Title: Output controller for motor vehicle
Inventor: KAMIYA HIROSHI
IPC: B60L15/20
Filed: 1991-05-31
Abstract: PURPOSE:To impart travel feeling to a driver by producing fluctuation of rotational speed, similar to that of an internal-combustion engine, in a motor vehicle. CONSTITUTION:A rotation fluctuation signal generating means 121 produces a rotation fluctuation signal, which fluctuates for every revolution of a motor 30, which is then amplified according to the throttle opening. A duty ratio converting means 126 modifies the duty ratio of a signal having predetermined frequency according to a signal having an upper limit set by a limiting means 125. A phase control signal generating means 130 produces a phase signal from an output from a rotor position sensor. A switching means 127 delivers an output signal from the duty ratio converting means 126 to a switch circuit 106 based on thus produced phase signal. Consequently, the motor 30 being rotary driven through the switch circuit 106 produces speed fluctuation similar to that of an internal-combustion engine thus imparting travel feeling to a driver.

Title: Image pickup device
Inventor: YONEYAMA MASAYUKI
IPC: H04N5/378
Filed: 1990-06-14
Abstract: PURPOSE:To obtain high brightness resolution and excellent color reproducibility with simple circuit constitution by obtaining gamma correction information and gain correction information from a signal subject to photoelectric conversion and inputted to a control means so as to adjust the gain. CONSTITUTION:Gamma correction information and gain correction information are obtained from a signal subject to photoelectric conversion by a photoelectric conversion means 2 and inputted to a control means 17 and they are inputted to a gain adjustment means 16, in which gain adjustment is implemented. Since each signal processing such as gain adjustment, gamma correction, color temperature adjustment and clipping is implemented in the lump without being separated into each relevant block, the circuit constitution is simplified, the deterioration in the picture quality due to mixture of noise attended with rounding error and count quantization caused in a conventional system is avoided and high brightness resolution and excellent color reproduction are obtained.

IPC: C21C7/10
Filed: 1988-06-24
Abstract: PURPOSE:To promote the decarburization by providing a splash reducing plate above the molten steel surface directly above the dip riser pipe of a vacuum circulating degasification device to increase the initial exhaustion rate. CONSTITUTION:The refractory discoid splash reducing plate 13 having a flat surface is provided directly above the molten steel 2 surface in the vicinity of the dip riser pipe.

Title: Method and apparatus for digital modulation using sine carrier wave
Inventor: PAURU DAMUBAHAERU
IPC: H04L27/34
Filed: 1994-06-03
Abstract: PURPOSE: To reduce average transmission required power to a minimum by arbitrarily selecting the position of an amplitude/phase state on a vector diaphragm corresponding to an optimization judgement standard in the digital modulation of a sine carrier wave. CONSTITUTION: In the modulation of a single carrier wave, the output of a sine wave generator 1 is sent through plural networks N1-Nn to a switch 2. a1 , ϕ1 to an , ϕn , corresponding to amplitude and phase states are set to the respective networks. At this time, the positions of amplitude and phase states on the vector diaphragm are set, so as to minimize the average transmission required power with the size of discrimination circle as a maximum within a fixed determined modulation limit. On the other hand, a data stream is divided into tribits and corresponding to the tribits, a processor 3 drives the switch 2 and selects a network. Thus, since the respective amplitude and phase states allocated for each tribit are sent out successively, the transmission required power can be minimized.

Title: Compression molding device
Inventor: KANI KAZUYOSHI
IPC: B29C43/32
Filed: 1985-07-16
Abstract: PURPOSE:To enable the proceeding condition for molding a material to be confirmed at its processing stage by providing the light emitting part capable of being. inserted into a mold and the light receiving part receiving the light emitted from said light emitting part. CONSTITUTION:When the material 4 to be molded is inserted into between heating plates 5, 6, and then is heated and pressurized, the material is commenced to be smoothed along the surface of the heating plates 5, 6. A part of the light emitted from LED array 10 is reflected on the unsmoothed part, and is received in an one dimensional image sensor 11. When the material 4 is smoothed, the scattering on the unsmoothed part of the material 4 is reduced, and the reflection is increased, whereby reflected light amount is increased. By this process while placing LED array in parallel with the one dimensional image sensor, and further utilizing the linearity between the light amount received in the one dimensional image sensor and the output, the unsmoothed part of the material 4 may be detected. Accordingly, when the reflection index is increased at every position of the material, it may be confirmed that molding is finished.

Title: Color developable recording material
Inventor: ENOTANI MASASHI
IPC: C09B21/00
Filed: 1987-06-25
Abstract: PURPOSE: To enhance the light fastness of an image, by incorporating a specific substance in an image part formed from a fluorane compound type color forming dye and a coupler.  
     CONSTITUTION: A phenothiazine compound is contained in an image part constituted and formed of a fluorane compound type color forming dye and a coupler. In the color developable recording material like this, when the dye developed by the action of the coupler and a small amount of a phenothiazine compound coexist, the fading of the developed dye is markedly lowered and the durability of the developed color is enhanced. Since the phenothiazine compound imparts no adverse effect on the action of the fluorane compound or coupler even when brought into contact with the undeveloped fluorane compound or the coupler, the phenothiazine compound is preliminarily mixed with one of or both of the color forming dye and the coupler or placed in a phase different from the color forming dye and the coupler to be mixed with both of them in such a stage that the color forming dye and the coupler are brought into contact with each other.
