Patent JP-H11242197-A (JP)
Title: Projection display
Inventor: MURAKAMI OSAMU
IPC: G02F1/13
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To propose a constitution advantageous for miniaturization of a single- plate reflection type projection display. SOLUTION: A liquid crystal shutter 5 as a projection light color switching means in a projection display 1 is provided with a first guest host layer 15 which can absorb a red luminous flux R, a second guest host layer 16 which can absorb a green luminous flux, and a third guest host layer 17 which can absorb a blue luminous flux B. When turning-on/off of supply voltages to these guest host layers is controlled to set the first guest host layer 15 and second and third guest host layers 16 and 17 to the transmission state and the light absorption state respectively, only the red luminous flux R is emitted from the liquid crystal shutter 5. Since the liquid crystal shutter 5 functions as a projection light color switching means in this manner, it is unnecessary to rotate and drive color filters by a motor.  Therefore, mechanical mobile parts are eliminated to considerably contribute to miniaturization of the display.

IPC: G06T7/60
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To simply execute the discrimination of a characteristic of image data such as edge separation by using compressed data. SOLUTION: Input image data is given to an image separate section executing image area separation separating characters and patterns and edge separation discriminating an edge part and a non-edge part and to a gamma transformation section 32 applying processing to data. A gamma coefficient in the gamma conversion section 32 and a filter in a filter section 33 are decided and compression data of block coding generated by a coding decoding section 5 are used to generate an area signal by an area signal generating section 10, and it is outputted to a pseudo medium to one processing section 9 via a FIFO 11. Area data are data for each block consisting of n×n picture elements.  Since the coded data are stored in a memory, the memory for image data having been used for generating a conventional area signal is not required, the cost is suppressed and the entire configuration is simplified.

Title: Compressor
Inventor: ONODA TADAYUKI
IPC: F04C28/10
Filed: 1982-03-23
Abstract: PURPOSE:To enale to control the refrigerating capacity of a compressor at the time of its high-speed operation, by appropritely selecting and combining parameters such as the suction area, the discharge quantity, the number of vanes, etc., eliminating interference between two vane chambers at the time when the suction stroke is just finished, and keeping the effective suction area constant during the suction stroke. CONSTITUTION:A 4-vane type compressor of this invention is designed such that the effective suction area of a suction port 15 is equal to that of another suction port 17. Therefore, the effective suction area of an intake passage extended from a coolant supply source to a vane chamber 18-1 is kept always constant during the suction stroke. Further, since the compressor of this invention has two suction ports 15, 17 as shown in the drawing, coolant is drawn into the vane chambers 19-1, 18-2 and 18-3 independently from either of the two suction ports 15, 17 without causing interference between them. Therefore, it is enabled to prevent deterioration of the capacity cotrolling characteristics due to increasing in the number of the vanes and to control the refrigerating capacity correctly at the time of high-speed operation of the compressor.

If the image recording is still continued, the recording sheet 7 is discharged in a loop-like shape from the device body due to the rotation of the pair of discharge rollers 28, 29. The storage tray 14 does not project from the device body.

IPC: H05K3/28
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent an electronic component mounting land from peeling, and to allow coating of a cream solder which requires no solder mask. SOLUTION: An insulating layer 3 of thickness of 20 μm or more from a land 2 surface is so formed as to cover the entire peripheral edge part of the land except for the central part of the land from the board surface with a part of the land overlapped. Thus, even if the peel strength of the land 2 is weak, reinforcement is made for retarding peeling. When, especially, the insulating layer is formed in thickness of 100 μm or more, the insulating layer is used instead of a solder mask to coat a cream solder on the printed board.

Title: Additive for fuel oil
Inventor: KAI AKIO
IPC: C10L1/12
Filed: 1989-02-27
Abstract: PURPOSE:To obtain an additive for fuel oils which effectively inhibits the production of unburnt carbon without deteriorating a denitrifying catalyst which is arranged on the downstream side of combustion equipment by mixing iron or an iron compound and an amorphous carbon. CONSTITUTION:An additive for fuels is obtained by mixing iron or an iron compound (e.g. iron colloid, iron hydroxide, or bis-acetylacetonedipyridine iron complex) and an amorphous carbon (e.g. ultrafine carbon black). The blending ratio (by weight) of the iron to the amorphous carbon is 1/99-90/10, and the amount of the addition of the additive to a fuel oil is generally 100-1,000ppm. When the additive is blended with a fuel oil, an unburnt carbonized tissue is changed to a mosaic structure which is easily burnt without deteriorating a denitrifying catalyst which is arranged on the downstream side of combustion equipment, and also the burnout temperature of the fuel oil can be lowered, so that the amount of unburnt components in the exhaust gas is effectively reduced. Therefore, the load on the equipment such as a dust collector or a denitrifier which are additionally connected to a combustion plant can be reduced or their life can be prolonged and measures against problems including environmental pollution can be taken.

This double wave signal is sent to a first peak detection circuit 2, and when an output signal of this first peak detection circuit 2 used as a reference, the polarity of the signal is inverted in an inverter circuit 3. This polarity-inverted current Ib is converted into an extrusion current Ib' of 1/2 by a current mirror circuit comprising PNP transistors TR Q14 and Q15, and it is added up with a double wave rectified current Ia obtained from an output TR Q9 of the double wave rectifier circuit 1. A current Ia+Ib' obtained by this addition is subjected to peak detection by a second peak detection circuit 4. By the detection by this second peak detection circuit 4, a ripple component can be reduced sharply.
