Title: Optical torque detecting device
Inventor: HITOMI YUTAKA
IPC: G01L3/08
Filed: 1990-05-30
Abstract: PURPOSE:To easily measure torque which differs in dynamic range by providing stripe patterns which differ in tilt angle to an outer cylinder holder and an inner cylinder holder and forming plural kinds of moire stripes. CONSTITUTION:When torque is applied to a rotary shaft 5, a torsion bar 1 twists. Consequently, the inner cylinder holder 25 rotates and moves about the outer cylinder holder 23. The extent of the deformation is detected by the light of an LED 29 which is projected on image sensors 31 and 33. The torque of the rotary shaft is detected from the detection result. When stripe intervals of the moire stripes are '1' in this case, the movement quantity of the moire stripes can not be covered. When, however, the stripe intervals are (n), on the other hand, the movement quantity of the moire stripes can be covered. Therefore, moire stripes which differ in stripe interval can be offered without replacing the inner cylinder holder 23 and inner cylinder holder 25 which constitute the moire stripes, and the torque corresponding to plural dynamic ranges can easily be measured.

Title: Reception processing system
Inventor: UENISHI MASARU
IPC: H04L7/00
Filed: 1992-05-29
Abstract: PURPOSE:To discriminate bits by sampling and discriminating only one of first half and latter areas of a cell to receive data after settlement of bit synchronism. CONSTITUTION:When data 5 is received, counting is continued till the arrival of the timing at a reference value; and when it arrives at the reference value, sampling is started, and a timer is restarted. This operation can sample only a rear cell 8 as the latter area of a Manchester code. After this sampling is performed a prescribed number of times, the sampling result is discriminated by majority decision. This discrimination is performed only in the rear cell 8, and logical '1' is decided when the frequency of the high level is smaller than that of the low level, but logical '0' is decided when the frequency of the high level is smaller. Thus, the bit processing is performed with a half processing volume because of sampling of only the latter part. The same result is obtained when only a front cell 7 as the first half area is sampled.

Abstract: PURPOSE: To accurately grown a thin epitaxial layer by maximizing the passing velocity of Cl atoms transiently caused during growing an upper 3-element material layer and lower 2-element material layer between both layers to thereby lowering the growing rate. CONSTITUTION: When a thin GaAlAs epitaxial layer 102 of about 10nm and e.g. an InP epitaxial layer 104 of about 500nm thick are grown on an InP epitaxial layer 100, very thin 4-element layers 101, 103 of about 1nm are grown during dislocation between the layers 100, 102 and 102, 104. At this time the velocity of Cl atoms passing through the layers 101 and 103 is controlled to be max. To do this, the deposition temp. is selected between 600 and 640 deg.C and mole fraction of InCl is controlled to be 1×10<-3> -4×10<-3> during growth of GaInAs and InP. This reduces the growth rate to about 2μm/hr., thus facilitating the growth rate control and providing a specified compsn.
