Abstract: PURPOSE:To realize a magnetic head whose reproducing output is scarcely varied against a variation of a floating quantity, by crossing diagonally alloy thin films at 30-120 deg., when joining the alloy thin films on a pair of V-shaped substrates through a gap part. CONSTITUTION:Alloy thin films 3, 4 having a high saturation magnetic flux density are formed on V-shaped substrates 1, 2, and the substrates 1, 2 are joined through a magnetic gap 6. In that case, the alloy thin films, 3, 4 are crossed diagonally at an angle of 30-120 deg.. When such a head is used, its reproducing output becomes stable extremely against a variation of a floating quantity. Its reason is not clear, but it is considered that it is caused by a fact that a distribution of a magnetic flux which leaks from the magnetic gap is different from that of a magnetic head of a conventional constitution. Therefore, a head whose reproducing output is stable against a variation of the floating quantity being indispensable for a high density recording can be obtained.

Title: Alignment
Inventor: OTA KAZUYA
IPC: H01L21/027
Filed: 1989-09-04
Abstract: PURPOSE:To make it possible to determine the regularity of pattern arrangement in utmost certainty by a method wherein, when the regularity of pattern arrangement on a substrate is determined, the reliability of positional information of pattern is utilized. CONSTITUTION:A plurality of chips C are aligned on the prescribed reference position successively by determining the regularity of chip arrangement on the wafer W on which a plurality of chips C are formed in matrix form. At that time, before determination of regularity of chip arrangement based on the arrangement coordinate value and the actually measured coordinate value of arrangement, the reliability pertaining to the measured arrangement coordinate value is computed, and the computed reliability is applied to the determination of conversion parameter. Accordingly, the effect of positional information of low reliability given to the computation of conversion parameter is small when compared with highly reliable positional information. As a result, the regularity of chip arrangement can be determined in a highly precise manner without lowering the throughput.

IPC: H02J7/16
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To suppress sudden fluctuations in engine rotation due to load fluctuations of a generator during output switching by switching an output transfer switch in a state of a low voltage control by the control with gradual increase/decrease of a field current when transferring the output of the generator to batteries or a high voltage rolling stock electric load. SOLUTION: In a battery charging mode, an output transistor 305 interruptedly controls a field current flowing through a field coil 102 continuously thereby adjusting the terminal voltage of a battery 4 to a predetermined value. Next, if DUTY-voltage transducer 361 detects a signal showing a voltage operation mode lower than an ECU 8, the conducting percentage of the output transistor 305 decreases at a certain time constant, and a peak voltage of an armature winding 101 is adjusted to other predetermined value. Under this state, an output transfer switch 71 is switched from a battery 4 side to a side of the electric load 5 of high voltage rolling stock by the signal from the ECU 8, and shifting to a high voltage operation mode occurs by the duty control signal from the ECU 8 after the switching.
