Title: Optical position detector
Inventor: TSUKADA EIICHI
IPC: G01D5/30
Filed: 1981-03-13
Abstract: PURPOSE:To detect positions having a fine internal at a high speed and with high precision by forming two spots on a fixed scale which has position detection marks at prescribed pitch by splitting and focusing luminuous flux from a light source, and then detecting their reflected light beams by a movable optical system. CONSTITUTION:A read head 2 movable in a direction AB is opposed to a fixed scale 1 having black-and-white marks of width l/2 at pitch (l). Light from a semiconductor laser 3, polarized at 45 deg. to a paper surface, is reflected by the 1st polarizing prism 6 after passing through a collimator lens 4, and then focused (spot diameter l/2) on the fixed scale 1 through a quarter-wavelength plate 7  and a condenser lens 8; and its reflected light travels backward to illuminate a  photodetecting element 9 through a polarizing film 5. The reflected light of the  light spot transmitted through the polarizing film 5, on the other hand, is detected by a photodetecting element 15 similarly. Thus, positions having a fine interval are detected at a high speed and with high precision.

Title: Heat sensitive actuator
Inventor: TODOROKI TSUNEHIKO
IPC: F03G7/06
Filed: 1983-03-07
Abstract: PURPOSE:To make a hysteresis range smaller, by combining opposed bias load with a form memory alloy, while setting the effective range of an actuator down to less than 1.5% at a shearing strain as a deformation variable in the form memory alloy. CONSTITUTION:A weight (weighted M1 and M2) 2 is hung down from a coil spring 1 of a form memory alloy wire, and further a stopper 11 is attached to the coil spring 1 so as to make the weight 2 stoppable at an optional position, then the spring 1 is heated at the normal temperature or 80 deg.C and cooled. As for a relationship between temperature and displacement of the weight 2, when a shearing strain value gamma goes beyond range of 1.5%, a hysteresis range suddenly increases. Accordingly, a displacement value in the effective range of an actuator is adjusted and set down to less than 1.5% as the shearing strain value of a form memory alloy whereby the hysteresis range can be made smaller.

Title: Air-fuel ratio control method for internal combustion engine
Inventor: YAEGASHI TAKEHISA
IPC: F02D41/14
Filed: 1982-03-08
Abstract: PURPOSE:To prevent the occurence of idle hunting by a method wherein the constant of integration of the air-fuel ratio feedback control system of the engine using an air-fuel ratio sensor  provided in exhaust gases is increased or decreased in proportion to the number of revolutions  of the engine in the ordinary operation condition and the constant of integration is made to  fall within a predetermined different range when the engine is idled. CONSTITUTION:An air-fuel ration control device which receives as inputs the outputs of an air  intake amount sensor, a throttle opening degree sensor, an r.p.m. sensor and etc. judges at Step  101 whether or not the engine is idled and if not, then it judges at Step 103 whether or not  the engine r.p.m. (NE) is less than the proportional upper limit r.p.m. (NEU) corresponding to  the upper limit value of the constant of integration of the air-fuel ratio feedback control system. Further, it judges at Step 105 whether or not the r.p.m. (NE) is larger than the proportional lower limit r.p.m. (NEL) corresponding to the lower limit value of the above mentioned  constant of integration. Thus the air-fuel ratio control device calculates a value (K) to be  added to, or deducted from, the constant of integration every single revolution of the engine,  on the bases of the results of its judgements. On the other hand, when the engine is idled, the  device calculates the value (K) at Step 102 by dividing a predetermined value (KI) fitted for  the idle operation of the engine by the engine r.p.m. (NE).

Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To always execute equal transfer by updating priority only when the output of a selection circuit is equal to the output of an intra-word counter. SOLUTION: A channel priority management part 7-2 compares the output of the intra-word transfer number count part 7-5 whose one bus access termination is not informed by a bus access control part 7-1 with the initial value of a transfer counter, which is obtained by a bus width comparison part 7-5-1. When they are equal, the channel number of the highest priority is selected among the plural channels requesting transfer. The bus width comparison part 7-5-1 compares the number of count up bytes among the channels, and obtains the number of the bytes of L.C.M. The respective intra-word transfer counters 7-5-2 and the channel priority control part 7-2 are informed so that a value obtained by reducing only one from the number of the bytes of L.C.M is set to be the initial value of the intra-word transfer number counter 7-5-2.
