Title: Processing method for semiconductor substrate
Inventor: MATSUMOTO HIROYUKI
IPC: H01L21/265
Filed: 1979-12-20
Abstract: PURPOSE:To enhance the gettering effect by implanting ions of at least two kinds of elements from the side opposite to the element forming surface of a substrate, thereafter performing gettering. CONSTITUTION:In the case B and P ions are implanted, the gettering effect does not increase by only increasing the amount of dose. The peak value of the gettering effect (life time) exists only in a specific range of dosing amount (i.e. specific mixing ratio of B and P). If the dosing amounts of B and P are set at 10<14>-10<15>cm<-3>, respectively, the peak is formed in the life time even though the individual dosing amount is relatively small, and the gettering effect is improved than in the case of single implantation of P. The lattice defects increase by the implantation of two kinds of the element ions, and the difference in the radii of the atoms of the implanted ions effectively acts. Therefore, the gettering effect is remarkably enhanced.

Title: Original platen locking device
Inventor: WATASHI MASAHIRO
IPC: G03B27/50
Filed: 1986-07-15
Abstract: PURPOSE:To accurately detect the size of an original at any time by using a lock lever itself which locks an original platen as an actuator for original size detection and decreasing the number of components, and eliminating the need for wiring between the original platen and a main copying machine and eliminate wire breaking trouble. CONSTITUTION:When the original platen 11 is positioned at its home position and the lock lever protrudes upward, an opening/closing detecting mechanism 39 operates. Even when an original presser is opened and closed and the lever 26 is elevated enough for the operation of the detecting mechanism 29, the lock state is maintained. If the original presser in the open state is closed while the original platen 11 is still locked, a lever 35 abuts on a pressure plate 37, which is pressed down within a permissible rotation range. Consequently, the lock lever 26 moves down slightly to turn off a switch 38. Consequently, the driving of an original size detecting means is timed.

Title: Creating method for process design and device thereof
Inventor: HIGUCHI SHIGEO
IPC: G06Q10/06
Filed: 1995-06-30
Abstract: PURPOSE: To provide a creating method for process design and device thereof enabling a planning engineer of poor experience to easily create a process design according to a working condition without complicated treatment. CONSTITUTION: The process design is created considering working conditions such as workers' skill, workshop status, etc. Namely, working hours for each working process referred to in the case of making the process design are calculated in accordance with the working conditions. For example, when the working hours for the work process to by analyzed are considered to depend on the degree of the workers' skill and a user inputs a rate of workers of experience longer than five years in this system, a process network creating part 24 performing a fuzzy operation calculates working hours from the rate based on a theory, 'the more workers with a high skill, the less working hours', that has been theorized by experiential knowledge of experts.  Thus, by theorizing the relationship between the working conditions and the working hours based on experts' experiential knowledge in advance and objectively expressing these abstract expressions by using a membership function, even a planning engineer of poor experience can easily create the process design on the basis of experiential knowledge.

Title: Flow rate controller
Inventor: KADA MICHIO
IPC: G01N1/00
Filed: 1985-07-27
Abstract: PURPOSE:To improve the freedom of control at the time of abnormal flow rates to a large extent, by slightly shifting the zero base of a differential amplifier corresponding to a control point from the reference base of an output signal from the differential amplifier, which generates a control signal. CONSTITUTION:A float 6 moves in a flow-rate indicating tube 7 in correspondence with the change in flow rate in a flow path 1. The position of the float 6 is detected by two photosensors 91 and 92, which are arranged on the side of the indicating tube 7 with a specified interval being provided. The detected signals are amplified by preamplifiers A1 and A2. The difference between both output signals is outputted from differential amplifier A3. The flow rate is kept at a preset value by the feedback control based on the positive or negative value of the output signal. The zero base of the differential amplifier A3 corresponding to a control point is slightly shifted from the reference base of the output signal from the differential amplifier A3. Thus, the zero bases of the differential amplifier A3 are present at only two points on the output signal from the differential amplifier A3. Therefore, the apparent control point (zero base), which is a case of erroneous control, is not present on the decreasing side of the flow rate, in which relatively large change in flow rate is liable to occur.

Title: Preventing device for rudder drifting
Inventor: OOSUMI SHIGETOSHI
IPC: B63H25/30
Filed: 1980-11-28
Abstract: PURPOSE: To make a rudder drifting preventing device small and light in size and weight by bypassing through a bypassing passage provided with an orifice a passage sectional area of a brake valve narrowed by pressure of return oil from a hydraulic cylinder to an oil tank of a steering device.  
     CONSTITUTION: When steering is missed by disturbances, a flow rate of return oil flowing from a hydraulic cylinder to an inflow inlet P of a steering device increases, and a pressure difference P 1 WP 2  at an orifice grows larger. Accordingly, a spool 12 is actuated to move leftward against a spring 16, and a passage A is narrowed to allow brake pressure to be produced in the return oil. When the brake pressure is produced, the return oil not only flows through the passage A, but runs also through a bypassing orifice 20 and flows to a runoff outlet T. As said difference pressure grows larger, the spool 12 moves further to the left to make contact with a stopper 18. At that time, the return oil changes to have prescribed brake pressure, and a rudder drifting phenomenon disappears. When the brake pressure is produced, axial force acting on the spool 12 is reduced since the return oil flows through the orifice 20.

Filed: 1981-10-19
Abstract: PURPOSE:To obtain a small-sized, inexpensive device by performing temperature control over irreducible necessary parts collectively through a receiver in response to a power-on request. CONSTITUTION:The host CPU10 on a transmitter sideIsends a power-on request to a receiver side II. In response to this request, a circuit control part 23 operates, and then a temperature detector 22a confirms whether a main control part 20 is held in readiness for operation or not. As a result, when the control part 20 is not ready, a thermomodule 22b is heated to start heating the control part 20. Then, the detector 22a, once confirming that the temperature in a box 22 attains to a prescribed value, informs the control part 23 and a polarity switch 24a that the control part 20 is held in readiness for operation. On receiving the information, the switch 24a turns on a main power source 21 and the control part 23 informs the CPU10 that reception preparations are completed. Then, data transmission starts between the transmitter sideIand receiver side II.
