Title: Optical pickup device
Inventor: NAGAHAMA TOSHIYA
IPC: G11B7/09
Filed: 1988-06-23
Abstract: PURPOSE:To obtain a satisfactory tracking error signal by setting the effective photodetecting areas of two photodetecting parts at different values and therefore securing the same photodetecting value of the stray light between both photodetecting parts which detect the tracking error. CONSTITUTION:The same photodetecting value must be received by the photodetecting parts 7e and 7f as long as a correct tracking action is carried out based on a 3-spot method. In this case, however, both pats 7e and 7f receive the reflected light from the diffraction elements 2 and 3 in addition to the reflected light of a recording carrier 6. The luminous intensity distribution of said reflected light is oval and not uniform and therefore the difference is produced between the output signals of both parts 7e and 7f and the tracking error signal has an offset. In this respect, the effective photodetecting areas of both parts 7e and 7f are set different from each other so that the same quantity of light is received by both parts 7e and 7f at the position of a photodetecting element 7. Thus the tracking error signal has no offset.

Title: Run controller for trackless car
Inventor: MORI MINORU
IPC: G05D1/02
Filed: 1986-07-04
Abstract: PURPOSE:To hold the reliability and operating rate of a trackless car high by driving the car according to a normal pattern when its direction at the start coincides with the last direction or an acceleration or deceleration speed pattern when not. CONSTITUTION:When the running direction of the car body at its start coincides with the last direction, a forward direction is set in a route computing element 2, the selection command of the speed pattern in a figure (b) is outputted from a direction comparator 4 to a run control circuit 11, and a count command is not outputted to a pulse counter 7. The circuit 11, therefore, controls driving motors 14A and 14B with a start command 17 according to the pattern in the figure (b). When a backward run is made unlike before, the direction is set in the computing element 2, the selection command of the speed pattern in a figure (a) is outputted from the comparator 4 to the circuit 11, and the count output is outputted to the counter 7. The counter 7 counts pulses from pulse generators 16A and 16B, one by one, and outputs the end of counting to the circuit 11 when counting up to a set counted value (time point a). Consequently, the car body runs fast after an acceleration run.

Title: Method of controlling electronic expansion valve
Inventor: ASAI SETSUO
IPC: F25B47/02
Filed: 1987-06-26
Abstract: PURPOSE: To optimally control a refrigerating cycle by detecting and comparing temperatures before and after an expansion valve and a temperature of a compressor suction unit by an expansion valve control microcomputer, discriminating between cooling and heating regardless of a unit control microcomputer, and controlling the valve during defrosting so that compressor suction unit superheat of a reverse cycle becomes constant. CONSTITUTION: In a refrigerating cycle, a refrigerant output from a compressor 1 is air-cooled by an outdoor heat exchanger 3 via a four-way valve 2, and pressure- reduced by an expansion valve 4. Temperatures before and after it are measured by thermistors 8, 9. The pressure-reduced refrigerant cools by an indoor heat exchanger 5. The refrigerant is sensed at its temperature by a thermistor 7 immediately before suction to the compressor 1 via a liquid reservoir (b) through the valve 2, and the valve 4 is controlled. A defrosting operation upon heating is controlled by the expansion valve. And, since a maximum limit cycle low pressure is operated at a higher value while a suitable superheated refrigerant gas is ensured to the compressor, a compressor input can be increased.  And, its low pressure is controlled to higher, a refrigerant flow rate during defrosting is increased to easily obtain a defrosting heat source, and a defrosting time is shortened.

IPC: H03K17/95
Filed: 1984-07-27
Abstract: PURPOSE:To improve the response speed of a proximity switch by allowing a comparator circuit to detect the reduction in an oscillated output after the proximity switch selects an object so as to increase a current feedback from a current mirrir circuit to an oscillator thereby continuing the oscillation. CONSTITUTION:A voltage of an LC resonance circuit in an oscillation circuit 11 is amplified by a transistor Tr4, it is given to a current mirror circuit CM2, a mirror current of the CM2 is given to a multi-collector TR12 and 3/4 of the mirror current is given to the LC resonance circuit as the feedback current from the Tr12 and the oscillator is oscillated. When the object is parted, the oscillating level is high, a Tr16 is turned on by a signal from the comparator circuit 25 and no current mirror circuit CM is operated. When the approach of the object is detected, the oscillating level is lowered and when the level reaches a reference voltage of the comparator circuit 24, the circuit 24 transmits a detection signal to an output circuit 26. When the oscillation level is lowered further and reaches a value being a reference voltage of the circuit 25 or below, the Tr16 is turned off, the circuit CM3 is activated, a feedback current IC is fed from the Tr15 to the LC resonance circuit, the feedback amount is increased to continue the oscillation of the circuit 1.

IPC: G01N29/04
Filed: 1987-06-26
Abstract: PURPOSE:To decrease the crosstalks to be generated between discrete terminals by extending an earth terminal via an insulating member in proximity between a packing material and the discrete terminals. CONSTITUTION:The discrete terminals 11a are conducted and connected to discrete electrodes 5a between an ultrasonic oscillator 1a and the packing material 2 fixed thereto and are extended onto the material 2. Each terminal 11a is pinched or covered by the insulating member 12 to maintain the insulation between the earth terminal 10 and a metallic plate 13 or the terminal 11a. A planar terminal 10 is connected to the end of an earth electrode 6 fixed in an L shape to the probe front and side face of the oscillator 1a so that 10a, 10b and 10c are integrally formed. The metallic plate 13 and terminal 10 which can be approximated to a perfect conductor are thus formed in proximity to the terminals 11 so that the mutual inductances between the terminals 11 are decreased. The crosstalks are thus decreased.

Title: Method of adjusting resistance of thick film resistor
Inventor: KUMABAYASHI TOSHIAKI
IPC: H01C17/24
Filed: 1988-06-27
Abstract: PURPOSE:To adjust a resistance to a targeted value with a high accuracy and avoid the degradation of a strength caused by the reduction of the sectional area even if a power consumption is large by a method wherein a first thick film resistor made of material having a high resistivity is trimmed and then a second thick film resistor connected to the first one in series is trimmed. CONSTITUTION:A first thick film resistor 5 is connected between a land 3a and an intermediate land 4. On the other hand, a second thick film resistor 6 having a much smaller resistance than the first thick film resistor 5 is connected between a land 3b and the intermediate land 4. Then the length (l) of a slit 7 in the first thick film resistor 5 is extended to increase a resistance R0 between a pair of the lands 3a and 3b to a value R1 close to a targeted value R. Then the second thick film resistor 6 is trimmed to extend the length (l) of the slit 8 to increase the resistance R1 to the value R2 closer to the targeted value R. As the resistivity of the material of which the second thick film resistor 6 is made is much smaller than the resistivity of the material of which the first thick film resistor is made, the change rate of the resistance value of the second thick film resistor 6 against the change of the slit length (l) is small, so that it is easier for making the resistance closer to the targeted value R to trim the second thick film resistor 6 than to trim the first one.
