Title: Production of styrene resin foam
Inventor: KAMIMURA GINKO
IPC: C08J9/14
Filed: 1992-02-19
Abstract: PURPOSE:To solve the problem of ozone layer depletion by using a specific 3C fluorinated hydrocarbon as a blowing agent in producing the title foam by mixing a styrene resin with the blowing agent at high temp. and pressure and extruding the resulting mixture into a low-pressure zone. CONSTITUTION:A styrene resin is mixed at high temp. and pressure on a single- screw extruder, etc., with a blowing agent comprising a 3C fluorinated hydrocarbon in which part or all of the hydrogen atoms are substd. by fluorine atoms. The resulting mixture is extruded into a low-pressure zone, giving the title foam. Examples of the 3C fluorinated hydrocarbon are C3H7F, C3H6F2, C3H5F3, C3H4F4, C3B3F5, C3H2H6, C3HF7, C3F8, and cyclo-C3F6. Thus is obtd. the title foam having properties equivalent to those of the conventionally obtd. foam using a chlorofluorocarbon such as dichlorodifluoromethane without the fear of ozone layer depletion.

Filed: 1991-04-02
Abstract: PURPOSE:To improve the safety of power supply to a device by switching a normal power supply line to an auxiliary power supply line when a power supply cord plug is wrongly pulled out. CONSTITUTION:When a power supply cord plug 104 is pulled out, a 'non-zero' signal is outputted to a detection bus 101. A detection circuit 5 detects the signal and informs a microprocessor 6 of the detection. The microprocessor 6 instructs a selector 4 to switch the selector input line from a selector input line 102 to another selector input line 103. When the selector 4 executes the switching, the input from the cord plug 104 side is switched to the input from a auxiliary power source 3 side.

Filed: 1978-06-12
Abstract: PURPOSE: To quickly and surely detect the abnormal running condition of a gondola such as reverse movement, slip-down or slip-up independently of the speed of the gondola.  
     CONSTITUTION: When an elevator is put in operation and a wind-up motor 16 is released from a brake, a counter 108 is released from a reset state so that the counter can perform counting. A movement direction instructor 28 makes an upward instruction signal 28a into "1" in the upward movement of the gondola and makes a downward instruction signal 28b into "1" in the downward movement of the gondola. When the gondola 10 is moved in a direction commanded by the movement direction instructor 28, an upward pulse 102a and a downward pulse 102b generated by a direction discriminator 102 are not supplied to the counter 108. When the gondola is moved in a direction opposite to that commanded by the instructor, the counter 108 counts the pulses. When the counted value has exceeded a value set by a setting unit 110, a flip-flop 112 is set to produce an emergency stop instruction signal 112a.
