Title: Binarized threshold level decision system
Inventor: KOTAKI KENJI
IPC: G06T1/00
Filed: 1993-05-11
Abstract: PURPOSE:To provide the binarization threshold level in which a processing time for deciding a threshold level is reduced and misdetection of a threshold level is prevented. CONSTITUTION:A histogram representing a frequency for each density level is generated from picture data quantized by a histogram generator of a picture processing unit (not shown). A maximum value f(Z1) with a frequency corresponding to a background, a maximum value f(Z2) with a frequency corresponding to an object and maximum values fa, fb due to noise are in existence in the histogram. A search area lower limit alpha1 and a search area upper limit beta1 are set to a controller for a picture processing unit externally. Then an area between the search area lower limit alpha1 and the search area upper limit pi is used for a search area and the controller decides a threshold level for binarization within the area.

Title: Recording head, recorder using the head, and recording head cartridge using the head
Inventor: KOMURO HIROKAZU
IPC: B41J2/01
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a recording head for detecting a connecting fault between the head and a recorder and the recorder using the head without lowering reliability of electric connection of the head to the recorder without increasing a cost of the recorder. SOLUTION: In the case of mounting the recording head at the carriage, a sheet resistance of a resistor of the head is measured from a resistance value between a Vss terminal and a Rank terminal. Further, a control signal (block enable signal) for generating a block selection signal is input from a terminal to drive an NMOS transistor 307. Then, overall resistance of the ON resistance value of the transistor and the sheet resistance value is measured from a resistance value between the Vss terminal and Rank terminal. An electric connection of an electric contact of at least the recorder to the Vss terminal and Rank terminal of the head is confirmed according to the measured result.

Title: Rectilinear pattern detecting device
Inventor: KENBOU YUKIO
IPC: G01B11/00
Filed: 1978-09-08
Abstract: PURPOSE: To detect an edge pattern with facility by using a lighting step of a compact type and a good operating performance in such a manner that a ring-like light passage onto the edge pattern is partly shaded and light is radiated from the top onto a dark site, and the reflecting light is detected.  
     CONSTITUTION: A light emitted from a lamp 7 toward a rectilinear stepped pattern such as a circuit pattern 4 of an integrated circuit wafer, etc., is collected by a collector lens 8, only top and bottom portions 14 are allowed to pass by a light-shading slit 13 formed by being combined with a ring-like slit, the light is radiated though a ring-like mirror 10 and a ring-like condenser lens 11, and only an edge (solid line) 16 in the same direction as an arrow 15 is detected by irregular reflection using an object lens 12. And then,  an edge 17 directed perpendicularly to the other edge is detected either by turning the light-shading slit 13 by 90° or by replacing it with a slit in different direction. This irregular reflecting light is passed through the object lens 12 and formed into an image on a light-receiving surface of a image-projecting device and a position of the edge pattern is detected by characteristic point of the signal.

Abstract: PURPOSE:To cast stably an extra thick steel slab having a good surface shape without having a segregation band and compsn. defect on the surface at a high yield by blowing a gaseous refrigerant onto the surface of a molten steel cast into a casting mold to form a quickly cooled and solidified shell while allowing the molten steel to solidify from the base of the mold then adjusting the refrigerant to cool slowly the shell. CONSTITUTION:The molten steel 4 is poured into a molding board 1 and a molding flask 2 imposed thereon with a top cap 8 having vent holes 7 and is cooled to solidify from the board 1. On the other hand, an inert gas is blown from a supply pipe 5 to the top surface to cool quickly the top surface and to form the surface solidified shell.

Title: Scavenging control device
Inventor: IGUCHI HIRAYOSHI
IPC: F02B25/20
Filed: 1985-05-21
Abstract: PURPOSE:To eliminate an external power, by a method wherein a control valve, opening and closing a scavenging hole, is placed in the scavenging hole part of the cylinder liner of an internal combustion engine, the valve is coupled to a pneumatic driving device, and a power source, by means of which the device is driven, is automatically provided through the working of the engine. CONSTITUTION:During operation of an internal combustion engine, in the down stroke of a piston 33, the outer peripheral part of a valve liner 40 blocks an air passage hole 42 of a lower piston cover 41, and when a lower piston ring 45 is started to close a scavenging hole 32, air in air piston chamber 46 is compressed. When the piston 33 is lowered about to a bottom dead point, an air passage groove 43 is communicated with the air passage hole 42, and compressed air in the chamber 46 flows in a pneumatic cylinder 35. This causes depressing of the pneumatic piston 36 against a spring 37 to release the scavenging hole 32 by means of a scavenging control valve 4. Opening of the control valve 4 causes shifting of the piston 33 into a raising stroke, which is continued until the lower end of the valve liner 40 releases the air passage hole 42.

Filed: 1984-05-30
Abstract: PURPOSE:To prevent passivation of zinc to increase its reaction utilization factor by using a nickel supporting ring having an L-shaped cross section when a positive mix disk is placed in a positive can. CONSTITUTION:A positive mix 2 previously press formed into a disk plate shape is placed in a positive can 1 which also serves as a positive terminal and a nickel supporting ring 3 having an L-shaped cross section and a hardness of 80 in Vickers is arranged for reinforcing along the circumference of the positive mix disk 2. A separator 4 is placed on the mix disk 2, then a negative active material 5 is stacked thereon. A negative can 7 is placed through a gasket 6 inside the positive can 1, then they are sealed to form an alkaline battery. Since nickel is used as the supporting ring 3, passivation of zinc caused by chromium ion eluted in electrolyte is prevented. Therefore, reaction utilization factor is increased, and closed circuit voltage in heavy load at low temperature is increased.

After that, when addition water enters a container 21, the level of the water in the section 27 rises at the same ratio as that of the water in a treatment chamber 14 and at the same time air is evacuated through an aperture of the section 27.  On the other hand, the air on the surface of water in a section 26 is compressed and the increased pressure is detected by a pressure detector 23, an electric circuit 24 is driven, and water flow to the container 21 is shut. Moreover, at the time when water is discharged to sewage from the treatment chamber 14, water is made to inversely flow to the tank 17 through the entrance and exit.
