Filed: 1992-09-16
Abstract: PURPOSE:To provide a novel element structure capable of avoiding any adhering or fixing matters to an active layer part of the crystal end of an element requiring of photoinput and output. CONSTITUTION:The means of avoiding any adhering or fixing matters to an active layer part of a crystal end are composed of the two methods i.e., the fisrt method of forming recessions 22 above an active layer of a semiconductor element using the characteristics of crystalline growth and the second method of forming recessions near the crystal end by chemical etching step or dry etching step even if any protrusions 21 are located above the active layer. In such a constitution, polyethylene, etc., used during the crystalline cleavage time scraped off by the crystal end can be avoided. Through these procedures, the adhering matterns to the crystal end can be avoided neither deteriorating the perormances of the semiconductor element nor increasing the photocoupling loss between the semiconductor elements thereby increasing the manufacturing yield of the elements.

Title: Torque detector
Inventor: NAKAMURA HIROYUKI
IPC: G01L3/10
Filed: 1991-09-26
Abstract: PURPOSE:To obtain a torque detector capable of preventing the generation of torque detection error due to fixing work and aging change and obtaining a high torque detection accuracy with a small and simple constitution. CONSTITUTION:Magnetic record layers 12a and 12b are formed on the outer surface of rotating shaft part 10 and torque detection is performed by recording and recovering the position signal making use of the record layers. By this small and simple constitution, torque detection error generation due to fixing work and aging change is prevented. Furthermore, position signal with a specific frequency and a specific wave number is recorded in these magnetic record layers 12a and 12b. By this, position relations between individual wave shapes in the position signal wave series are specified. Therefore, it is unnecessary to consider the problem caused by the discontinuity at the connection between position signals around the outer surface of the rotation shaft part 10 as before and thus, without exactly controlling the rotation velocity of the rotation shaft part 10 during recording, high torque detection accuracy is obtained.

Title: Focus correcting device of zoom lens
Inventor: OKUDAIRA SADAO
IPC: G02B7/08
Filed: 1983-12-30
Abstract: PURPOSE:To eliminate trouble in focus adjustment every time zooming is carried out by moving a compensator lens group automatically according to a shift in focus position accompanying the movement of a variator lens group, and obtaining an in-focus state. CONSTITUTION:The position of the variator lens group 12 for zooming and the position of the compensator lens group 13 which corresponds to the position of the variator lens group 12 and is necessary for focusing are sampled according to the focas length and photogralhic distance and stored in a storage device 32. When the variator lens group 12 is shifted in position by the zooming after the focusing, position information on the compensator lens group 13 different from the current position is outputted for the focusing based upon the new position. Consequently, the compensator lens group 13 moves automatically to enter a focusing state. Thus, such trouble that a focus adjustment should be made every time the zooming is performed is eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide an optimal image average value all the time by operating the image average value at each image pickup point of an imaging device and controlling the image storage time of the imaging device so that the image average value can become a desired value with an optimal gain determined by referring to this image average value. SOLUTION: Since the image storage time of an imaging device can be controlled by a dimming part 10 so that the image average value can become the desired value, even when a photographing object or surrounding lightness is rapidly changed, automatic control is enabled so as to provide the optimal image average value (optimal image pickup state). Further, since the optimal gain is determined while referring to the image average value and the image storage time of the image pickup device 1 is controlled later so that the image average value can become the desired value with this gain, the image storage time can be controlled by switching the gain and it is possible to deal with a large change in the quantity of light as well.

The distribution of radiation counts in the direction perpendicular to the slice plane is measured, a correction coefficient or a conversion characteristic is obtained corresponding to the positional relationship with the holes 52, and thereby the nonlinearity of a position signal in the direction perpendicular to the slice plane due to the nonuniformity in the positional relationship with a scintillator 1 and a photomultiplier tube 3 is improved. When the collimator 4 is rotated in this state, the distribution of the radiation counts can be measured at all positions. This constitution makes it possible to make the device small in size, light in weight and easy to remove.
