IPC: B60H1/00
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of air-conditioning capacity causing discomfort at the time of operating a rear cooler without controlling the air- conditioning capacity of the rear cooler. SOLUTION: When environmental conditions are read, necessary air- conditioning capacity is computed on the basis of the environmental conditions and operating conditions such as set temperature (steps 100, 102). Whether rising operation needing large air-conditioning capacity is in process and whether a rear seat air conditioner is in operation are confirmed. When rising operation is completed and the rear seat air conditioner is in operation, control is shifted to a step 108 to compute the correction quantity of air-conditioning capacity on the basis of the air-conditioning capacity of the rear seat air conditioner.  The air-conditioning capacity of a front seat air conditioner is corrected on the basis of the computed correction quantity of air-conditioning capacity, and air-conditioning operation of the front seat air conditioner is performed with the corrected air-conditioning capacity (steps 104-112).

Filed: 1988-06-06
Abstract: PURPOSE:To increase the throwing in efficiency of a switching mechanism by unifying the forms and the sizes of two links to compose a toggle link, and using parts commonly. CONSTITUTION:When a breaker is thrown in, the direction ot a switching spring 20 force given to the connection on a motive section is changed gradually by rotating an operation handle 7, and a link mechanism breaks the still condition by crossing a dead point when the direction of the motive section and the direction of the force are coincided, returning to the throwing-in condition to be the following still condition. At that time, by the redoubling function of a toggle link 14, a load amplifying the load of the switching spring 20 is presented at a pin 19 being the connection fulcrum with a movable contact maker holder, but the redoubling coefficient to indicate the redoubling level is changed by the distance between the fulcums of links 15 and 16, and it presents a high value when the value is made 1:1. And by using the links 15 and 16 commonly, the distance between the fulcrums is made just 1:1. The redoubling coefficient is increased consequently.

Title: Polymer pipe for pneumatic feeding of optical fiber
Inventor: ODAKA YOSHIFUMI
IPC: G02B6/44
Filed: 1991-06-11
Abstract: PURPOSE:To greatly prolong the forcible feeding length of an optical fiber unit or to drastically shorten the forcible feeding time by molding a pipe of a specific compsn. CONSTITUTION:The pipe 1 is molded of the compsn. prepd. by incorporating silicon graft polyethylene (PE) at 0.1 to 10% by weight into PE having >=0.94 density. Namely, there is a need for using a material having a low friction coefft. in order to enhance the forcible feeding characteristic and, therefore, the PEs are used by taking the mechanical characteristics into consideration. Since the high-density PE having the low friction coefft. as compared with the low-density PE among such PEs is used, the density is specified to >=0.94. Further, the friction coefft. is lowered by mixing the silicon graft PE which is a lubricant with the high-density PE which is a substrate material in order to enhance the forcible feeding characteristic of the pipe. This content is required to be set at 0.1 to 10% by the weight of the PE. The effect of the lubricant does not appear if the content is <0.1% by weight. A stable extrusion characteristic is not obtainable at the time of the extrusion molding operation of the polymer pipe if the content exceeds 10%.
