Title: Control circuit of hydraulic shovel
Inventor: SAKO YUKIO
IPC: E02F3/43
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To obtain the optimum closing speed of arm to correspond to the elevation and depression motion of the boom when directly excavating ground by a hydraulic shovel. SOLUTION: A control valve 14 for the pilot pressure is put in an arm-closing side pilot hydraulic oil passage 9 of a directional control valve 7 provided in the oil passage of an arm cylinder 1. The second oil passage 16 is branched from the boom-elevation side pilot hydraulic oil passage 13 of the directional control valve 11 provided in the oil passage of the boom cylinder 3 and a free piston 17 is interposed. When the closing motion of the arm and the elevating motion of the boom are simultaneously actuated, the piston 17a is moved to discharge the oil in the inside from the outlet and the control valve 14 is changed over to the position A connecting to a tank and the increase of the pilot pressure in the arm-closing side pilot oil passage 9 is suppressed.  When the movement of the piston 17a to the left side is weakened, the control valve 14 is changed over to the opening position B and the closing speed of the arm is increased.

IPC: B41J7/48
Filed: 1986-04-10
Abstract: PURPOSE:To obtain a small-type printer capable of secure operation and suitable for high-speed printing, by engaging two worm members selectively rotated and stopped through a controlling means with a gear rotated as one body with a type wheel. CONSTITUTION:First and second worms 30, 40 are engaged with a type wheel gear 12 on a carriage 10 to effect the rotation of a type wheel 13 for selecting a type, spacing of the carriage 10 and returning of the carriage 10 toward a home position, and are engaged with a paper-feeding gear 80 to effect paper feeding. A detecting gear 92 is engaged with the first worm 30, and is rotated synchronously with a timing gear 60 and the type wheel 12. After the rotation of a motor 50 is started, a detecting conductor 93b on the detecting gear 92 and a detecting brush 94b make contact with each other to generate a reset signal R, whereby the position of the type wheel 13 can be confirmed. After the confirmation of the position of type wheel 13, the conductor 93a for the detecting gear 92 makes contact with a detecting brush 94a, and the type wheel 13 is rotated until a timing signal T corresponding to a designated type 15 is generated. Accordingly, the position of the type wheel can be easily detected, and a controlling circuit can be greatly simplified.

Title: Continuous casting method
Inventor: KODAMA HIDEYO
IPC: B22D11/06
Filed: 1978-07-10
Abstract: PURPOSE:To enable cast ingots of sound quality free from any cracks to be stably obtained by providing draw-out pinch rollers of the specific speed at the time of continuous casting by moving casting molds consisting of a grooved rotary wheel  and a metal belt. CONSTITUTION:Molten metal 2 from a tundish 1 is poured into the moving casting molds having the space formed by a rotary wheel 3 provided with a casting groove on the outside circumference and an endless belt 4 given with tension by a pulley 5, thereby forming a frozen crust 6. Next, it is aligned and straightened by pinch rollers 7 whose revolving peripheral speed v is lower than the speed u of the moving casting molds constituted by the foregoing rotary wheel 3, etc., after which it is drawn to become a cast ingot 8. Although the frozen crust receives aligning and straightening under compressive force owing to the difference between the speeds u and v, it does not cause any frozen crust interface cracking. The production of cracks owing to tensile force at the freezing interface of conventional methods is obviated and the sound cast ingot 8 is obtained stably and continuously.

Title: Brushless motor control
Inventor: MORI TOMOYUKI
IPC: H02P6/182
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To conductor regular position detection and appropriate control without any interference with rotation control even in case of being unable to detect a position of a rotor in a brushless motor. SOLUTION: The voltage of an armature winding in a brushless motor 4 is compared with reference voltage by a position detection part 10 to obtain a position detection signal D. The signal D is inputted into a control circuit 11 to detect the position of a rotor in the motor 4, and based on the position detection, current-carrying of the winding voltage of the motor 4 is switched. At this point, the control circuit 11 counts time between position detection intervals. Based on the counted time, the time of the next position detection is predicted and position detection at the predicted time is checked. In case of no position, present current-carrying switching is conducted, based on that at the earlier time than previous switching time of current-carrying.  In case of no position, the control circuit 11 increases the input voltage low range for the motor 4 and increases the input voltage low range for every prescribed hour until position detection is obtained. The input voltage low range is limited according to frequency of an position detection, or this limit is released for position detection operation.

Title: Entrance and departure control system
Inventor: TANAKA TOMOYUKI
IPC: G06Q50/16
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent a user from forgetting to input the identification number by prompting a user to input the password if it is the time to input the identification number when identifying user information. SOLUTION: When a user passes an ID card through an ID card reader, a signal processing section 10 determines whether the ID card has been registered previously. If it is found to be a registered one, it is judged if it is the time to input the identification number. If it isn't the time to input the identification number, it is judged if the situation requires input of the identification number. If it is the time to input the identification number, the signal processing section 10 notifies a prescribed message with a display section 15 or a speaker SP, prompting the user to input the identification number. On this occasion, if the user instructs the postponement of input by a postponement instruction key 16A or a ten-key 16B, the signal processing section 10 registers the performance in a storage section 11 and prompts the input of the identification number at the next ID code identification time. At this time, the user is disabled from performing the postponement instruction operation, thereby preventing the user from forgetting to input the identification number.
