Abstract: When a raising switch (21) or a lowering switch (23) is operated in an electric blind apparatus, an MPU (34) rotates a geared motor (4) so that a take-up drum (37) winds up or unwinds a lifting tape (10) to raise/lower vanes (13) of a blind. Upon rotation of the take-up drum (37), a photointerrupter (38) generates pulse signals and the MPU (34) counts the pulse signals to judge a vertical position of the blind. When an opening or closing switch (24, 25) is operated, the MPU (34) rotates the geared motor (4) so that a ladder drum (39) is followingly rotated to wind up one of ladder cords (11) fixed to the ladder drum (39), thereby to adjust an open/close angle of the vanes (13). Following rotation of the ladder drum (39), a photointerrupter (41) supplies pulse signals to the MPU (34), which in turn counts the pulse signals to judge the open/close angle of the vanes (13).

IPC: F15B13/043
Filed: 1988-07-16
Abstract: Control valve devices, in particular for antilock device on pneumatically operatable vehicle brake systems, have a controllable inlet valve (47, 2) and a controllable outlet valve (9, 10). A pressure medium output chamber (3, 7) can be connected via the inlet valve (47, 2) to a pressure medium intake chamber (48, 50) and via the outlet valve (9, 10) to the atmosphere. 
<??>Since, in normal operation (uncontrolled operation), the reduction in pressure in the pressure medium output chamber (3, 7) occurs via the inlet valve (47, 2) and the pressure medium intake chamber (48, 50), the reduction in pressure is considerably delayed. 
<??>In order to overcome this disadvantage and to shorten the times taken for the reduction in pressure, the pressure medium intake chamber (48, 50) is subdivided into a first sub-chamber (48) connected to the inlet valve (47, 2) and a second sub-chamber (50) connected to the pressure medium intake (39), as shown in fig.1. The first sub- chamber (48) and the second sub-chamber (50) can be connected to one another via an additional valve device (38, 42) designed as a non- return valve directable onto the first sub-chamber (48) into the open position. 
<??>By this measure it is ensured that in the event of a reduction in pressure the return flow of pressure medium from the pressure medium output chamber (3, 7) occurs not via the pressure medium intake chamber (48, 50) but via the outlet valve (9, 10) directly into the atmosphere, thereby resulting in an accelerated reduction in pressure in the pressure medium output chamber (3, 7) and hence in the consuming unit.

Abstract: A refrigerant compressor (10) including a compressor housing (20) having a cylinder block (21) is disclosed. A plurality of cylinders (70) are formed around the periphery of the cylinder block (21) and a piston (71) is slidably fitted within each of the cylinders (70) and is reciprocated by a drive mechanism. A crank chamber (22) is formed between the cylinder block (21) and a front end plate (23) of the compressor housing (20). The drive mechanism includes a drive shaft (26), a rotor (40) disposed on said drive shaft (20), a slant plate with an adjustable slant angle disposed adjacent to the rotor (40), and a wobble plate (60) disposed adjacent to the slant plate. The drive shaft (26) is ro­tatably supported within the front end plate (23). Rotation of the drive shaft (26) causes rotation of the rotor (40) and the slant plate, causing nutational motion of the wobble plate (60) to reciprocate the pistons (71) within their cylinders (70). The compressor housing (20) includes a rear end plate (24) incuding suction and discharge chambers (241, 251). An inlet portion (241a) of the suction chamber (241) and an outlet portion (251a) of the discharge chamber (251) link the compressor (10) with an external fluid circuit. The inlet portion (241a) is linked to an external evaporator. A narrowed portion (243) is located between the inlet portion (241a) of the suction chamber (241) and a main portion (241b) of the suction chamber (241) and creates a pressure dif­ference therebetween. A communication path (92) links the crank chamber (22) and the suction chamber (241) and is con­trolled by a valve control means (85, 85b). When the capacity   of the compressor (10) is changed, the valve control means (85, 85b) links the crank chamber (22) with the external evaporator via the inlet portion (241a) due to the pressure difference created by the narrowed portion (243) to reduce the outlet pressure thereof, preventing a decrease in efficiency of the evaporator.

Abstract: A method for making a bipolar semiconductor device having silicide contacts (30) which is compatible with the processing steps used in the fabrication of MOS devices. The present invention includes the use of sidewall spacers (28) to limit the self-aligned implants of the extrinsic base (24) and the silicide contact (30). The device is annealed so that the diffusion of the polysilicon layer (22) which forms the emitter (38) may be controlled. Since the emitter (38) size may be controlled, the emitter (38) to base (18) contact area may be reduced resulting in improved device performance.

Controllable electro-optical directional couplers can be provided as binary optical couplers. The unconnected optical waveguide path can be terminated by means of a light absorber.

Abstract: A line deflection stage comprises a line oscillator (LO), a driver (DR) and a line output transistor (TR1) the collector of which is connected through the parallel arrangement of a switching transistor (TR2) and a diode (D3) to a line deflection coil (Ly) and a scan capacitor (C s ). The deflection coil (Ly) and scan capacitor (C s ) are shunted by a diode (D2) whilst a flyback capacitor (C f ) is connected across the emitter-collector path of transistor (TR1). The line oscillator (LO) output is also applied to an input of a flyback time controller (TC) which produces a pulse output under the control of a control input (C). This pulse output is amplified by a further transistor (TR3) and an associated transformer (T) and applied to the base of transistor (TR2) to cut this transistor off for a controlled part of the flyback period to prevent the flyback capacitor immediately discharging and hence extend the flyback period.
