IPC: G06V30/164
Filed: 1981-11-04
Abstract: PURPOSE:To detect the scanning direction and the passage of a character, by inputting the link of black cells to a link detecting circuit for every column to discriminate the link logic and eliminating a black cell linked to no black cells as a dirt and cutting characters horizontally. CONSTITUTION:The control of nXm-number of cells of a sensor 6 and the binary output from a binary circuit 7 are inputted to a link detecting circuit 16, and the output of the circuit 16 is outputted to a horizontal cutting circuit 10 and a scanning direction detecting circuit 14. The circuit 16 detects a dirt on a basis of the white or black state of cells adjacent to a black cell and discriminates the dirt in 2X2 partial matrixes successively when the one-bit dirt should be removed. Thus, even if the dirt exists in the space between characters, the dirt is eliminated.

Title: Pachinko game machine
Inventor: SATO SHOJI
IPC: A63F7/02
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To easily adjust a position for shooting game balls to a game board, regarding a pachinko game machine. SOLUTION: When a player touches an operation handle 18, game balls fed from an upper tray 14 are shot with a shooting device one after another. The player turns the operation handle 18 and adjusts the yawing angle of a discharge nozzle 26, looking, for example, at the locus or the like of the game balls shot to a game board 12 from the discharge nozzle 26, thereby shooting the game balls to a desired position. In this case, the game balls can be discharged to a desired position on the upper part of the game board 12 by turning the operation handle 18 and adjusting the yawing angle of the discharge nozzle. Thus, the game balls can be more easily discharged to a desired position on the game board 12 than in the case of the adjustment of the strength of a shooting force.

Title: Dielectric porcelain composition
Inventor: HASHIGUCHI TAKAO
IPC: H01G4/12
Filed: 1994-07-28
Abstract: PURPOSE:To provide a dielectric porcelain composition having a high dielectric constant, with the dielectric constant not greatly dependent on temperatures so that the rate of decrease in capacity value is reduced, by preparing in a specific ratio a solid solution consisting of BaTiO3, CaZrO3 and CaTiO3, and Nd2O3 which serves as an additive. CONSTITUTION:Thus dielectric porcelain composition comprises a composition of formula-l type whose constituents are in a ratio indicated by formula II, with 0.010 to 0.016wt.% Nd2O3 added to the constituents. When (x)+(y)+(z)=1.0, the values of (x), (y) and (z) are 0.890<=(x)<=0.910, 0.070<=(y)<=0.095, and 0.010<=(z)<=0.025. When the amount of Nd2O3 added is less than 0.010wt.% of solid solution constituents, sintering of porcelain tends to become difficult whereas if the amount of Nd2O3 added is greater than 0.016wt.%, dielectric losses tend to become great. The dielectric porcelain composition can provide dielectric porcelain having a great porcelain density and good porcelain strength. Therefore, a stacked ceramic capacitor excellent in a temperature characteristic during use can be provided.

IPC: D05B47/04
Filed: 1987-07-15
Abstract: PURPOSE: To collect the correct cloth thickness of a place where seams are actually formed, to correctly calculate a required thread quantity corresponding to the cloth thickness and to form the excellent seams by detecting a work cloth by means of the contact resistance of the work cloth, which is worked on a needle. CONSTITUTION: A work cloth detecting means 14 detects the work cloth based on the contact resistance of the work cloth, which is worked on the needle, by the downward movement of the needle which is vertically moved through the work cloth on a work cloth support surface. A cloth thickness arithmetic means 42 calculates the thickness of the work cloth by a timing for detecting the cloth work by the means 14 and a timing when the needle comes to a prescribed position in the vertical movement locus of the needle, that is, the timing when it arrives at an upper dead center. Therefore, correct cloth thickness data of a needle fall point position, that is, the places where the seams are actually formed are collected regardless of a cloth feeding direction.  Then, a correct upper thread quantity corresponding to the cloth thickness is calculated and fed so that the excellent seams are formed.

IPC: B23P19/00
Filed: 1985-08-13
Abstract: PURPOSE:To make robot operations adequate to a work by controlling robot operation axes in response to the presence/absence and type of the work based on parameters selected from operation parameters stored based on a work judging means. CONSTITUTION:An arithmetic unit 4a is fed with a work detection signal from a work detector S and judges the presence/absence of a work, and selects a parameter I if the work is present and selects a parameter II if the work is absent, and sends the selected parameter I or II to a servo drive unit 6a. The servo drive unit 6a drives each servo motor of operation axes R based on the parameter I or II sent from the arithmetic unit 4a. Thereby, individual operation axes R are controlled with the predetermined operation speed, acceleration rate, and position loop gain to perform adequate operations in response to the presence or absence of the work W. Accordingly, the work detector S is provided at the hand tip of a robot 1, and operations are changed by actually detecting the work W, thus operations when the work is absent can be performed at a high speed and efficiency can be improved.
