Title: Refrigerator
Inventor: OKABE YUICHI
IPC: F25D23/08
Filed: 1987-10-12
Abstract: PURPOSE: To enable a refrigerant pipe to be bent along a curved surface of a heat insulating material and a wall thickness of the refrigerant pipe to be made thin by a method wherein a through hole at a back wall of a heat insulating box is formed by a jig inserted through a through hole in an outer box when the heat insulating material is foamed and the heat insulating material surface constituting a surface of the through-pass hole is formed into a curved surface shape which is inclined in a downward direction toward the through hole. CONSTITUTION: When an outer box 2 and an inner box 3 are set in an outer jig 23 and an inner jig 24 for use in foaming and filling heat insulating material 4, the inner jig 24 is brought into contact with the inner surface of the inner box 3 and then a protrusion 25 of the outer jig 23 is inserted through the through hole 20 and reaches a through hole 21. The outer jig 23 is brought into contact with the outer box 2, the protrusion 25 connects the through hole 20 with the through hole 21 in a predetermined rate of curvature, so that the heat insulating material 4 is filled between both boxes 2, 3 to form the through-hole 11. After fixing a cooling device 7 to the inner box 3, a refrigerant suction pipe 12 placed outside the heat insulating box 5 is bent in a downward direction.  A bent part 12A is brought into contact with a curved surface 4A of the heat insulating material 4, its extremity is pushed down, so that the refrigerant suction pipe 12 is bent along the curved surface 4A in a predetermined radius. The bent part 12A is in contact with the heat insulating material 4 and its shape is a curved surface shape, so there is no fear that the pipe is broken in a goose-necked state.

Title: Range-finding device
Inventor: KO HIDEO
IPC: G03B13/36
Filed: 1989-10-03
Abstract: PURPOSE:To enlarge a distance range to which range-finding can be performed to a long distance by providing a means which divides the distance range in which range-finding accuracy can not be guaranteed into plural and outputs the distance information. CONSTITUTION:At the time of turning off an infrared light emitting diode, a signal 2 becomes at an 'H' level. When a signal 3 becomes at the 'H' level at the time of turning on the light emitting diode, a capacitor 21 is continued to be integrated in an ascending direction through resistances 16 and 17. After coninuing the integration for a specified time T, a control circuit 28 decides based on signals 5 and 6 from comparators 23 and 24 whether or not an object is infinity. When it is not infinity, as the result, the signal 2 is at the 'H' level at the time of turning on the infrared light emitting diode and the signal 3 is at the 'H' level at the time of turning off the light emitting diode, so that the capacitor 21 is integrated in a reverse direction. The control circuit 28 performs a range-finding operation by measuring a time (t) until a signal voltage V0 attains a reference constant voltage Vc since the reverse integration is started while monitoring the signal 4 from a comparator 22. Thus, the distance range to which range-finding can be performed is enlarged to a long distance.

Title: Hydraulic control device for automatic transmission
Inventor: SHIMAMOTO MASAO
IPC: B60W10/101
Filed: 1987-10-13
Abstract: PURPOSE:To prevent breakage of a clutch and a shock of a vehicle by interrupting an oil path connecting a manual valve and a backward driving means through a hydraulic directional control valve by generated oil pressure of oil pressure generating means during forward running at a high speed ratio. CONSTITUTION:A signal oil pressure of a speed change ratio control solenoid valve 301 is input to a port 183 of a hydraulic directional control valve 180, and the signal oil pressure P1 is controlled by a controller 300 in such a manner as to become low at a low speed ratio and high at a high speed ratio. Accordingly, during forward running at a high speed ratio, even if a shift lever is switched from D range to R range in error, a backward hydraulic system is interrupted by the hydraulic directional control valve 180, and as a forward-backward switching piston 150 is always urged towards forward position F by a spring 155, the lever is kept from being switched to backward driving. Thus, reliable fail-safe for misshift can be accomplished so that breakage of a driving system such as a dog clutch or the like can be prevented.
