Title: Color image pickup device
Inventor: FUJIMOTO MAKOTO
IPC: H04N9/45
Filed: 1981-10-07
Abstract: PURPOSE:To easily correct a chrominance signal even when a circuit is constituted in the form of a united IC, by regulating a subcarrier to be applied to an encoder by a color correcting signal generated from a luminance signal or color signal. CONSTITUTION:A signal from an image pickup tube is sent to a color separating circuit through a preamplifier, which extracts luminance signals YH and YL, a red signal R, and a blue signal B. Those signals are passed through a process circuit, an encoder, and an MIX circuit in an integrated circuit LSC to obtain a composite video signal. A subcarrier generating circuit generates a subcarrier frequency to input 90 deg. out-of-phase signals SS1 and SS2 to the encoder ENC. In this case, a synthesizing circuit COMP and a correcting signal generating circuit CSP generate a color correcting signal CS from at least one of the luminance signals and color signal. This signal CS is inputted to a correcting circuit to correct the amplitude and phase of the subcarrier.

Filed: 1977-12-26
Abstract: PURPOSE:To measure the quantity of reflected light reflected by the measuring object and made  possible measurement of the refractive index and other optical characteristics of the measuring  object from the quantity of reflected light by using a branching coupler constituted by optical  fibers. CONSTITUTION:The light of a light source 11 passes through an optical fiber 12 and is divided to  two in a branching coupler 13. One is led into measuring liquid 14 for refractive index via fiber  12' and the other into a photo detector 15 via fiber 12''. Now, with the refractive index of the core of the fiber 12' being let to be (nc) and the refractive index of liquid of an unknown refractive  index to be (nx), the light is reflected at the boundary of the core of the fiber 12' and the liquid 14 and arrives at the coupler 13 through the fiber 12', from where it is branched and goes backward.  This light then goes through the fiber 12''' and reaches a detector 16, whose output is processed  together with the output of the detector 15 in an amplifying operator 17, thence in a meter 18 the  refractive index (nx) related to quantity of reflection R by the nx = (1 - R<1/2>)nc/(1 + R<1/2>)  formula is displayed. Various optical characteristics of the measuring object may be rapidly and  readily measured by using the simple optical branching coupler.

Title: Shaft seal for hydraulic machine
Inventor: HAZAKI EIICHI
IPC: F04D29/10
Filed: 1989-06-26
Abstract: PURPOSE:To prevent blow-by of fluid to be sealed with improved sealing property by causing the tip of a seal member made of laminated flexible fibers to tilt toward a higher pressure side so that the fiber tips projecting out of a support member come in contact with a rotary shaft. CONSTITUTION:Fibers 11 are secured by tightening support members 12, 13 with a bolt 14. The tips of the fibers 11 projecting out of the support members 12, 13 are in contact with a shaft 1. The fibers tilt to a higher pressure side to greater degrees toward their tips. Each of the fibers 11 receives pressures from higher and lower pressure sides. The differential pressure is assumed to be  P1. As the fiber 11 is tilted more toward its tip to the higher pressure side, a component force  P1n vertical to the shaft 1 surface is exerted on the fiber 11 to press the tip of the fiber 11 against the shaft 1 surface. Therefore, steam is prevented from blowing through from an exhaust chamber 8 to the lower pressure side, resulting in improved sealing property and turbine efficiency.

Abstract: PURPOSE:To reduce the error after analog conversion and to attain highly accurate analog output wit a desired range by providing a C-MOS logic circuit, an averaging means and a level conversion means or the like so as to reduce the adjustment range of a zero span point. CONSTITUTION:A PWM signal S having a prescribed duty ratio range inputted to a pulse width modulation(PWM) signal output means 1 is inputted to a C-MOS logic circuit 3a in a D/A conversion means 3 via an isolation means 2. In this case, a voltage signal in a range of Vref-Vref-0.1V or 0-0.1V is outputted to an averaging means 3b depending on the off/on state of a transistor(TR) of a photocoupler in the means 2. The means 3b applies averaging processing to an input voltage signal and outputs the result to a level conversion means 3c, where the zero span point of the input voltage signal is adjusted and the analog signal with a desired range is outputted. Thus, the adjustment range of the zero span pint is decreased to reduce the error after analog conversion and the analog signal with high accuracy in the desired range is outputted.

Abstract: PURPOSE:To provide the method for evaluating photomask patterns capable of adequately evaluating the normal/defective condition of patterns for transfer formed on a photomask to be used at the time of executing exposure by using an exposure device provided with a function to correct the transfer patterns and its device as well as the pattern transfer method utilizing the method for evaluating the photomask pattern. CONSTITUTION:Actually measured coordinate data are determined by measuring the coordinate values of the positions at >=2 reference points in the patterns formed on the photomask 1 by an instrument 2 for actually measuring the coordinate values. Next, both data are compared by a function 3 of a computer 100 to determine the relative positions of the actually measured coordinate data and design coordinate data.

Whether the individual deviations of both data in the positions where the relative positions are determined are within a permissible range or not is then evaluated by the deviation determining function 4 of the computer 100.

Title: Motor drive circuit
Inventor: MURASE MAKOTO
IPC: H02P6/24
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To enhance follow-up function in the deceleration of a motor drive circuit by the PWM control scheme. SOLUTION: The motor drive circuit comprises an exciting pulse generation circuit 1 which generates and outputs PWM control signals for controlling the revolution of a motor 6 containing motor input terminals 8 and 9 in correspondence to the motor 6, switch (S1) 2, a switch (S2) 3, a switch (S3) 4 and a switch (S4) 5 which are formed of a MOS transistor or Bip transistor and ON/OFF-controlled by the PWM control signals, respectively, and a VM terminal 7 which supply voltage is applied. When the switch (S3) 4 is OFF and the switch (S4) 5 is ON, the motor 6 is rotationally driven. When the switch (S3) 4 is OFF and the switch (S4) 5 is ON, the motor input terminals 8 and 9 are short-circuited and regenerative current is produced by the electromagnetic induction of the armature.  As a result, rotational speed is reduced, and thus the follow-up capability in the deceleration for the motor 6 is enhanced.
