Filed: 1994-06-17
Abstract: PURPOSE:To eliminate an undesirable bad effect or an ache in the heel by way of the upper surface of a sole sinking in an inside portion of a ring-formed plate portion of shank when a heel gets on a shoe sole, the heel keeping the shape of a natural roundness so that it fits to the upper surface of a shoe sole. CONSTITUTION:A shank 3 is formed of elastic steel plate, and has a narrow width plate portion 1 in the front half and a ring-formed plate portion 2, the middle of its roughly elliptic plate being lowered, in the rear half, and bends delicately conforming to the shape of the rear of a foot. The narrow width plate portion 1 lowers somewhat in its front and slightly inclines toward the upper face, and the ring-formed plate portion 2 slightly inclines in upper surface so that the central portion lowers, i.e., the inner portion is lower than the outer portion. A bead (groove) 4 in longitudinal direction is disposed on upper surface of the narrow width plate portion 1 and also a bead 5 is disposed on lower surface of the ring-formed plate portion 2 along periphery of a hole, in order to increase the strength.

Title: Miniaturized motor
Inventor: MATSUDA SHINICHI
IPC: H02K3/34
Filed: 1985-07-19
Abstract: PURPOSE:To prevent the undesirable spring back produced at the bent-up portion of an insulating core by composing the insulation core of metal foils clad inside the resin films. CONSTITUTION:An insulating core 1 is formed by bending up the bent-up portion 2 corresponding to the winding portion of the rotor winding at each pole. Here, the resin films 3 are clad with the metal foils 4 and laminated. Thus the undesirable opening to outside, i.e., the spring back 6 formerly produced in the insulating core, which has so far been formed of resin films only, is no more produced with the support of the plasticity of the metal foils 4.

Title: Absorption heat pump
Inventor: FURUKAWA TETSUO
IPC: B01D3/32
Filed: 1985-07-18
Abstract: PURPOSE:To prevent elevation of boiling point due to rise of pressure by the depth of liquid of an absorption heat pump by boiling bottom liquid of a distillation tower by feeding the liquid from an upper part of tubes of an absorption tower as downstream, and providing a duct for returning the liquid to the bottom of the distillation tower. CONSTITUTION:Water 2 fed to an evaporator 1 is heated and evaporated by the vapor 5 from the top of a distillation tower 4 flowing through a heating pipe 3 and transformed to steam. The steam is fed to an absorber 6 and absorbed by LiBr-H2O soln. 7, liberating thereby condensed liquid. On one hand, bottom liquid 8 of the distillation tower 4 is fed to the upper part of the heating pipe 10 provided perpendicularly in an absorber 6 through a circulation pump 9, then flows downward in the heating pipe 10 and heated to boiling by the heat of condensation of the steam from the evaporator 1 forming gas/liquid two phase flow 11, and fed back to near the bottom 12 of the distillation tower 4. Accordingly, the tower bottom liquid 8 flows through the heating pipe 10 as downflow liquid, thus, elevation of boiling point due to pressure rise is prevented.

IPC: G11B20/12
Filed: 1983-09-02
Abstract: PURPOSE:To improve the transfer efficiency of data by dividing the write data connected logically into each block throughout each truck is set track and recording these divided data for each of paired tracks simultaneously and independently every block physically to eliminate the idle time of a transfer block when viewed from a host device. CONSTITUTION:The data on a channel 16 of a host device 15 is transferred directly to an external memory 17 and also indirectly after the temporary storage to a buffer memory 19 incorporated to the memory 17. The memory 17 forms a paired track 13 from tracks A and B and records the even blocks to the track A and the odd blocks to the track B respectively in terms of a block number 12. In case the data is written from an even number block, a record order switch 20 is set at the write side W with a transfer system switch 18 set at the indirect transfer side (i) to store temporarily the data of number ''0'' to the memory 19. Then the switch 18 is changed to the direct side D to write the data of No.''1'' to the track B. At the same time, the data of number ''0'' of the memory 19 is written to the track A. Thus the idle time of a transfer block can be eliminated when viewed from the device 15.

Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a correcting method of a plasma display panel when barrier ribs thereof are of a white color or a bright color close thereto. SOLUTION: According to this method, a defective part caused by clogging or thickening of barrier ribs 8 on a back plate of a plasma display panel is corrected by the use of a laser beam. In cases where the barrier ribs are of a white color or a bright color close thereto, their shapes are first corrected by removing the defective part by a laser beam of high output and then corrected by removing discolored parts around the corrected portion by a laser beam of low output. In cases where the defective part is a cutoff part, it is repaired by coating or filling it with a barrier-rib material and then the repaired portion can be corrected in the same manner.

Title: Time setter for equipment
Inventor: ZAIZEN KATSUNORI
IPC: G04G5/00
Filed: 1985-07-19
Abstract: PURPOSE:To elevate the operability of the equipment, by selecting either of the time memorized by a memory means and the time counted by a time counting means for counting time according to the input of a time input means. CONSTITUTION:When a time setting key 10 is inputted, a memory means 3 receives the input of a time signal being counted to memorize. The time memorized is applied to a display means 5 through a time selection means 4 to be displayed. So, the display remain unchanged regardless of any change in the time being counted by a time counting means 1. Then, with the inputting of the hour key 11, the minute digit is advanced accordingly in the minute digit to be displayed. When the time setting key 10 is inputted after the time in the memory is set to a desired time with the hour key 11 and the minute key 12, the time memorized in the memory means 3 is displayed by a display means 5 through a time selection means 4 to complete the setting operation. This enables the time counting means 1 to continue the time counting operation even during the setting operation without affecting the display time thereby elevating the operability of the equipment.

Title: Transparent flat switch
Inventor: YAKIDA KIYOSHI
IPC: H01H13/70
Filed: 1989-06-26
Abstract: PURPOSE:To prevent a movable electrode from being brought into contact with a stationary electrode under a non-pressurized condition even if first and second insulative sheets are made of materials different from each other by forming an insulative layer made of a transparent material having a heat expansion coefficient lower than that of the first insulative sheet. CONSTITUTION:An insulative layer 21 is made of, for example, a glass material having a heat expansion coefficient lower than that of a first insulative sheet 1. Upon rising-up of a temperature, a displacing force P1 to approach a stationary electrode 7 is applied to a movable electrode sheet 5 due to the expansion of the first insulative sheet 1. The movable electrode sheet 5 is, however, covered with the insulative layer 21 having the heat expansion coefficient lower than that of the movable electrode sheet 5 so that a force P2 for restraining deformation due to the expansion of the first insulative sheet 1 is exerted simultaneously. With this restraining force P2, a movable electrode 2 can be prevented from being brought into contact with the stationary electrode 7 under a non-pressurized condition.
