Abstract: PURPOSE: To torus electrode is provided near the upstream end of the narrowed cylindrical path, a needle electrode is provided concentrically to the torus electrode, a wide cylindrical path is connected with the upstream end of the narrowed path, and a voltage is applied to these electrodes, thus giving efficiently electric charge to a powder.  
     CONSTITUTION: Torus electrode 3 is provided near the upstream part in narrowed cylindrical path 6 and a needle electrode 2 is equipped concentrically to the torus electrode. Further wide cylindrical path 4 is connected to the upstream end of the narrowed path 6. Then a direct current voltage is applied between the needle electrode 2 and the torus electrode 3 using conductive wires 12 and 13. The wide cylindrical path 4 makes the mix stream of fluid and powder extremely swift at the part remarkably near the surface of the torus electrode 3, thereby preventing the fine powder particles from fusing and accumulating on the surface of the torus electrode 3 efficiently for long periods of time.

Title: Playing machine having lottery function
Inventor: TAKEMOTO TAKATOSHI
IPC: A63F7/02
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To continue the interest to the play by making a control that the next lottery result becomes the quasi-big prize or the regular big prize when the corresponding display pattern is the specified one if the quasi-big prize is given by the lottery to further increase the expectation for the big prize and to reduce the uneasiness of continuous blanks. SOLUTION: When a pachinko ball shot on a play board surface enters each prize port, the prize balls of the prescribed number are delivered. When the ball enters a starting prize port 13 of the prize ports, a prize detection switch 14 detects the ball, and the prize signal is transmitted to a CPU 61 of a play control part 50b of a controlling means 50. The CPU 61 then starts the execution of the lottery. In the lottery, the quasi-big prize, the big prize, and the blank are judged. When the CPU 61 makes the control that the result of the lottery is either the quasi-big prize or the big prize when the control means is started if the selected display pattern for the quasi-big prize is the predetermined specified pattern in a case where the lottery result is in the quasi-big prize condition.

Title: Hydraulic control unit for lubricating circuit of interal combustion engine
Inventor: OTA HISAYOSHI
IPC: F01M1/20
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent insufficient lubrication to the part of the sliding portion owing to the fact that the suction speed of the lubricant is higher than the supply speed through the pump, thereby leading to the lubricant being sucked. SOLUTION: When controlling a hydraulic drive unit 1 under no hydraulic pressure in the forward direction thereof using a rotational force, the resistance to a hydraulic drive oil passage 40 is increased. When controlling the hydraulic drive unit 1 in the opposite direction, the resistance to the hydraulic drive oil passage 40 is decreased. This makes it possible to prevent insufficient lubrication to the part to be lubricated owing to the lubricant sucked by the hydraulic drive oil passage 40 when the hydraulic drive unit 1 moves toward the stable control position at a low hydraulic pressure.

Title: Anti-theft device for vehicle
Inventor: USAMI MAMORU
IPC: B60R25/10
Filed: 1980-04-24
Abstract: PURPOSE: To prevent the driver from uncomfortable feeling and neighbors from trouble, by such means that sounds of low and high levels are successively generated from a device unless an ignition switch is turned on within a certain time after the opening of a door and the sounding is ceased if the above described switch is turned on.  
     CONSTITUTION: Even if a key is removed to turn off an ignition switch, a timer 7 stores in memory insertion of the key for a certain time, and if a door is opened, a timer 8 operates to store in memory the opening of the door for a certain time. For normal use, since a short length of time is required for the driver to remove the key, open the door and to get off to the outside, an AND circuit 9 generates no output. If the key is removed to open the door with the lapse of certain time, the timers 7, 8 generate outputs, then the AND circuit 9 generates output to operate a display device 13 through a chain circuit 10 and oscillator 12 thus operate a relay contact 15 and horn 2. Through these operations are stopped if turned on a switch 5, a chain timer 11 operates to close the contact 15 causing the horn 2 to sound in a higher level unless the switch is turned on.

Title: Recognition candidate analyzing method and device therefor
IPC: G10L15/06
Filed: 1992-03-16
Abstract: PURPOSE:To avoid the decision invalidating state of a final recognized result, and to reduce an erroneous recognition by changing a threshold value set at present when one or both of the threshold value and the recognized result is suited to a preliminarily set condition. CONSTITUTION:A threshold value changing part 11 sets the threshold value according to user information, and changes the threshold value when one or both of the threshold value and the recognized result of a recognition candidate is suited to the preliminarily set condition. That is, at the time of receiving a signal indicating that the recognition candidate is not the final recognized result from a threshold value comparing part 12, the threshold value changing part 11 sets the second threshold value, searches a difference between the recognition evaluation point of the recognition candidate whose recognition evaluation point is the highest in a recognition candidate group, and the recognition evaluation point of each other recognition candidate, and changes the second threshold value to the value smaller than the value set at present from the next analysis when the other recognition candidate whose pertinent difference is smaller than the second threshold value is present. And also, the threshold value comparing part 12 compares the recognition evaluation point of the recognition candidate with the threshold value set by the threshold value changing part 11, and outputs the signal indicating whether or not the recognized result is appropriate.

Title: Transistor amplifier
Inventor: YOSHIDA YOSHIHIRO
IPC: H03F3/45
Filed: 1983-03-31
Abstract: PURPOSE:To obtain a differential output amplifier having the capacity for operating at a low voltage and a broad dynamic range by connecting emitters of output transistors (TRs) of two sets of current mirror circuits by a resistor and connecting an input of the one circuit to a bias means. CONSTITUTION:When an input signal DELTAIIN from an input terminal IN is larger, a current flowing to a TRQ13 and a resistor R14 is large, a base potential of one output TRQ11 is increased and one output current Iout1 is increased. Although the potential at an emitter terminal 11 is increased, since the base potential of the other output TRQ12 is constant, the potential at an emitter terminal 12 is kept constant and the other output current Iout2 has a decrease by the share corresponding to the increase in the current flowing from the emitter terminal 11 via a resistor 11, thereby obtaining a differential output. Only one stage of the TR exists between the power supply lines, then the low voltage operation is attained and a low distortion factor is attained by setting the voltage drop of the emitter resistor larger than the fluctuating component of the potential between the base and emitter.
