Title: Automatic paper feeding device
Inventor: SUZUKI YOSHITAKA
IPC: B41J13/02
Filed: 1994-12-28
Abstract: PURPOSE: To simplify control of a one-way clutch by a method wherein after a recording paper is conveyed to a gap between a feed roller for paper feed and a driven roller, a motor is reversed and a fed recording paper is automatically fed to the recording part side as the recording paper is nipped between the feed roller and the driven roller. CONSTITUTION: When the forward end of a recording paper 4 pusle-fed by a paper feed roller 11 is conveyed to a gap between a feed roller 19 for paper feed under a stop and a driven roller 23, a stepping motor 40 is reversed. In which case, since the feed roller 19 for paper feed is rotated counterclockwise through operation of a one-way clutch 21 and a driven roller 23 making contact with the feed roller 19 for paper feed is rotated clockwise, the recording paper is transferred to the platen roller 51 side of a recording part 50 as a recording paper 4 conveyed to a gap between the feed roller 19 for paper feed and the driven roller 23 is nipped between the two rollers 19 and 23. This constitution simplifies constitution since control of switching of a one-way clutch arranged on the paper feed roller side is effected only by reversing a motor.

Abstract: PURPOSE:To improve the certainty of handling and to improve the availability and the throughput of a device by repeating the holding operation by the required times until the adequacy is achieved when the holding is not adequate when a chucking plate is lifted up and a substrate is held. CONSTITUTION:A chucking head 14 is lifted up from a position, where a wafer 12 can be held, by DELTAZ1. The state, wherein a chucking plate 17 and the wafer 12 are almost in contact, is obtained, and the wafer 12 is sucked with vacuum. The presence or absence of the wafer 12 is detected by the detection of the pressure of the chucking plate 17 at this time. When it is judged to be present, the wafer is lifted up by DELTAZ2, and the non-contact state with the wafer cassette is obtained. On the contrary, when it is judged to be absent, the chucking head 14 is lowered by DELTAZ1. The number of the retrying times is counted. When the number of the retrying times is less than a preset times, the head is lifted up by DELTAZ1 again. The state, wherein the chucking plate 17 and the wafer 12 are almost in contact, is obtained, and the wafer 12 is detected.

Title: Heat pipe
Inventor: OGUSHI TETSURO
IPC: F28D15/02
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To decrease a pressure loss of a liquid fluid and to increase a heat transporting capability by forming an axial groove on an inner wall of a heat pipe container, bringing an outer periphery of a wick into close contact with an end of a ridge of the groove, inserting it into the container, sealing an operating liquid in the wick, and impregnating the liquid. SOLUTION: When an evaporator 8 of one axial end of a heat pipe container 2 is heated, its heat is transmitted from a ridge 11 of a groove 10 of the container 2 to a wick 3, an operating liquid 5 in the wick 3 absorbs a heat to evaporate, and hence vapor 6 is generated near the evaporator 8 in the groove 10. The vapor 6 axially flows in the groove 10 from the evaporator 8 side toward a condenser 9 side according to a temperature difference between the evaporator 8 and the condenser 9 of the container 2, and arrives at the condenser 9 as its vapor phase remains as it is. Thus, since the overall inner space can be used as a liquid channel 3a, a pressure loss of the channel 3a is reduced, and a heat transporting capability of the pipe 1 is increased.
