Filed: 1986-01-22
Abstract: PURPOSE:To obtain an excellent photosensitive body small in image unsharpness by using photosensitive layers composed of a specified crystalline semiconductor layer of a compound of groups II-IV, and an amorphous silicon layer. CONSTITUTION:The amorphous silicon a-Si layer 2 is formed on a conductive substrate 3 usually by the plasma CVD method, preferably, using SiH4 as a material gas, and then, the layer 1 of II-IV compound semiconductor, such as ZnO, specified in crystal structure, is formed on the layer 2, most favorably, by the sputtering method using ZnO as a target, resulting in growing columnar crystals oriented in parallel to the C axis perpendicular to the substrate. Since the C axis-oriented columnar ZnO crystals are about 10mum long, and arranged densely in honeycombed structure surrounded with grain boundaries, photo carriers travel through the crystals in the columnar direction without enlarging laterally, hindered with the grain boundaries, thus permitting a good-quality sharp image to be obtained without bleeding the image lines.

IPC: G08C19/02
Filed: 1980-02-07
Abstract: PURPOSE:To convert displacement into an electric signal with simple constitution, by performing digital processing through prescribed arithmetic regarding two resonator outputs which vary in resonance frequency differing in direction mutually. CONSTITUTION:The 1st and 2nd energizing parts EX1 and EX2 that correspond to the 1st and 2nd resonators X1 and X2 equipped to elastic materials 3 and 4 coupled in a body generate resonance frequency outputs varying with the displacement of displacement force P in the opposite directions, and AND gates G1 and G2 are opened according to variation at the specific count terminal of ring counter CT to apply them to arithmetic part CA, generating positive and negative equal voltages, via alternate FETs Q1 and Q2. The positive and negative equal voltages supplied when the resonance frequency outputs outputted by the arithemtic part are in inverse proportion are integrated by output part CU and then processed by operational amplifier A to output an electric signal which is obtained by dividing the difference between both the resonance frequencies by the sum, free from an influence of the rate of variation due to temperature, and based upon the mean variation rate of the  resonance frequencies corresponding to the displacement. The constitution of the  converter is simplified because of said digital processing.

Abstract: PROBLEM TO BE SOLVED: To feed liquid stably with liquid in a completely shut out state from outside as well as preventing the damage and the like of the liquid by feeding the liquid fed from an input port to an output port by a movable body moved in an annular flow passage. SOLUTION: A spherical body 14 is moved in a flow passage 11 while rotating on its own axis, and thereby, blood fed from an input opening 3a of an input port 3 into the flow passage 11 flows from an input flow passage 12 into the flow passage 11, and then, it is discharged from an output opening 4a of an output port 4 to outside through an output flow passage 13 after the blood flows in the flow passage 11. The blood discharged rate from the output port 4 corresponds to moving speed of the spherical body 14. In this case, since the blood in the flow passage 11 is moved and discharge while pushing by a spherical outer peripheral surface of the spherical body 14, receiving of shearing force is reduced, and it is suppressed to generate heamolysis and the like of the blood. It is thus possible to supply the liquid stably as well as to prevent the damage of the liquid or heating.

Title: Signal generator
Inventor: TOYODA TAKETO
IPC: B60L3/00
Filed: 1978-02-09
Abstract: PURPOSE:To simplify the hardware by applying the hierarchical approximate system in case the sine waveform is generated over a wide range of frequency featuring a constant phase difference. CONSTITUTION:V-f converter 1 generates the rectangular wave output featuring the frequency proportional to the input voltage, and the output is counted through binary counter 2a and 2b. For ROM3a and 3b, the output level approximate to the sine wave is set previously using the value of 2a and 2b as the addresses. D/A converter 4a and 4b generates the voltage corresponding to the weighting of the output of ROM, i,e., the signal approximated to the sine wave. In case the output of ROM3a is increased by one bit to feature a specified address, reset pulse 5 is generated to reset counter 2a. In other words, counter 2b is reset when the value of counter 2a reaches a specified value. Thus, the phase difference equivalent to the difference of the value between the two counters is given to output 6a and 6b. The same result can be obtained by presetting a certain value to the counter.
