Title: Camera characteristics quantitating device
Inventor: KUWAJIMA NAOKI
IPC: H04N5/232
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To simply and surely quantitate camera characteristics such as focus and gain. SOLUTION: A CCD camera 3 photographs a prescribed area of a guide rail 2 at a prescribed position, of which a tape 1 in a relative color (white) to that of the guide rail is stuck, and the prescribed area includes borders between the tape and the guide rail. An image processing circuit 4 converts a photographed signal into digital data, which are given to an arithmetic circuit 5. The arithmetic circuit 5 obtains the sum of density of the image data in a X-direction, obtains a slant of the orders based on the sum of density and obtains a width W of the borders, based on the obtained slant of the borders and provides an output of the arithmetic processing.  When quantitating the characteristics, the operator adjusts a focus of the CCD camera 3 so as to obtain a relation of the border width W=1 so as to denote a matched focus, while viewing an image on a display screen based on the processing result from the arithmetic processing circuit. Thus, camera characteristics can be quantitated easily and surely without causing even slight deviations.

Title: Blanking die of helical gear
Inventor: MIZUTANI IWAO
IPC: B21D28/16
Filed: 1978-12-13
Abstract: PURPOSE: To shorten the manufacturing time of the helical gear and provide the press die which is readily adaptable even when the thickness of blank changes by using the helical gear blanking die for press of the same shape as the helical gear to be blanked.  
     CONSTITUTION: After an upper block 3 is lowered onto the plate-form blank B placed on a die 21, the bottom surface of a die cramp guide 9 is contacted to the top surface of a stopper block 28 and the descending of the guide 9 and block 3 is stopped. Next, the block 3 is further lowered from this state and a spacer 13 is force-crushed with a pressure holder 4, thence a backup plate 15 and punch 1 are simultaneously force-lowered. In addition, a plate 15 forces-down a plate retainer 8 by way of a needle bearing 16. Because of this, the plate retainer 8 with its helical teeth 8b being guided by the tooth grooves 9a of the guide 9 becomes integral with the punch 1 and lowers while rotating, thereby compression-bonding the blank M to the die 21 top surface. Next, the block 3 is further lowered from this state and at the same time the punch 1 is bitten into the blank M and is lowered while rotating until it blanks the blank M between the same and the die 21, whereby the helical gear W is produced.

IPC: H03K3/354
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To attain a stable circuit with less drift by taking the symmetry of each circuit into account thereby canceling fluctuation in characteristics with each other in the design of an integrated circuit. SOLUTION: When a free run frequency of a voltage controlled oscillator 104 changes, a voltage applied to a terminal 112 is changed automatically to keep an oscillating frequency of the circuit 104 to be a frequency fref of an oscillation circuit 107. When an optional voltage is given to a terminal 111 of a 2nd signal synthesis means 103, a voltage at a terminal 112 is adjusted so that the oscillating frequency of the circuit 104 is the fref . Thus, when the reference voltage at the terminal 112 is given to a 1st signal synthesis means 101, the oscillating frequency of the 1st voltage controlled oscillator 102 becomes fref by arranging characteristics of the means 101, 103 and the circuit 104.  When the frequency fref set to be a desired free run frequency fc and the voltage applied to the means 101 is the reference voltage, the oscillating frequency of the circuit 102 is fc and then the circuit for the free run frequency ffc is realized.

Abstract: PURPOSE:To prevent a breakage accident by contact between a nozzle and material by arranging a conductive detection plate at the position of material to be worked and detecting an electric current between a negative electrode rod and the detection plate to fix the distance between the bottleneck nozzle and the material to be worked. CONSTITUTION:At the time of confirming the distance between the bottleneck nozzle 3 and the material to be worked, when the conductive detection plate 8 is placed at the position of the material to be worked, the detected electric current I is allowed to flow to an electric current detector 9 through the detection plate 8. There is the established relation between said current I and the distance H between the nozzle 3 and the detection plate 8. Because of this, the electric current I is taken out via a filter circuit 10 and an amplifier circuit 11 and compared with a set value by a comparison circuit 12 and when a compared value exceeds a value, a signal is sent from the circuit 12 to an A/D conversion circuit 14 and the control is exercised via the circuit 14 so that the distance between the nozzle 3 and the detection plate 8 is fixed. As a result, the breakage accident by the contact between the nozzle 3 and the material can be prevented.

IPC: G11B21/08
Filed: 1988-06-23
Abstract: PURPOSE:To attain the smooth shift of an optical head without setting a drive point at the centroid position of the head by supporting the head with two parallel rigid body links having the same length and moving these links in parallel with each other and in an arc form. CONSTITUTION:Two parallel rigid body links 10 having the same length are set on two surfaces orthogonal to the feeding direction (arrow A) of an optical head 2. The tips of both links 10 are connected rotably via a coupling part 11 and the base ends 12 of both links are connected rotatably to the main body of an optical disk device via a rotary shaft part 12. In other words, the head 2 is supported by the links 10 at the centroid position of the head 2 so that the head 2 can move in parallel to the lengthwise direction of a linear motor yoke 6, i.e., toward the arrow A. When the driving force is applied to the head 2, the links 10 supporting the head 2 turn around the ends 12 respectively to move the head 2 in its feeding direction. In such a way, the head 2 is smoothly moved even though no coincidence is obtained between the centroid of the head 2 and a drive point.

Abstract: PURPOSE: To obtain a ceramic package base body which prevents a stress from being concentrated on a corner part and which prevents a crack from being generated by a method wherein the corner part at the inside stepped part of a pad, for a wire bonding operation, in a cavity as viewed from a plane is constituted of a curve and at least a part of the curve is situated at the outer side on the extension line of a linear side part at the inside stepped part of the pad. CONSTITUTION: In a ceramic package substrate for mounting a semiconductor element, a corner part 17a which is composed of a circle-shaped curve as viewed from a plane is formed at the inside stepped part 17 of a pad 16 for a wire bonding operation, and a part of the curve at the corner part 17a is situated at the outer side on the extension line of a side part 17d. In addition, the radius r2 of the curve constituting the corner part 17a is made larger than the radius r1 of a comparison example, and it is formed at the outer side from the corner part 20a. Thereby, a stress which is generated due to the difference in the coefficient of thermal expansion of a member due to an external force is hardly concentrated on the corner part 17a, and a crack is hardly generated in the corner part 17a. Consequently, the durability of the ceramic package substrate can be enhanced.

Abstract: PURPOSE:To reduce the frequency of the scattering of impurities of conductive carriers in a channel region and to restrain a drop in a mobility due to the scattering of the impurities of the conductive carriers by a method wherein one part of a single-crystal first-conductivity-type semiconductor substrate at a low impurity concentration is used as the surface of the channel region coming into contact with a gate insulating film. CONSTITUTION:N-type impurities are implanted deep into a P-type semiconductor substrate 1 by a high-energy ion implantation method; an N-type well 2 is formed. Part of the P-type semiconductor substrate 1 is left on the N-type well 2. The one part, of the P-type semiconductor substrate 1, which has been left on the N-type well 2 is used as a P-type channel region; a gate insulating film 4 and a gate electrode 5 are formed on its surface; and a source-drain region is formed. Since the impurity concentration of the P-type substrate 1 is low in this manner, the impurity concentration is low even in the P-type channel region using it. Consequently, a drop in a mobility due to the scattering of impurities of conductive carriers and the deterioration of the performance of a device itself due to it are not caused.
