Title: Template for sewing pattern
Inventor: KITAOKA HARUO
IPC: D05B39/00
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To use a template for sewing a pattern for different sizes in common, for parts having the same design, by providing a slide means holding a pattern so as to be relatively transferable along a pattern separating a set of first and second base plates from another set of first and second base plates. SOLUTION: The breadthwise distance between both side faces contacting the mutual end faces of the first auxiliary member 24M respectively is the differential distance of the No.9 pattern line from the No.7 pattern line for instance and the breadthwise distance of the second auxiliary member 24L is the differential distance of the No.11 pattern line from the No.7 pattern. Accordingly, the pattern line can be changed from No.7 to No.9 by only relatively transferring laterally the right lower base plate 11x and the left lower base plate 11y and positioning the first auxiliary member 24M in the space between mutual end faces of the right upper base plate 21x and the left upper base plate 21y.  And the pattern line can be easily changed for No.11 in an extremely short time by positioning the second auxiliary member 24L in the space between the mutual end faces of the right upper base plate 21x and the left upper base plate 21y.

Title: Device heat can be electrically turned off when toppled
Inventor: TSUKADA SHIGEAKI
IPC: F24C7/04
Filed: 1995-04-27
Abstract: PURPOSE: To surely hold the state where the feed to a heater is stopped when an equipment body upsets in an electric radiant heater to improve the safety. CONSTITUTION: This device has an upset off switch 11 connected in series between a heater and a power source, and the upset OFF switch 11 has a normally opened fixed contact plate 13 and a movable contact plate 14. A pressing body 21, a coil spring 27 and an earthing body 26 are provided to the movable contact plate 14. When an equipment body 1 is vertically placed on a surface 7 subjected to placing, the pressing body 21 pushes the movable contact plate 14 to bring it into contact with the fixed contact plate 13. When the equipment body 1 upsets, the movable contact plate 14 is separated from the fixed contact plate 13 by its own elasticity. A locking body 34 provided on the tip part of a leaf spring 33 is then engaged with the receiving recessed part 36 of the pressing body 21 to arrest the movement of the pressing body 21.  Thus, the pressing body 21 never movers even if a certain external force is added to the earthing body 26, and the upset OFF switch 11 surely keeps the OFF state.

Filed: 1987-04-30
Abstract: PURPOSE:To eliminate torque sensor and steering angle sensor in power steering device by carrying out switching of motor between driving and changing of rotary direction by means of turn right and turn left switches arranged on a steering wheel. CONSTITUTION:When a driver turns a steering wheel 1 to the left, a switch 2 arranged on the steering wheel 1 is turned ON. Consequently, a relay 12 functions to switch from connection between contacts 12, 14 to connection between contacts 13, 14. Consequently, current flows from a battery 11 through relays 10, 12 to a permanent magnet field motor 7 which produces rotary force for turning the steering wheel 1 to the left. Rotary force of the motor 7 is reduced through a reduction gear 6 and drives a steering device through a clutch means 5. When the steering wheel is turned to the right, the motor functions to turn the steering wheel to the right. Consequently, the driver can steer the wheel by placing his hand on the steering wheel and operating a switch.

Title: Serial connection circuit for self-arc-extinguishing semiconductor element
Inventor: HIGA OSAMU
IPC: H03K17/73
Filed: 1978-08-30
Abstract: PURPOSE:To eliminate the unbalance of the voltage applied to the semiconductor element and the switching loss by increasing the capacity of the capacitor connected in parallel for the self-arc-extinguishing semiconductor element featuring a short storage time and decreasing the capacity for the element featuring a long storage time respectively. CONSTITUTION:With addition of capacitor C30 with turn-off command (a) given to input terminal 11, gate turn-off thyristor GTO14 starts turn-off after storage time Tstg1. And the anode current flowing to GTO14 flows into diodes 17 plus C18 and 30. While storage time Tstg2 of GTO15 is longer then Tstg1 and with large amount of charge amount, but the anode voltage change of GTO14 is gentle since C30 is added. Then GTO15 starts turn-off after Tstg2 with the anode change more sudden (c) than GTO14. As a result, a balance can be secured between final value VA1 and VA2 for the anode voltage between GTO14 and 15 regardless of the different storage time.
