Title: Disk chucking device
Inventor: SATO NOBUKATSU
IPC: B25J15/08
Filed: 1988-05-12
Abstract: PURPOSE:To stably perform the chucking of a disk by facilitating the adjustment of a chuck roller and abutting all of the chuck rollers with the disk by moving a sliding block by a driving means at the time of chucking the disks with different diameters. CONSTITUTION:In case of chucking the disk 7' with a small diameter, a cam plate 10 linked to a rod 9a is descended in a direction of arrow head A by operating a cylinder 9 and extending the rod 9a. A cam follower 13 mounted on a plate 12 is transferred along the cam plane 11a of a groove cam 11, and the sliding block 5 is moved in a direction of arrow head B, and a state as shown in alternate long and short dash line is generated, and as a result, the interval between right and left chuck rollers 8, 8 is reduced, thereby, the disk 7' with the small diameter can be chucked. Therefore, even in such case, since a turning angle between the chucking position and the chuck releasing position of a turning arm 1 is equal to that of the disk 7 with a large diameter, it is not required to adjust the position of the chuck roller 8, etc.

Title: Axial flow turbine blade
Inventor: UCHIDA SUMIO
IPC: F01D5/12
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To convert flow of a laminar flow boundary layer into flow of a turbulent boundary layer by arranging a plurality of small projections within the laminar flow boundary layer on both up/down wall surfaces for supporting both ends of a blade. SOLUTION: A plurality of cylindrical or polygon small projections 7 are arranged on a laminar flow boundary layer 4 enclosed by the broken line on a ring wall surface 2, whose height is set to about 1/10 comparing with that of a boundary layer, its some of the appropriate number are distributed and dispersed on a suitable position in the laminar flow boundary layer 4, turbulence is induced on flow which abuts on the small projections 7, and the laminar flow boundary layer 4 is converted into a turbulent boundary layer. Since the shearing abrasion coefficient of the turbulent boundary layer is smaller than that of the laminar flow boundary layer, frictional force between a wall surface and flow converted from the laminar flow boundary layer into the turbulent boundary layer is reduced by the small projections 7.  It is thus possible to reduce energy which may be lost by flow, and it is also possible to improve blade performance.

Title: Compact vessel
Inventor: YUZUHARA YUKITOMO
IPC: A45D33/00
Filed: 1991-04-19
Abstract: PURPOSE:To provide a compact vessel capable of preventing the fall of a pin from a hinge part and highly improving the assembling property. CONSTITUTION:A first protruding part 36 formed on a vessel body 12 and a second protruding part 38 formed on a lid body 14 are superposed and disposed. A pin through hole 44 for inserting a hinge pin 40 is formed between the first protruding part 36 and the second protruding part 38.

Title: Semiconductor device and light wave communication system
Inventor: TOOMASU ERU KOTSUFU
IPC: H04B10/00
Filed: 1991-04-19
Abstract: PURPOSE: To obtain a semiconductor device in which a signal from means for generating a first optical wave signal can propagates through means for detecting a second optical wave signal by arranging a means for generating a first optical wave signal and a means for detecting a second optical wave signal on a same line along the longitudinal axis of waveguide section. CONSTITUTION: In order to prevent transmission of light of shorter wavelength of 1.3 μm from reaching a detector for longer wavelength of 1.5 μm and of a signal of shorter wavelength is detected, a short wavelength absorbing region 204 is arranged between a 1.3 μm transmitter and an 1.5 μm detector. Consequently, a 1.3 μm optical wave signal emitted rightwards from a photonic integrated circuit is also absorbed, before reaching the next longitudinal part of the photonic integrated circuit including a long wavelength absorbing layer. Consequently, a receiving optical wave signal of along wavelength can pass through the absorbing region with no loss, and thereby it can propagate through means for detecting a second optical wave signal.

Abstract: PURPOSE:To improve the antileakage property by insulating between a negative electrode terminal bottom plate and a metal washer or insulating between the metal washer and a nylon sealing body. CONSTITUTION:By coating a metal washer 8 with an insulating coating membrane 13, no liquid leakage is generated even though a cell is stored under a high humidity ambiance and the moisture in the external air reaches the clearance 12 between a resin sealing body 10 and the metal washer 8 passing through gas release holes 7 and 9, since the contact surface between a negative electrode terminal bottom plate 6 and the metal washer 8 is insulated electrically. By insulating between the negative electrode terminal bottom plate 6 and the metal washer 8, between the metal washer 8 and the nylon sealing body 10, or between the nylon sealing body 10 and the electrolyte in such a way, a liquid leakage phenomenon of the cell in the storing of the alkaline dry cell under a high humidity ambiance can be prevented.

Title: Erasing device for magnetic recording
Inventor: MINOURA NOBUO
IPC: G11B5/024
Filed: 1986-05-19
Abstract: PURPOSE:To satisfactorily erase a recorded signal in a wide range by recording a prescribed erasure signal from an erasure signal generation part in a necessary area. CONSTITUTION:A signal switching part 200 is controlled through a control part 400, and the erasure signal from the erasure signal generation part 100 is supplied to a signal recording part 300 instead of a recording signal. Recording is executed by the erasure signal whose oscillation frequency changes according to a prescribed voltage value that the generation part 100 outputs signals in areas outside a recording area from a position outside the signal recording area in a prescribed circular track via the recording area, and whose current value gradually decreases as the oscillation frequency rises in a prescribed time. Thus, the signal recorded in the necessary area is satisfactorily erased, and residual recorded erasure signals do not influence the second PCM recording. Consequently, the recorded signals are satisfactorily erased in a wide range.

Title: Rotary valve
Inventor: SHIMOGAMA HIRONORI
IPC: F15B13/044
Filed: 1991-05-20
Abstract: PURPOSE:To prevent an abnormality or an accident in a hydraulic system and facilitate adjustment in a neutral point by positioning a movable part comprising a valve body and a rotor by applying force to the part in the circumferential direction and so returning the valve body to a predetermined position when the driving means is disconnected. CONSTITUTION:A part of a movable part comprising a valve body 1 and a rotor 6 in a rotary valve is connected integrally to such a solid part as each casing 2, 3 or a magnet 7 by means of a spring. Accordingly, due to restoring force of the spring, the valve body 1 or the rotor 6 is returned to a predetermined position, thereby positioning it. For example, the valve body 1 and the casing 3 are connected together integrally with a coil spring 22. When the input to the rotary valve is disconnected, the valve body 1 is thus returned to a predetermined position from its displacement position by means of tensile force or restoring force of the coil spring 22. Therefore, an accident in a hydraulic system which is caused by only the fluid force of working oil acting on the valve body 1 at the time of power failure or input line disconnection can be prevented.

Abstract: PROBLEM TO BE SOLVED: To improve the judging precision of day/night and to improve the recognition precision and the monitoring precision of an object by judging day/ night from a luminance average in a prescribed designation area and recognizing the object through the use of an image processing technique different between day/night. SOLUTION: An image input part 1 fetches an image photographed by an image pickup device such as a monitor camera installed outdoor as a monitor image and temporarily stores it in an internal image memory. A luminance detection part 2 obtains the luminance of each pixel within a designated area previously fixed from among the monitor image stored in the image memory and obtains a value obtained by dividing the total sum by the number of pixels within the designated area. A day/night judging part 3 judges day/night from the luminance average obtained by the luminance detection part 2. A day-time recognition part 4a and a night time recognition part 4b image-processes the monitor image stored in the image input part 1 by using image processing techniques different between day/night based on a judging result at the day/night judging part 3 and recognizes the object.
