Title: Head switching mechanism of auto reverse tape recorder
Inventor: OSANAI HIROSHI
IPC: G11B5/54
Filed: 1981-05-12
Abstract: PURPOSE:To switch heads rapidly and securely with simple constitution by controlling the rotation of a head lever in engagement with a solenoid plunger. CONSTITUTION:When the plunger of a solenoid 16 moves inward, a diamond- shaped piece 72 moves in one body to move a guide pin 80 along a groove 85, turning an operating plate 82 counterclockwise. When the pin 88 of this operating plate 82 passes through a neutral point, the operating plate 82 turns counterclockwise instantaneously by a torsion spring 92, and a head lever 12 mounting heads 22 and 23 rotates clockwise around a shaft 18 by coupling with the plunger. Similarly, the lever 12 rotates counterclockwise by coupling with the drawing-out operation of the solenoid plunger, so that switching of the heads to the neutral position or to the touch position of a forward or reverse running tape is performed smoothly, rapidly and securely by the constitution, which eliminates the need for a slide lever, in direct engagement with plunger motion.

Abstract: PURPOSE:To execute KANJI (Chinese character) input by KATAKANA (Japanese syllabary) character by having the function to convert to the KANJI when KATAKANA character is inputted to an optical character recognizing device in accordance with a certain rule. CONSTITUTION:A scanning means 2 scans an original picture 1, cuts out the pattern for respective characters and outputs to a recognizing means 4. The recognizing means 4 recognizes the character pattern inputted from a scanning means, decides whether or not said character is the one for which the KATAKANA KANJI converting is required on the slip, and stores the information and a character code obtained as the result into a memory means 4. A control means 5 displays a character image corresponding to the character code in the memory means 4 at a displaying means 8, extracts the KANJI character code of the candidate character corresponding in a dictionary means 6 for the character column 'easily' for which KATAKANA/KANJI converting is required on the slip, and displays the corresponding character image. An operator confirms the character, and when the error does not exist at the display, gives the indication of the confirmation completion through a key input means 7 to the control means.

Title: Combustion apparatus for pressurized fluidized bed
Inventor: NISHIYAMA AKIO
IPC: F23C10/16
Filed: 1994-04-11
Abstract: PURPOSE:To provide a combustion apparatus for a pressurized fluidized bed, capable of cooling medium transport pipes by means of a simple system without using hot water. CONSTITUTION:Medium transport pipes (supply pipe 10 and extraction pipe 11) for transporting a medium between a furnace 4 of a pressurized fluidized bed boiler and a medium storage tank 9 have a double pipe structure provided, on the outside of the medium transport pipes, with pipes 18, 19 for allowing air to pass therethrough, and the medium transport pipes 10, 11 are always cooled by air in the double pipes. Due to this air cooling, an increase in temperatures of the medium transport pipes 10, 11 is small even in the case where the medium is transported at the time of variations in a load, and the medium transport pipes 10, 11 are neither extended nor contracted by temperature fluctuations which are caused at the time of variations in a load and operation under a fixed load, whereby the thermal deformation and breakage of the pipes can be prevented. Since air for cooling the medium transport pipes recovers a heat quantity retained by the medium, it is desirable that combustion air for fuel for the pressurized fluidized bed boiler is used as cooling air by partially branching, and the efficiency of a plant can also be improved by returning that air into the furnace 4.

Title: Subframe mount device in vehicle
Inventor: MINAGAWA MASAAKI
IPC: B62D7/20
Filed: 1985-04-05
Abstract: PURPOSE:To prevent the steered angle of the front wheels from varying due to the rolling of a subframe, by decreasing the rigidity of a mount member in the direction orthogonal to the plane including therein the center of a lower arm support bushing and the axis of the tie-rod. CONSTITUTION:The rigidity of mount members 7, 8 for supporting a subframe 9 to a vehicle body frame 6 is decreased in such a direction that they are allowed to be displaced in only one direction along the axes 20, 23 orhogonal to the plane 12 including therein the center of a bushing 10 and the axis of a tie-rod 5. With this arrangement, when a force causing the rolling of the subframe 9 to occure is applied, the mount members 7, 8 inhibit the subframe 9 from being displaced in the vertical direction, but allows it to be displaced along the axes 20, 23. Accordingly, the subframe 9 is displaced in only one direction orthogonal to the plane 12, and therefore, the longitudinal relative movement of the lower arm 3 and the tie-rod 9 never occures, thereby it possible to prevent the steered angle from varying.
