Abstract: PROBLEM TO BE SOLVED: To realize an operation with the maximum efficiency by forming a PWM pulse from a modulation output voltage command value obtained by superimposing a sine wave AC signal to an output voltage command value to realize PWM control for an inverter and by minimizing an input current of a motor to control an output voltage of the inverter. SOLUTION: At the time of starting and accelerating a motor 4, acceleration gradient output frequency command value generated by an acceleration setting unit 7b is added to a PWM inverter control circuit 5 and also to a voltage deciding circuit 8 to gradually increase an output voltage command value Vin and output frequency command value for the acceleration control. When the number of rotation reaches the target value, the changeover switches 10, 11 are operated by a changeover switch control circuit 12, control by a minimum current following control circuit 9 starts, the sine wave is superimposed to an output voltage command value Vin to form a modulation output voltage command value Vout to minimize a primary current I1 of the motor 4 for a load torque. Thereby, the motor 4 can be operated in the maximum efficiency.

Title: Printer
Inventor: KIKUCHI KO
IPC: B41J11/42
Filed: 1988-10-21
Abstract: PURPOSE:To effectively and easily detect the position of a perforations by providing a slit at a lead spring of a printing medium retainer provided on the passage of a printing medium, and enlarging the variation of sheet thickness to monitor it by a noncontact type sensor. CONSTITUTION:At least one slit 13 arriving at the vicinity of a presser 12 from a stationary unit 11 is formed at a leaf spring 6 for pressing a printing medium on a platen 2. One of a plurality of pieces with the slits 13 is released from the unit 11 to become a free piece 14. As the spring 6 is deformed, the piece 14 can be freely moved. When a perforation is abutted against the presser 12, the sheet thickness is increased only at the part of the perforation. Thus, the presser 13 is vibrated for a short period of time. In this case, since the end 15 of the piece 14 amplifies the vibration of the presser 12 to be moved, its displacement can be easily detected by a displacement sensor 7.

Title: Cushioning material for concrete product
Inventor: HORAI KAZUHIRO
IPC: E03F5/04
Filed: 1994-10-27
Abstract: PURPOSE: To stably hold a cushioning material in a form during concrete forming and to prevent a locking projection embedded in a product from cracking and rupturing after construction by integrally joining together a form- attracting portion made of a magnetoelastic material and a locking portion made of a non-magnetoelastic material. CONSTITUTION: A form-attracting portion 31 formed of a magnetoelastic material and a locking portion 32 formed of a non-magnetoelastic material provided inside concrete are integrally joined together. A hook-shaped locking projection 33 is provided integrally with the center of the plane of the locking portion 32 to form a cushioning material 30. The cushioning material 30 is attached to time step 11 of a side-groove block 10. During concrete placing, the cushioning material 30 is attracted to a form by the magnetic force and is therefore not moved even by pressure produced by the pouring of concrete. Therefore, the cushioning material 30 absorbs the wobble of a concrete product even after construction to prevent noises and impacts, and is made lightweight for easy handling and transportation, and the material and manufacturing costs can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a game machine which has novel game contents and high contrivances and enables a game player to play with interest any time. SOLUTION: A pinball game machine 1 is made such that when a game ball got in an ordinary variable premium port 4, a figure displayed on a special figure display section 3 changes and becomes a fixed display after a predetermined time, and when the figure displayed as fixed is a 'prime winning fighre', the 'prime winning state' occurs. And, when the displayed 'prime winning figure' is a 'specified prime winning figure', the 'high probability state' occurs after the 'prime winning state' finishes.  Furthermore, in certain case out of the cases when the 'prime winning figure' is displayed as fixed an 'unspecified prime winning figure' is displayed as an once stop before the fixed display, and after the once stop display the expectation level on which the 'specified prime winning figure' is displayed as fixed is displayed on the specified figure display section 3 as the 'specified expectation level index'.

Title: Step motor
Inventor: OKAMURA YUKIHIKO
IPC: H02K11/00
Filed: 1985-11-25
Abstract: PURPOSE:To prevent the burnout and short circuit arising from the overheat of coil by detecting the temperature of the coil with a thermocouple contacted with the coat of the coil. CONSTITUTION:A coil 4 is formed so that a thermocouple 5 can contact with the coat of the coil 4. The temperature of the coat of the coil is detected with the thermocouple 5 as the voltage signal, by means of which the coil current is regulated. That is, when the coil 4 is overheated and the thermocouple 5 gets to a certain voltage, e.g. the voltage value at the maximum temperature of the coat of the coil 4, a signal is given from a comparator 6 to a switch 7, which is then turned off to break the current to a driver 2, stopping a step motor 3. Thus, even if the step motor is driven by misoperation, etc. in other than the normal condition, the burnout and the short circuit of the coil can be prevented.

Filed: 1991-10-14
Abstract: PURPOSE:To decrease a shaft shake of a hub by fixing a spindle output shaft integrated with the hub to a housing via respective ball bearings and supplying two spindle output shafts themselves at the edge parts. CONSTITUTION:The hubs 1a, 1b are integrated into one body with the hub and the spindle output shaft and are connected by interposing one steel ball 8 in a middle of two ball bearings 7a, 7b. The rotational force generated with a rotor 4 is transferred to the hum 1a, the ball bearings 7a to rotate them smoothly. At this time, in order to impart a rotation synchronized to the hub 1b, the ball bearings 7b, the hubs are fastened by interposing the steel ball 8. The hubs are formed at a nearly same length being divided into halves, so the shaft shake is less than the shaft on the other side and the workability becomes better, since the hub is formed by being integrally molded.

CONSTITUTION:The space heater is equipped with a suction filter 6 having a plurality of protrusions 8c, 8d, 8e at both right and left ends of the suction filter and side plates 16 having substantially quadrant-shaped slide rails 16a supporting the above-mentioned protrusions slidably at both right and left ends of the suction filter, and consists of a suction filter netting 7 and a resinous frame 8 formed integrally with the netting, the resinous frame being provided with grooves 8a, 8b in a vertical direction against the direction in which the suction filter slides, and the thickness of the resinous frame 8 at the portion of the grooves being made substantially equal to the thickness of the netting. According to this constitution, when the suction filter 6 is inserted into the insertion port 15 of a hot-air heater body 9, the suction filter 6 is bent into a quadrant shape along the slide rails 16a of the side plates 16 by applying the grooves 8a, 8b as hinges and is set in the slide rails. Therefore, the area of the suction filter 6 can be made fairly larger than that of the suction port 14, and even in a case where the suction port 14 is small, the frequency of cleaning the suction filter 6 can be reduced.
