Title: Calibration method for color enlarger
Inventor: SUGANUMA YOSHIMI
IPC: G03B27/46
Filed: 1987-10-23
Abstract: PURPOSE:To perform calibration without preparing a standard are frame by storing values, which are obtained by subtracting density values of corresponding colors of a base from respective color density values of red, green, and blue of the standard frame, as fixed data in a memory. CONSTITUTION:Calibration is performed without expensive standard frames such as a normal standard frame, an over standard frame and an under standard frame, and density values obtained by subtracting density values of corresponding colors of an unexposed part (the base) from respective color average density values of red, green, and blue of the standard frame are stored as fixed data in the memory. At the time of calibration, the light of the unexposed part of a photographic film is measured to obtain respective density values of red, green, and blue and fixed data read out from the memory are added to these density values to obtain three-color density values of the standard frame. Since base density values obtained by actual measurement are added to fixed data in this manner, it is unnecessary to prepare the standard frame.

Title: Mixing device
Inventor: OKABE YASUSHI
IPC: B01F15/04
Filed: 1984-12-18
Abstract: PURPOSE:To realize mixing of multiple components such as petroleum fractions, etc., with good precision and specified proportion by providing a pressure regulating valve to a referential line and reducing the flow rate by reducing a set pressure of the referential line when the degree of opening of a flow control valve provided to a follow-up line attains above a specified value. CONSTITUTION:When the amt. to be used from the pipes 15, 16 for the outside of the system is little (for this case, the primary side pressures of the A component line and the B component line are sufficiently high), or when the number of delivery port 9 during use is small, the pressure in a header pipe 7 is held easily at a standard pressure, for example at 2kg/cm<2>.G. Thus, the proportion of the flow rate of the component B to the flow rate of the component A is held at a desired value, so the delivery work is performed normally. Even if the primary side pressure of the A component line or the B component line is higher than the pressure of this condition, the number of the delivery port during use becomes less, the header pressure is held at a specified level, so the delivery work is performed normally.

Title: Liquid crystal electro-optical element
Inventor: OKUMURA OSAMU
IPC: G02F1/133
Filed: 1989-10-16
Abstract: PURPOSE:To obtain the optical element which causes no decreases of the transmitted light quantity even if the density of a circuit element is increased by setting a liquid crystal to torsion orientation of 90 degrees, and also, providing a prescribed selective reflecting member. CONSTITUTION:In a liquid crystal cell in which a liquid crystal is set to torsion orientation of 90 degrees, one selective reflecting member 2 (polarized light beam splitter PBS) is arranged instead of two pieces of polarizing plates. An S polarized light 53 which is made incident from the A direction and bent orthogonally by the PBS 2 is emitted in the state of an S polarized light 56 as it is. On the other hand, when a voltage is applied to the liquid crystal cell, the S polarized light 53 is emitted in the state of a P polarized light 55, and the P polarized light travels straightly without being influenced by the PBS 2 and emitted in the B direction. In such a manner, by a reflection mode combined with the PBS 2, turn-on and turn-off can be executed with a high contrast, and a bright display can be obtained.

Title: Light transmission body device for increasing polarized light component and liquid crystal display device
Inventor: SUZUKI MASARU
IPC: G02F1/1335
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To take out one polarized light component of a light transmission body which allows the transmission of one of the polarized light components and takes out the same with high conversion efficiency and to efficiently direct the taken out polarized light component to a liquid crystal cell. SOLUTION: The light of a light source is made incident on the light transmission body consisting of many light transmission body layers and the polarized light component reflected at its end face heads toward the boundaries of the light transmission body layers. The polarized light component transmitted through the end face is rotated in the plane of polarization and is reflected by a wavelength plate and reflection plate. The reflected light is made incident again on the light transmission body from the end face of the light transmission body and heads toward the boundaries. Since this light is rotated in the plane of polarization, much thereof transmits the boundaries. The reflected polarized light components are returned to the wavelength plate and the reflection plate and again advance toward the boundary of the light transmission body.  The polarized light component transmitted through the boundary is similarly transmitted and reflected at the next boundary. The number of the boundaries may be decreased by enhancing the reflectivity of the polarized light components reflected at the boundaries. The refractive indices of the light transmission body are, therefore, made anisotropic, by which the refractive index in the direction along the axis of the polarized light component to be reflected is made larger.

Title: Output circuit for semiconductor integrated circuit
Inventor: MIYAGAWA HARUKO
IPC: H01L21/8234
Filed: 1987-10-24
Abstract: PURPOSE:To prevent malfunction of an internal integrated circuit due to noise by clamping a signal level fed to a gate of a PMOS and NMOS transistors(TRs) to a prescribed value so as to prevent a large current from flowing to both the TRs thereby suppressing the fluctuation of 1st and 2nd power supplies. CONSTITUTION:With an input terminal 1 going to 'L', for example from the steady-state where the level of input/output terminals 1, 5 at 'H', since a gate of PMOS and NMOS transistors(TRs) 6, 11 reaches 'H', the TR 6 is turned off and the TR 11 is turned on and an output terminal 5 transits to a low level. Then the gate of NMOS TRs 12-15 go to 'H' and the TRs 12-15 are all turned on. Thus, the gate voltage of the TR 11 clamped to a voltage level slightly lower than the power voltage level VDD. Thus, the current flowing to the output TR 11 is reduced more than that when the gate voltage is high suppress the discharge from the load capacitor such as the wiring. Thus, an instantaneous large current flowing to the output TRs 6, 11 is reduced.

IPC: B60W10/12
Filed: 1987-10-24
Abstract: PURPOSE:To eliminate early the slip condition of wheels by distributing much torque to wheels having no slip when a difference in the rotational difference between front and rear wheels takes place and throttling to reduce the output of an engine when a plurality of wheels slip. CONSTITUTION:The output of a transmission 2 is distributed to front and rear wheels by a center differential gear 3, while a portion of torque for the front wheels is distributed to the rear wheels through a hydraulic multiple disk clutch 6. A torque split controller 100 is provided which receives the output signals of various sensors for detecting the running conditions. This controller 100 generates a clutch controlling signal for controlling the torque distribution on the basis of a difference in each average rotational frequency between the front and rear wheels. Thus, the clutch 6 is controlled to distribute torque to the front and rear wheels having no slip while a throttle opening controlling signal is generated to throttle the opening of a throttle and reduce the output of an engine when slips on at least three wheels are detected.
