Title: Hologram reproduction device, manufacture of angle multiplication hologram and angle multiplication hologram
Inventor: SHIMIZU YUKITAKE
IPC: G03H1/26
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a reproduction device which does not make mechanical driving such as turning of a mirror and reduces the size over the entire part of the device as a hologram reproduction device. SOLUTION: A spatial eight modulator 460 has pixels 461, 462... at the same pitch as the pitch of a diffraction element panel 410. The parallel light beams 470 from a light source are controlled by these pixels to irradiate the respective diffraction element 411, 412... so that the diffracted light beams 431, 432... diverging to the hologram regions 421, 422... subjected to angle multiplication on a hologram panel 401 for displaying reproduced images 451 fall onto these regions. Similarly, the pixels of the spatial eight modulator 460 are controlled in such a manner that the light beams fall onto the regions for displaying another reproduced images (the position shifted on the hologram subjected to angle multiplication), by which the another reproduced images are obtd. In this example the nine reproduced images are independently displayed.

IPC: F02D29/02
Filed: 1987-12-29
Abstract: PURPOSE:To suppress the sharp start or sharp acceleration of a vehicle by judging an abnormal state when the holding power value of a steering wheel is outside a prescribed value region and carrying out control so that the driving power an internal combustion engine reduces. CONSTITUTION:A control means 16 consists of an internal combustion engine control part 18 and an automatic transmission control part 20. In the internal combustion engine control part 18, the fuel injection valve 36 of the internal combustion engine, ignition coil 38, and an intake control solenoid valve 40 are controlled on the basis of the detection signals of a variety of sensors 22-34 for detecting the operation state of the internal combustion engine.

IPC: C10C5/00
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To efficiently collect and separate high purity bamboo vinegar suitable for vinegar and other constituents from material including bamboo pyrolysis material. SOLUTION: The pH of the bamboo pyrolysis liquid 1 is previously adjusted to 9-11 before manufacturing bamboo vinegar from the pyrolysis liquid by distillation.

In this way the bamboo vinegar fraction mainly comprising acetic acid and the distillation residue are separated and collected. The solvent soluble parts of the distillation residue are obtained from the residue by adding an organic solvent, extracting the solvent soluble part and collecting.

Title: Pll circuit
Inventor: MASUOKA HIDEAKI
IPC: H03L7/093
Filed: 1993-12-28
Abstract: PURPOSE:To realize a PLL circuit where a lock-up characteristic is higher speed by supplying the reference voltage from a reference voltage generation means to the reference voltage side of a filtering means. CONSTITUTION:When the setting of a frequency division ratio is switched, the switch is adjusted by a gain setting variable resistance 9 so that the gain of a D/A converter 4 may be equal to the gain of a voltage controlled oscillator (VCO) 5. Every time the setting of the frequency division ratio is switched, a capacitor C4 is charged up by the output voltage of a converter 4. As a result, the change of the voltage of the input terminal of the VCO 5 becomes equal to the change of the output voltage of the converter 4. Therefore, because the time to be required for the change of the voltage of the input terminal of the VCO 5 depends on the only time constant determined by the output resistance of the converter 4 and the capacitor C4, the speeding-up of lock-up time can be performed without changing the characteristic of a PLL circuit by reducing the values of the output resistance of the converter 4 and the capacitor C4.
