Title: Light interference angular velocity member
Inventor: OKADA KENICHI
IPC: G01C19/72
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To improve the linearity as an input-output characteristic by adding a construction wherein the frequency of a reference signal for synchronous detection of an electric signal obtained by detecting the light intensity of interference light is changed in a vibratory manner. SOLUTION: A system clock generating means 30 is constructed of a voltage control oscillator. A voltage control input terminal 30A thereof is supplied with a control voltage changing at random, for instance, from an external signal generating means 31 and the frequency fm of both of a reference signal VR and a phase control signal VC outputted from the system clock generating means 30 are changed at random. Since the frequency of the reference signal VR is varied in a vibratory manner by the output of the external signal generating means 31, the probability of coincidence of a frequency fR of a sawtooth wave Ra of a feedback signal with the frequency fm of the reference signal VR is low and the amount of a scale factor error lessens. The scale factor error changes to the positive and negative sides and it is canceled by the positive and the negative in an average.  Accordingly, the value of the scale factor error is reduced sharply.

Title: Formation of mask absorber film for x-ray exposure
Inventor: YOSHIOKA NOBUYUKI
IPC: G03F1/22
Filed: 1987-03-20
Abstract: PURPOSE:To obtain an X-ray absorber pattern film having low internal stress by a Ti-W alloy film with excellent reproducibility by shaping the Ti-W alloy film through a sputtering film formation method using a reactive gas, in which nitrogen gas is added to argon gas, and mixing nitrogen into the Ti-W alloy film. CONSTITUTION:An X-ray absorber pattern film material employing a Ti-W alloy containing Ti is sputtered by a reactive gas, to which Ar gas and N2 gas are added, thus forming a film. The quantity of nitrogen gas mixed into argon gas is kept within a range of 30%-50% at that time. That is, when a Ti-W alloy film is shaped onto a mask substrate through a sputtering film formation method, N2 is mixed into the Ti-W alloy film by using the reactive gas in which N2 gas is added to Ar gas, thus forming an X-ray absorber pattern film by the Ti-W alloy film having an excellent absorption coefficient and low internal stress with superior reproducibility.

Filed: 1988-03-19
Abstract: PURPOSE:To increase number of light emitting diodes able to be driven by a microcomputer considerably by providing a shift register between an input/ output device and a buffer amplifier for current amplification. CONSTITUTION:A microcomputer 1 implements processings such as transmission/ reception of an external signal, generation of a character or signal generation of a graph desired to be displayed or the like and sends the result to an input/ output device 2.

The shift register G has a latch function and parallel output is attained at once by the latch function at a point of time when the signal transmission is finished. The parallel output is sent to a buffer amplifier 3 and the light emitting diode is driven. The time required for the signal transmission of the shift register 6 in this circuit gives effect on the scanning time and it is sufficiently coped with the processing speed of the existing microcomputer and up to 1000 small sized circuits are sufficiently driven even by the microcomputer whose speed is not so fast.

Title: Jet pump
Inventor: OKAMOTO YOSHIHARU
IPC: F04F5/44
Filed: 1983-04-15
Abstract: PURPOSE:To uniformize the flow speed of a fluid at the section in a tube and eliminate cavitation by arranging electrodes for electrolysis on the inner walls of communicating parts between a suction tube and a delivery tube. CONSTITUTION:A high pressure fluid is injected into the delivery tube 2 from a high pressure injection tube 3 under a condition that the suction tube 1 is communicated within the electrolytical fluid such as seawater or the like to form a jet stream. The fluid in the suction tube 1 is flowed through the delivery tube 2 together with the jet stream by a pressure difference generated by the jet stream. In this case, when the electrodes 5 for electrolysis, which are arranged on the inner walls of the tubes 1, 2, are conducted, minute bubbles are generated by the electrolysis, the bubbles surround the periphery of the fluid, the fluid is afloated from the inner wall of the tube and thereby reducing the flow resistance of the fluid remarkably.

Title: Water-expansion type flexible film rising and falling dam
Inventor: MARUYAMA ICHIROU
IPC: E02B7/20
Filed: 1983-04-16
Abstract: PURPOSE:To obtain an useful tide embarkment by a method in which the internal pressure of a flexible film rising and falling dam is specifically designated and the variation in the heights of the dam with the variation in the water depth of up and downstreams is lessened. CONSTITUTION:In a flexible film rising and falling dam, under the condition of upstream water depth=height of dam and downstream water depth=0, the internal pressure P0 of the bottom of the dam is controlled to 1.6<=P0/H0<=2.0, where H0 is the basic height of dam. Since the variation in the dam height with the variation in the water depth of up and downstreams is small, the frequent falling of the dam by small-scale flooding can be avoided, and the overflow vibration of the dam in a high-overflow state can also be avoided. The dam is thus useful for tide embarkment in places where the water depth of downstream is varied.

Title: Transmission for control
Inventor: TAKAHASHI TAKASHI
IPC: F16H3/44
Filed: 1986-03-26
Abstract: PURPOSE:To permit the correct transmission by adjusting the shift of the half of the intermediate shafts clockwise and the half of the intermediate shafts counterclockwise under the stop of revolution of the sun gear and the internal gear of a transmission consisting of a star type or planetary gear type mechanism and locking the intermediate shafts, thus permitting the backlash to be eliminated. CONSTITUTION:A sun gear 5 and an internal gear 7 are locked, and the connecting rods 10 and 10 of the intermediate shafts 9a and 9b are revolved in the F-direction, and the rods 10 and 10 of the intermediate shafts 9c and 9d are revolved in the G- direction up to stop. Though the revolution of each intermediate gear 8a-8d becomes the revolution around the axis center of the rod 10, said revolution can be regarded as the revolution in the circumferential direction around the axis center of a gear 5, in a small range of the backlash corresponding distance, and the gears 8a and 8b revolve in the F-direction, and the gears 8c and 8d revolve in the G-direction, and the gears 5 and 7 stop at the position where the contact with each tooth flank eliminates the backlash. When the rod 10 is locked, and the lock of the gears 5 and 7 is released, the revolution direction is switched in the state where the backlash is zero, and the correct transmission free from the generation of delay of revolution is permitted.

Title: Image processing method
Inventor: OUCHI SATOSHI
IPC: H04N1/40
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of picture quality by avoiding erroneous discrimination by separating image areas more than twice at least, making a parameter for discriminating an original based on the first image area separation discrimination different from a parameter for locally discriminating the areas at the time of main scan, and utilizing only the high-certainty information when discriminating an original. SOLUTION: A parameter storage part 9 stores the 1st parameter for the time of prescan and the 2nd parameter for the time of main scan. At the time of prescan, only an edge separator circuit 10 is operated and an edge is detected while using the 1st parameter with which it is difficult to detect the edge. A decision circuit 11 decides an original image and counts the edges. When that value is more than a prescribed threshold value, it is decided that the original contains characters, and the result is stored 14.
