Title: Metal spraying method
Inventor: YAMANAKA SHIZUO
IPC: B05B7/22
Filed: 1982-03-30
Abstract: PURPOSE:To enable the formation of a metal sprayed film excellent in uniformity in low cost, by making the weaving width of a spraying gun larger than other spraying gun. CONSTITUTION:In carrying out metal spraying while plural spraying guns are woven, the weaving width of a first spraying gun is set to a width same to that of a non-spraying part 5 while the weaving width of a second spraying gun is made slightly larger than that of the first spraying gun. By this mechanism, the spraying film due to the first spraying gun is deposited only to the area 8 of the non-spraying part 5 while the spraying film due to the second spraying gun is shown by areas 9, 9', 9'' and only the areas 9', 9'' are overlapped with an existing spraying film 7. Therefore, spraying loss at the boundary of the existing sprayed part and the non-spraying part is prevented and the sprayed film on the overlapped part can be made thin.

Title: Image pickup device
Inventor: KAWAHARA NORIHIRO
IPC: H04N9/07
Filed: 1995-03-13
Abstract: PURPOSE: To obtain wide-band R, G and B signals from the output of an image pickup element. CONSTITUTION: Signals, i.e., Ye and Cy signals and Mg and G signals, point- sequentially obtained from a CCD 1 are digitized by A/D converters 2, 3 and the digital signals are applied to respective signal synthesizing circuits 6, 7. On the other hand, a part of outputs from the converters 2, 3 are delayed by one field through a field memory 5 and then applied also to the circuits 6, 7. The circuits 6, 7 are respectively constituted of selectors to output Ye, Cy, Mg, and B signals obtained by doubling the number of picture elements in the horizontal direction by interpolating the outputs of the CCD 1 by signals delayed by one field. These Ye, Cy, Mg and G signals are processed by a matrix operation circuit 8 to obtain a Cy, Mg and G signals. Consequently high definition pictures are obtained on the display screens of various multimedia equipments.

Title: Knocking detector for internal combustion engine
Inventor: YAMAGUCHI KIMIAKI
IPC: G01P15/11
Filed: 1979-04-28
Abstract: PURPOSE: To stably detect weak knocking in an entire running range through a simple means, by using a vibration detection unit having a plurality of resonance characteristics to detect vibration in different frequency bands and by cumulatively synthesizing vibration outputs.  
     CONSTITUTION: A knocking detector 2 having a plurality of resonance characteristics is mounted on the cylinder block of an engine 1. A knocking detection circuit 3 amplifies the AC output signal of the knocking detector 2, rectifies the amplified signal as to its half or full waves, divides engine vibration noises in the initial stage of combustion just after ignition in a no-knocking period from a knocking signal in a knocking priod, samples the noise signal and the knocking signal with regard to time or crank angle, detects whether the ratio between the sampled signals is higher or lower than a prescribed value, and judges whether knocking has occured or not. The result of the judgement is applied to an ignition time controller 4 to perform regulation such as delaying of ignition angle by a prescribed value as to knocking occurrence or advancement of ignition angle by a prescribed value as to non-knocking.

Title: Cryogenic type air separating method and plant for forming gaseous oxygen
Inventor: DRAY JAMES ROBERT
IPC: F25J3/04
Filed: 1993-02-19
Abstract: PURPOSE: To generate gaseous oxygen by efficiently evaporating liquid oxygen without significant refrigeration loss by combinedly using a product boiler and a liquid air supplying source. CONSTITUTION: Liquid oxygen is produced by condensing supplied air 100 through indirect heat exchange with liquid oxygen by supplying the air to a product boiler 107, and then, liquid oxygen is produced by supplying the condensed air to a cryogenic distillation system. The produced liquid oxygen is supplied to the boiler 107 and obtained gaseous oxygen 143 is recovered as a product. Then a liquid oxygen supplying source is generated by supplying the product to a liquid oxygen storage tank 620. An excessive amount of condensed air supply 109 is produced by increasing the flow of the liquid oxygen from the liquid oxygen supplying source to the boiler 107 and the flow of the supplied air 100 proportionally to the increased flow of the liquid oxygen and a liquid air supplying source is generated by supplying an excessive condensed air supply 700 to a liquid air storage tank 750. Therefore, the storage of liquid oxygen can be utilized more efficiently so as to reduce the fluctuation of the availability.
