Title: Focus detector
Inventor: HAMADA MASATAKA
IPC: G03B3/00
Filed: 1985-10-12
Abstract: PURPOSE:To simplify arithmetic processing for range finding by using the absolute value of a difference between corresponding photodetecting elements between a reference part and a comparing part for the calculation of a relative function value to detect a shear from a focal position. CONSTITUTION:Outputs from respective picture elements in a CCD image sensor 20 are successively converted into digital signals D(X) by an A/D converter 24 and inputted to a four-picture element delay circuit 28 to delay four picture elements. A subtractor 30 calculates the difference DELTAD(X) between the raw picture element data and the data D(X+4) delayed by four picture elements and outputs the difference data DELTAD(X) successively. An absolute value calculating circuit 32 finds out the absolute value of the DELTAD(X). A defocus arithmetic circuit 42 calculates a defocusing amount (deviation) and a direction from an expected focus surface of a photographing lens 2 based on the difference data stored in a difference data storing circuit 40.

Title: Refill lead case
Inventor: SANO HIROMI
IPC: C08L101/16
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To ensure the dimensional stability over time and reduce a manufacturing cost by mixing at least a thermoplastic resin as a material for a refill lead case with starch, calcium oxide and an olive oil. SOLUTION: Starch, calcium oxide and an olive oil display a synergistic effect so that an antistatic and a biodegradable effect are generated more significantly. Therefore, the antistatic and the biodegradable promotion effect are imparted by adding the described ingredients to a common thermoplastic resin. Nevertheless, when the addition of the starch and the calcium oxide is less than 0.1 wt.%, both antistatic and biodegradable promotion effects become weak, so that it is desirable to add 1 wt.% or more starch and 0.1 wt.% or more calcium oxide. Although the antistatic and the biodegradable promotion effect are more significant in proportion to the increase of the addition weight, the dimensional stability becomes low when the loadings of the starch and the calcium oxide are 33 wt.% or more and 3 wt.% or more respectively.  The favorable loadings are less than the described weight percentages.

Filed: 1986-09-25
Abstract: PURPOSE:To improve the convenience in use by outputting a halt enable signal when a CPU detects a peripheral equipment replacing signal and bringing the CPU into the halt state and releasing the halt CPU by the output stop of the equipment replacement signal. CONSTITUTION:After the logic level of a line S4 is confirmed to be '0' through input ports B2,6, the level of an output register A2,1 goes from '0' to '1' to enable the halt to the CPU, since the logic level of the line S4 is already at '0', the CPU 1 goes immediately into the halt state through an AND circuit 2,3 and the line S2. Thus, the CPU 1 brought into the halt state and a character generator CGROM 5 is replaced. Moreover, the time when a 4-door switch is turned on till the CPU 1 reaches the halt state, is the time after a cover 4,1 is opened till the CGROM 5 is accessed. Thus, in replacing the CGROM 5 and closing the cover 4,1, the door switch 4 is turned off again, and the logic level of the line S4 goes to 1 from '0'. Then the level of the line S2 goes from '1' to '0' and the halt state of the CPU 1 is released.

Title: Electromagnetic fuel injection valve for internal combustion engine
Inventor: TAKAYANAGI HISASHI
IPC: F02M63/00
Filed: 1994-09-26
Abstract: PURPOSE: To facilitate the quantity regulating operation of fuel and to simplify assembling work by reducing a gap between the inner wall of a joint part hole of an injection valve and the outer peripheral wall of an adjusting pipe. CONSTITUTION: A fuel injection valve is opened and closed by separating a valve member from the valve seat of a valve body or bringing them into contact mutually. An electromagnetic actuator moves the valve member to an opening position against the energizing force of an elastic member when electric current is turned on. A level difference 71 to reduce a gap δ1 between the outer peripheral wall of an adjusting pipe 47 and the inner wall of the hole of a joint part 44 into a gap δ2 is formed in the outer peripheral wall of the adjusting pipe 47 which regulates the energizing force of the elastic member and moreover minutely regulates fuel injection quantity.  Since the fluctuation of the flow rate of leakage Q2 through the gap δ2 and the flow rate value of the flow rate of leakage Q2 are thereby lessened, the fine adjustment of the flow rate Q1 of the fuel becomes easy. Since the level difference 71 has an axial length not to damage the assembling ability of the adjusting pipe 47, the inserting assembling work of the adjusting pipe 47 into the hole of the joint part 44 becomes easy.

Abstract: PURPOSE:To attain proper picture processing to an n-value picture data by multiplying a constant number with a data of each picture element for an n- value picture so as to apply m-value processing and adding a correction value by gamma correction to the m-value processing data. CONSTITUTION:A binary color picture data is stored in a binary color picture data base 1 and an opening angle setting dot number integration section 2 is provided with a prescribed window including a noted picture element, number of 15 in the window are counted to obtain an average density. A correction arithmetic section 3 decides a correction value corresponding to the average density based on a gamma correction table and a constant number multiplier section 4 multiplies a constant number with a binary color picture data. For example, 255 is multiplied and the picture data is 0 or 255 and the data is expressed in 8-bit. An adder section 5 adds a correction value obtained by the correction arithmetic section 3 to a picture data obtained by the constant number multiplier section 4 and outputs the result to an output section 6. Thus, an n-value picture data is processed into an m-value processing (m>n) to apply proper picture processing.
