IPC: H03M11/04
Filed: 1991-04-26
Abstract: PURPOSE:To improve the operability of keys of a keyboard device by inputting a command to each of plural keys to temporarily change the arranging form of functions corresponding to those keys respectively and informing the set arranging form of keys to an outside. CONSTITUTION:A pointing means 11 inputs a command to temporarily change or cancel the arranging form of functions corresponding to plural keys having different functions. A temporary storing means 12 sets the arranging form of functions as instructed by the means 11 and holds this arranging form. A reporting means 13 informs the arranging form of function set by the means 12 to the outside by a display element 7 through a semitransparent window of a conversion key, etc. That is, when a certain key is frequently used, an operator converts temporarily the function forms of other keys set the easy-to- handle positions into the function form of the key used frequently. Thus these converted keys are temporarily used as the keys which are frequently used. This fact is informed to the outside.

Abstract: PURPOSE:To read colors, etc., in various ways by sharing 1st and 2nd mirrors set in parallel with each other and providing plural pairs of image forming lenses and photoelectric transducers at the different positions in the longitudinal direction of a slit-shaped original image. CONSTITUTION:The three pairs of CCD 42 and image forming lenses 43 are provided at different positions in the longitudinal direction of the slit-shaped original image together to share the 1st and 2nd mirrors 28d and 38. While a CCD 42G is set on the center line in the transverse direction of an original 23 with CCD 42R and 42B set at positions out of the center respectively. These CCD have the same distance from the surface of the original 23 and therefore the color component pictures are projected and formed to each CCD with the same magnification. Thus the color separated images are formed to those CCD 42R, 42G and 42B respectively based on the luminous fluxes 41R, 41G and 41B which are reflected with folding between both mirrors 28d and 38 even with color originals. Thus the colors can be read in various ways.

Title: Measuring device of air current
Inventor: SUGIHARA YOSHIBUMI
IPC: G01P13/00
Filed: 1993-04-28
Abstract: PURPOSE:To measure accurately the direction and velocity of a steady-state air current generated at a platform or others of a subway, separately from a train wind. CONSTITUTION:A pair of L-shaped total pressure tubes 10 and 12 are provided at a prescribed position of a subway platform 14. The total pressure tube 10 is disposed with its total pressure measuring hole 10A directed onto the negative air direction side, while the total pressure tube 12 is disposed with its total pressure measuring hole 12a directed onto the positive air direction side, and the total pressure of an air current flowing in the positive direction is detected by the total pressure tube 10, while the total pressure of an air current flowing in the negative direction is detected by the total pressure tube 12. A differential pressure gage 20 computes a difference DELTAP between the total pressures in the positive and negative directions of the air currents detected by the total pressure tubes 10 and 12, converts this difference DELTAP between the total pressures into a voltage value V and outputs it to an arithmetic unit 24. The arithmetic unit 24 integrates the voltage value V by a prescribed detecting time T and determines quantities of air in the positive and negative directions. Then, the arithmetic unit 24 subtracts the quantity of the air in the negative direction from that of the air in the positive direction, divides the quantity of the air determined by the subtraction by the detecting time and thereby determines the direction and velocity of a steady-state air current V0 flowing through the subway passage 14.

Title: Prize winning device for pachinko machine
Inventor: KIMURA HARUMICHI
IPC: A63F7/02
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a pachinko machine in which pachinko balls are not clogged even when two balls win a prize. SOLUTION: A pair of opening/closing members 40a and 40b are formed so that the pachinko ball guide surface 44b of one member 40b constitutes a steep slope when the guide surface 44a of the other member 40a constitutes a gentle slope in the case of an inclination state. Then the guide surfaces 44a and 44b of a pair of members 40a and 40b are asymmetric in the inclination state so that the ball falling along one steep slope surface 44b goes down at higher speed than that falling along the other gentle slope surface 44a. Therefore, a situation where two balls are simultaneously held between a pair of opening/closing members 40a and 40b hardly occurs even when the two balls from left and right parts simultaneously win the prize, and ball clogging is suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for describing a shape model with a feature point such as a welding point or the like as the center and accurately executing the recognition processing of the position of the welding point or the like corresponding to the description. SOLUTION: With the welding point Q as the center, division into the left side profile and the right side profile is performed and the shape model is described.

For the left profile, the line segment A is extracted first and the line segment B is extracted while utilizing the information. Also, for the right profile, the line segment D is extracted first and the line segment C is extracted while utilizing the information. In such a manner, since the line segments B and C are both accurately obtained since the line segments A and D are relatively long and thus accurately obtained, the welding point Q, which is their intersection, is also accurately obtained.
