Title: Transfer apparatus
Inventor: OKA FUMIO
IPC: H01L21/67
Filed: 1988-11-07
Abstract: PURPOSE:To execute a replacement operation without relying on an operator's memory or the like by installing a means to display the timing for replacement of an object to be treated for dummy use when the limited number of usable times, of the object to be treated for dummy use, which has been set in advance for each treatment content of a treatment container has been reached. CONSTITUTION:A control part 60 increases the number of used times whenever a batch treatment of a wafer 11 for treatment use mounted on a port 5 as a treatment container has been finished; after the treatment has been finished, the control part reads out the limited number of usable times which has been set in advance by a memory 64; the control part compares the current number of used times with the limited number of usable times. Only when both of the number of times coincide, a display, e.g., an alarm 68, is driven. Accordingly, it is possible to surely recognize the proper timing for replacement in such a way that an operator need not pay attention to anything about the timing for replacement which relied on the operator's experience and memory in a conventional method.

A cassette lever 5 is operated when the cassette 7 on the ribbon frame 4 is detached and a leaf spring 6 raises the cassette 7 mounted on the ribbon frame 4 upwardly. At this time, the projection 4a prevents the leading end of the cassette 7 from rotating downwardly. The cassette 7 has the hole 7a engaging with the projection 4b. By this constitution, the positional determination of the cassette in the up-and-down direction is easily realized.

Filed: 1992-09-30
Abstract: PURPOSE:To prevent excessive force from acting upon a casing and other components or joint parts due to the expansion of an operating fluid in association with temperature rise. CONSTITUTION:An auxiliary fluid chamber 3 is formed at the partition part of a casing, and the chamber 3 is communicated with a chamber filled with an operating fluid by a groove 6 formed at a flow member 7.

Title: Vehicular four-wheel drive control device
Inventor: KONO KAZUYUKI
IPC: B60K23/08
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To restrain or prevent hunting of control even if tires with different diameters are mounted on either the front or rear wheels by varying the amounts of driving forces allocated, so that the driving force on the auxiliary driving wheel side is kept at a minimum fixed value when the vehicle is running at a predetermined reference speed or more that exceeds its idle speed. SOLUTION: When a vehicle travels at normal speed with tires of different diameters mounted on either the front or rear wheels, a speed difference ΔVw between the front and rear wheels increases (S1 to S6). As the speed difference ΔVw between the front and rear wheels increases, feedback control of the amounts of driving forces allocated to the front and rear wheels is executed so that torque Tq1 allocated to the first front wheel increases; thereby hunting of control whereby a state in which the engagement force of a clutch mechanism is greatly increased or decreased is repeated tends to occur, but the torque Tq1 allocated to the first front wheel is corrected and set to a lower value (S7).  Therefore even if the speed difference ΔVw between the front and rear wheels increases, the clutch mechanism is kept in a fixed minimum engaged state, so that the driving force allocated to the front wheel serving as the auxiliary driving wheel is held constant.
