Title: Reversible electromagnetic coupling device
Inventor: OOUCHI MASANOBU
IPC: F16D27/12
Filed: 1979-06-25
Abstract: PURPOSE: To freely switch a shaft at an outer side to a clockwise or an anticlockwise rotation, by a method wherein a gear row for an anticlockwise turning is provided outside a clockwise turning rotor and an anticlockwise turning rotor.  
     CONSTITUTION: Gears A, B, C, D and E are engaged with an outer circumferential surface of a clockwise turning rotor 7 and an anticlockwise turning rotor 8. With an exciting coil 12 charged with electricity, a magnetic flux, which passes to an amature 5 through a clockwise turning rotor 7 from a field core 13, is generated, and an excited amature 5 is adsorbed by magnetism to the clockwise turning rotor 7 against a restoring spring 6, whereby a center shaft 1 and the clockwise turning rotor 7 are united monolithically for rotation. When charging of electricity is switched to an exciting coil 19, a magnetic flux, which passes to the amature 5 through the anticlockwise rotor 8 from a field core 15, emanates, and the amature 5 is adsorbed by magnetism to the anticlockwise turning rotor 8. The rotation of the anticlockwise turning rotor 8 turns into the rotation of the clockwise turning rotor 7 through the working of the gear rows AWE, and causes a tube shaft 7b and an outer hub 10 to be rotated in a reverse direction.

Abstract: PURPOSE:To bring an area having a contrast to an image formation on an image sensor, and to exactly execute an operation of an AF mechanism, by comparing a pulse voltage of each picture element with a prescribed reference voltage, and detecting whether an image exists or not, due to a fact that the number of times of a variation exceeds a set value. CONSTITUTION:A pulse voltage Va of an image sensor 44, which is obtained by scanning an image projecting light by the image sensor 33 is compared with a prescribed reference voltage Vc, the number of times by which the continuous pulse voltage Va is brought to a high and low variation against the reference voltage Vc is counted, and whether an image exists or not is discriminated due to a fact that this counting value exceeds a set value. That is to say, the number of times by which the image is brought to a black and white inversion in the scanning direction of the image sensor 44 is derived, and it is decided that if said number of times of inversion is large, the image exists, and if it is small, the image is a background area or an image of a single color. As for the image sensor 44, a one-dimensional solid-state image sensor is suitable. In this way, an area of an image having a contrast is selected automatically, and an AF mechanism is operated correctly.

Title: Analysis of copper in solder
Inventor: ISHIGAKI HARUHISA
IPC: G01N31/00
Filed: 1982-05-17
Abstract: PURPOSE:To greatly improve both analysis accuracy and analysis recovery rate without undergoing physical interference of interfering elements by a method wherein solder is dissolved with an acid under heating, and filtrate after filtration is subjected to quantitative analysis based on the standard addition method using an atomic absorption photometer. CONSTITUTION:Solder of 0.5-1.0g as a sample is sampled, and nitric acid (1+1) 30ml is added to dissolve the solder under heating. The dissolved solder is cooled and filtered. The filtrate is separately taken out, measured at 324.7nm using an atomic absorption photometer and then subjected to quantitative analysis based on the standard addition method. As shown in the figure, the filtrate consisted of the dissolved solder is added in a certain equal amount to each of Cu standard solutions which have Cu contents stepwisely increased. The indicated amounts are plotted in order. The Cu density of the sample can be determined form the point where the resultant charactersitic curve intersects the X-axis (representing Cu content). Since all the measured solutions contain the sample solution in equal amount, the sample will not undergo any physical interference such as influence of interfering elements present in the sample, viscosity and surface tension. Thus, it becomes possible to greatly improve both analysis accuracy and analysis recovery rate.

Title: Shift control device for automatic transmission
Inventor: IWATSUKI KUNIHIRO
IPC: F16H61/08
Filed: 1990-03-29
Abstract: PURPOSE:To provide ideal shift characteristics by providing a means to detect output shaft torque, a means to calculate share torque of a friction engaging device on the disengagement side from the output shaft torque, and a means to control the oil pressure of the friction engaging device on the disengagement side depending upon share torque. CONSTITUTION:Output shaft torque is detected at a real time, and from the detecting output shaft torque, share torque (equivalent to the minimum value of non-slide torque capacity) of a friction engaging device on the disengagement side is calculated. The oil pressure of the friction engaging device is controlled depending upon the calculated share torque. Thus, control is fundamentally not control wherein a pressure is increased through detection of a slide but control wherein an oil pressure is adjusted to a value at which torque capacity can be ensured after the minimum value of torque capacity enough for prevention of the occurrence of a slide is previously calculated. Therefore, no problem on response arises and extremely stable control is practicable.
