Title: Movable blade type compressor
Inventor: HAYASE ISAO
IPC: F04C18/344
Filed: 1980-08-01
Abstract: PURPOSE: To lessen fluctuation of drive torque by forming a sectional curve line representing the inner wall of a cam ring with a nonsymmerical shape and by shifting the most radially expanded portion to the air suction nozzle side.  
     CONSTITUTION: A sectional curve line representing the inside wall of a cam ring 38 is formed into a nonsymmetrical shape, and the most expanded portion of the cam ring 38 is shifted the air suction nozzle side. With this construction, when the air having the same volume is compressed to the same discharge pressure, work can be done over a large angle of revolution of a drive shaft. Therefore, the drive torque is made flat, thereby lessening flactuation of the drive torque.

Filed: 1994-05-19
Abstract: PURPOSE:To rapidly cool a room by conducting the concentrating operation of absorbing solution at a suitable timing. CONSTITUTION:A controller 30 has first calculating means 7 for calculating the changing speed of an indoor temperature from an indoor temperature measured by a sensor T1, second calculating means 8 for calculating a predetermined time T from the varying speed to a target set temperature, memory means 39 for storing a reference time T0, and control means 40 for comparing the time T with the time T0 to inhibit a concentrating operation even when the atmospheric temperature does not arrive at the concentration necessary temperature if the time T is shorter than the time T0. Accordingly, if the time until it reaches the set temperature is shorter even when the concentration becomes necessary during the lowering of the indoor temperature, a cooling operation is preferentially executed thereby to rapidly alter the indoor temperature to the set temperature.

Title: Combustion cylinder
Inventor: TAKEDA SHINYA
IPC: F23D3/14
Filed: 1984-05-24
Abstract: PURPOSE:To enable to hold the steady flame shape retention even under oxygen deficient condition by a method wherein the opening area of air holes located lower than air regulating rings on an inner cylinder an an outer cylinder are made larger at the near side than the far side of the air regulating rings. CONSTITUTION:Concerning air holes 2a' located lower than an air regulating ring 7 of an outer flame cylinder 2, the opening area of an air hole 2a'' located nearby the air regulating ring 7 is formed larger than an air hole 2a''' located further lower than the air hole 2a''. Further, concerning air holes 1a' located lower than an air regulating plate 9 of an inner flame cylinder 1, the opening area of an air hole 1a''' located nearby the air regulating plate 9 is formed larger than an air hole 1a''' located further lower than the air hole 1a''. Therefore, in said structure, even though the draft in a space 5 between the inner and outer cylinders is made weaker than normal condition under the oxygen deficient condition, because of the largeness of the air hole 2a'' opening area located nearby the air regulating ring, the air is sufficiently flowed into the space 5 between the inner and outer cylinders in spite of the weak draft as shown by arrow marks. Accordingly, the air is mixed with a kerosene vapor evaporated from a wick B, then the flame shape retention is continued on the air hole 2a''.

On the other hand, under the condition of the rotary shaft 1 being restrained in a standstill, according to the rotation of the pulley 10 in the direction of A, the bevel gears 29 and 30 revolve respectively in the directions of B and C and at the same time rotate about the rotary shaft 1, and therefore a bevel gear 33 rotates in the direction of A. And bevel gears 17 and 18 are rotated respectively in the directions of D and E, a bevel gear 21 is rotated in the direction of F namely in the direction opposite to A, and a gear 3 is rotated in the direction of F. This causes the spur gears 2 and 3 make relative displacement along a meandering groove 5, a table 4 moves along the groove 5, and therefore it becomes possible to move the table 4 at a high speed, to make a single motor suffice and to reduce cost.

Filed: 1988-04-28
Abstract: PURPOSE:To decrease misoperation by deciding an instruction for shift of a display area and shifting the display area to the instructed position in case a cursor touches a place near the display area and this cursor position is kept constant for a fixed time. CONSTITUTION:A CPU 2 reads the position of a cursor 5 displayed on a display screen 4 and decides whether the cursor 5 touches a side of a display area 7 or not. If so, the position of the cursor 5 is read again. Then an instruction is decided for a panning process of the area 7 in case the cursor 5 is kept at a place near the area 7 for a fixed time. Then the shift direction and the shift amount of the area 7 are decided based on the position of a mouse 3. Thus the area 7 is shifted. In such a way, the misoperations are decreased with a display area shift device.
