Title: Method of learning control ineffective stroke of piston in frictionally engaging element
Inventor: HIRAMATSU TAKEO
IPC: B60W10/10
Filed: 1987-04-20
Abstract: PURPOSE:To make it possible to shorten the time of ineffective stroke of a piston by enabling a variation in the time required for the stroke of a spool to know from the time lapse of electrical value by use of a newest learning value. CONSTITUTION:The relationship between electrical values and the stroke speed of a spool 52a is beforehand stored in memory, and the times of drive known from electrical values during the spool 52a strokes from a hydraulic pressure releasing position to a position just before the position at which the engagement between the spool and an engaging member is initiated, are multiplied by stroke speeds, respectively, and the value of ineffective stroke of the spool 52a is detected from the sum of thus multiplied values. The stored stroke value of the spool 52a is updated to thus detected ineffective stroke value of the spool 52 and is stored so that the arrival of the spool 52a at the position just before the engagement starting position is detected from the time lapse of the electrical value during the next ineffective stroke of the spool 52a. Accordingly, when there is a loss required for the stroke, the spools 52 is allowed to stroke at a higher speed thereby it is possible to shorten the time of ineffective stroke.

Title: Slip conveying device
Inventor: OBARA AKIRA
IPC: G06K9/20
Filed: 1986-04-26
Abstract: PURPOSE:To minimize the interval of a slip successively conveyed and to improve a processing speed by arranging a sensor to detect the passing of the slip between the sensor and a separate roller. CONSTITUTION:A control means stops a motor 7 while the rear edge of a slip passes through a sensor CR2, passes through a sensor CR1 and the rear edge of a next slip 3'' is detected by the sensor CR2. When the rear edge of the first slip passes through the sensor CR1, the motor 7 is turned again and the next slip is conveyed. Consequently, since the distance between slips successively conveyed depends upon the distance of the sensors CR1 and CR2 regardless of the distance with a separate roller 4 and the sensor CR1, the interval can be optionally shortened.

In this process, optionally, crystalline pieces of GaP 4 as a solute may be placed on a solvent Ga 3 in order to saturate the vapor pressure source Ga 3 with the solute P. This method enables the reduction of the concentration of open lattice of an element having higher equilibrium vapor pressure and that of an element having lower equilibrium vapor pressure at the same time in a compound semiconductor and is extremely effective for the production of a substrate for a light emitting element and a light receiving element. This process also enables the production of a substrate of a compound semiconductor having a large area, excellent homogeneity all over the area and low crystal defects.
