Title: Constant-current circuit
Inventor: MATSUYAMA EIICHI
IPC: G05F3/26
Filed: 1987-01-16
Abstract: PURPOSE:To obtain a constant-current being equal to a reference current with high accuracy by simple circuit constitution, by supplying a base current of each transistor for constituting a current mirror by an operational amplifier. CONSTITUTION:An operational amplifier 2 is inserted between the collector and the base of a transistor Q1. A collector current IC2 of a transistor Q2 is made the same as a collector current IC1 of the transistor Q1. Also, the operational amplifier 2 is a high impedance input, therefore, a reference current I1 by a current source I does not flow to the operational amplifier 2. That is to say, a base current IB of the transistors Q1, Q2 is supplied from the operational amplifier 2, and not supplied from the reference current I1 by the current source I. Accordingly, even when the base current IB takes a value which is not negligible to the collector current IC1 of the transistor Q1 due to a reason why a current amplifier of the transistor Q1 is low, etc., the collector current IC1 of the transistor Q1 shows a value being equal to the reference current I1 of the current source I. Therefore, the collector current IC2 of the transistor Q2 always coincides with high accuracy with the reference current value I1 of the current source I.

Title: Data conversion system
Inventor: KIMURA MASAYUKI
IPC: G06K9/44
Filed: 1990-01-19
Abstract: PURPOSE:To increase the processing speed in a line thinning operation, etc., by deciding the output data based on the value of the data on an area except the specific one and outputting the output data when an instruction signal is applied from a memory. CONSTITUTION:An arithmetic means 3 outputs its data when an instruction signal is outputted from a memory 2 so as to obtain a white or black center dot. Then the means 3 decides whether the center dot and its periperal ones are white or black with application of the signals which point the peripheral dots. The cells are formed in a systolic array and therefore the data D3 outputted from the means 3 is also applied to the corresponding cell of the next stage as well as to the cell contiguous to the corresponding cell, and the subsequent contiguous cells. Thus the line thinned data can be obtained from the cell as long as the line thinning data, for example, is stored in the memory 2.

IPC: G01R31/26
Filed: 1984-01-20
Abstract: PURPOSE:To enable continuous inspection and other operations for an SO package type IC by arranging contact probes on both sides thereof in parallel so as to approach or separate from the IC in linkage therewith. CONSTITUTION:An SO package type IC6 separated with a separation mechanism is conveyed into an IC chute 5 inclined by about 60 deg. from the level. Then, at the contact position, the IC is stopped with a stopper 7 and contact probes having contact pins 8 are moved toward IC6 from both sides thereof 6 in the chute 5. At this point, the pins 8 get in contact with terminals 4 of the IC6 and further grasp the IC6 compressing internal springs 9 thereof 8. Then, after the end of the operation such as inspection, the pins 8 are retreated to release the IC6 and the stopper 7 lowers to allow the IC6 to be discharged from the chute 5 freely dropping. Thus, the operation such as inspection of the SO package type IC can be done continuously while the simple construction enables the manufacture at a relatively low cost.

Title: Color liquid crystal display element
Inventor: SAKAI KAZUHIRO
IPC: G02F1/1335
Filed: 1995-01-25
Abstract: PURPOSE: To orient liquid crystal molecules all over the pixel part in a good orientation state and to enable a color image display of high quality by forming color filters in such a manner that the thickness ratio of the color filter of each color to the thickness of the liquid crystal layer corresponding to the color filter is controlled to a specified value or smaller. CONSTITUTION: The color filters are formed in such a manner that the thickness t of each color filter 5R, 5G, 5B and the thickness d of the liquid crystal layer 8 corresponding to the color filter of each color satisfy the relation of t/d<=0.19. Compared to a conventional liquid crystal display element having t/d ranging from 0.283 to 0.211, even when the liquid crystal layer thickness d is same, the color filter is made thin. Therefore, the height of overlapped part on edges of color filters can be made smaller and the projections of an orienting film 6 to be formed on the overlapped part can be made thin. The area around the projections can be enough rubbed in the orienting treatment, and by orienting the film 6 almost along the longitudinal direction of the overlapped part of filter edges, the area around the projections in the orienting film 6 can be more sufficiently rubbed.

Title: Rotary transmission device
Inventor: ITO KENICHIRO
IPC: F16H48/42
Filed: 1991-01-30
Abstract: PURPOSE:To ensure the transmission of both normal and reverse rotations of a rotary shaft to an outer race by changing over the transmission of a drive to the output side. CONSTITUTION:A sprag 23 joining with the engaging surface due to the reversal directional and relative rotations of an input shaft 2 and holder 6 and a resilient member for holding the sprag in a neutral condition are incorporated in pockets of holders 6, 7 provided between engaging surface 4, 5 which are formed respectively on the opposed surface of outer ring 1 and input shaft 2. The holder 6 and the input shaft 2 are coupled together by means of pins 18, 21 while a gap in a rotational direction is formed between the coupling parts of the pin 18 and the input shaft, and the input shaft 2 is coupled thereto with a differential means 12 for retarding the rotation speed of the input shaft 2. When an input ring 8 coupled to the pin 18 is rotated, a control shaft 16 is rotated, relative to the input shaft by a degree corresponding to the rotating direction gap, and accordingly, the sprag 23 is inclined by the relative movement between the holders 6, 7, resulting in engaging operation. In this condition, if the rotational speed of the outer race 1 is higher than that of the input shaft 2, the outer race overruns, with respect to the sprag. On the contrary, if the former is lower than the latter, a drive force is transmitted to the outer ring through engagement between the sprag and the engaging surfaces.
