Title: Paper feeding device and image forming device
Inventor: MUROOKA KEN
IPC: B65H3/06
Filed: 1991-05-24
Abstract: PURPOSE:To feed a separated paper sheet securely to a pair of feeding rollers provided near the downstream side of a paper feeding tray even if the paper sheets are jumped up, when the paper sheets are separated one by one by a separating claw for restricting the one corner of the sheets placed on the paper feeding tray. CONSTITUTION:A separating claw 18 for restricting the one corner of paper sheets P placed on a paper feeding tray 12 is provided and, when a paper feeding roller 17 is rotated to feed the paper sheets P, the paper sheets P are separated one by one by the separating claw 18. Also feeding rollers 20 are provided near the other corner opposite to the one corner of the paper sheets P restricted by the separating claw 18. Thus the paper sheets P are fed securely through the feeding rollers 20 since the paper sheets P are kept horizontal on the feeding roller side 20 even if they are jumped up when they are separated from each other by the separating claw 18.

Abstract: PURPOSE:To perform selection of an operation mode further matching with the feeling of a utilizer by a method wherein a range within which a room temperature is able to be set according to a decision reference value and an initial room temperature set value are decided and a decision reference value is varied according to the variation hysteresis of the room temperature set value of a utilizer. CONSTITUTION:A range within which a room temperature set value is able to be set according to a decision reference outside air temperature and an initial room temperature set value are decided by a room temperature set range deciding part F. A decision reference value varying part G is caused to learn the variation hysteresis of the room temperature set value of a utilizer and a decision reference outside air temperature is varied according to the variation hysteresis. Air-conditioning of the whole of an air-conditioner is controlled by an air-conditioning control part H according to a set temperature signal from a remote controller. In which case, the room temperature set range deciding part F and the decision reference varying part G are operated according to a program in which various controllers are prestored and a room temperature set value is decided according to a given control pattern. This constitution causes selection of an operation mode approximately matching with to the feeling of a utilizer.

Title: Piston device for internal combustion engine
Inventor: GOTO TAKAHARU
IPC: F02F3/00
Filed: 1989-05-16
Abstract: PURPOSE:To reduce oil consumption at the time of a high rotating speed of an engine by providing a plurality of communication holes for communicating the surface of a second land with the neighborhood of the groove bottom part of an oil-ring groove, and also by providing, to these holes, a valve device for allowing fluid to flow only to the oil-ring groove side from the second-land side when the pressure is greater than a prescribed value. CONSTITUTION:When the rotating speed of an engine becomes high and the pressure is gradually increased to exceed the energizing force of a spring body 11 by which a valve body 10 is energized, the gas in the gap 6a of a second land 6 passes through a horizontal hole 8 and a connecting hole 9, and flows into the back surface side of an oil ring groove 3c. Since the spacer 3b of the oil ring 3 is of a corrugated plate construction having a large number of holes, the gas passed through the spacer 3b flows out, as shown by the arrow, toward the low-pressure crankcase, and at that time, blows down the oil 14 under the oil ring 3. Since a plurality of passages are provided in the circumferential direction of a piston 1, the blow-down of the oil is carried out at almost entire circumferential places. In this case, since the valve body 10 and the spring body 11 are arranged in the horizontal position, the set pressure is hardly influenced by the inertia force in the moving direction of the piston 1.

Title: Tape end detector for tape recorder
Inventor: SASAKI HIDEMI
IPC: G11B15/08
Filed: 1987-05-18
Abstract: PURPOSE:To increase the strength of a cassette holder so as to prevent incident of external disturbed light and reduce the number of parts so as to reduce the cost, by forming the optical path between a light emitting and receiving elements by means of light leading sections formed in one body with the receiving members of the cassette holder. CONSTITUTION:A light emitting element 34 is inserted into the central hole 16 of the reel of a cassette 10 inserted into a cassette holder 22 and the light of the element 34 is projected toward light leading sections 30 of cassette receiving members 26 on both sides of the holder 22. Each of the light leading sections 30 is constituted of holes 30A-30D and a projecting section 30E. When a tape reaches its tail end and becomes transparent, the end is passed through an element 36 and bent perpendicularly at the slope 31 oof the hole 30A. Then the tail end is led to the element 35 and the end is detected. When the light leading members are formed in one body with the cassette holder in such way, the necessity of a notched member to be used for avoiding interference is eliminated and the strength of the holder is increased. Moreover, internal scattering of incident light can be prevented by the holes 30A-30D and the cost can be reduced because the number of used parts is reduced.

Title: System for allocating vector register
Inventor: MATSUO SHIGEYA
IPC: G06F9/45
Filed: 1990-05-10
Abstract: PURPOSE:To reduce the number of times of accessing to a memory and to increase the executing speed of an object program by allocating structure data having higher rates of optimization effect to vector registers not used for vectorization. CONSTITUTION:An allocatable structure data extracting means 2 extracts structure data allocatable to a vector register from all data of an original program. An allocating object structure data deciding means 3 selects the structure data allocated to the vector register based on such information as the number of vector registers, the rate of optimizing effect from the extracted structure data. A vector data allocating means 4 changes the symbol table of the structure data decided by the means 3 and allocates the changed table to the vector register. Accordingly, structure data having higher rates of optimizing effect can be allocated to a vector register not used for vectorization. Therefore, the executing speed of an object program can be increased.
