Title: Cylindrical fluid sealing type mount device
Inventor: MURAMATSU ATSUSHI
IPC: F16F13/14
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent distorted deformation in an outer casing metal in providing a mount main body in such a state that the outer casing metal is fitted and fixed around a metal sleeve by reducing the diameter of the outer casing metal, by setting the outer casing metal into a C-shaped section having a slit extending continuously in the axial direction. SOLUTION: An outer metal cylinder 14 is externally inserted around a metal sleeve 34 of a main body rubber elastic body 16 and made to reduce its diameter so as to be fitted and fixed around the outer circumferential face, thereby forming a mount main body 18. The outer metal cylinder 14 is press fixed to the mount main body in the installation hole 20 of a bracket 22 so as to be assembled into an engine mount 10. A slit 76 extending continuously in the axial direction with a prescribed width is formed in a point on the circumference in the outer metal cylinder 14 so that its section has approximately C shape.  The stress generated in the outer metal cylinder 14 can be reduced by reducing the opening width of the slit 76 by a diameter-reducing work in fitting the outer metal cylinder 14 around the metal sleeve 34 and a diameter- reducing work in its press fitting into the installation hole 20 of the bracket 22 so that the distorted deformation of the outer metal cylinder 14 can be prevented.

Filed: 1994-03-30
Abstract: PURPOSE:To enable an air fuel ratio to be controlled for a minimum combustion by a method wherein a parameter of a lower limit value of a fuel flow rate is changed when an air flow rate is a lower limit allowable value or less. CONSTITUTION:A reducing state of an air flow rate control signal SA is detected by an air flow rate control signal comparator 1.7. A changing-over signal is outputted to a parameter changing-over relay 21 when it is judged that a difference between the air flow rate control signal SA and a lower limit allowable value SAL set at a control signal limiter 16 is less than 0. Then, the parameter changing-over relay 21 operates to turn off a contact point 21a and turn on a contact point 21b. With such an arrangement as above, a set signal for a lower level setting device 121a of a first signal control part 121 is changed over from a parameter K3 of a first parameter setting device 18 to a parameter K3' of a second parameter setting device 19 so as to forcedly expand a lower limit value range of an air fuel ratio in a fuel flow rate control system.

Title: Clad silicon substrate and its manufacture
Inventor: TANIGUCHI TORU
IPC: H01L27/12
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To raise joint strength of a clad silicon substrate, with an impurity diffusion surface as clad surface. SOLUTION: A silicon wafer is placed on a wafer holding table, and its impurity diffusion surface is finish-polished. With a polishing liquid fed, a polishing head is press-contacted to a wafer surface while it is rotated, to finish/ polish by 0.1μm. Even such wafer as impurity is diffused in high concentration, a surface roughness (haze level of about 0.2ppm) equal to such wafer of non- diffusion is obtained. In addition, a value of 4nm or below (a value over this causes degradation in strength and rough surface) is obtained as P-V (peak to valley) value. As a result, a clad strength is increased, to reduce occurrence of such defective product as peeling of silicon wafer.

Title: Continuous rotary-angle detecting method
Inventor: MORIMOTO AKIRA
IPC: B25J19/02
Filed: 1988-03-17
Abstract: PURPOSE:To make it possible to detect a rotary angle continuously so that a position signal can be taken out continuously for any rotary angle, by coaxially fixing two one-rotation type potentiometers (sensors) so that dead zones are deviated to each other. CONSTITUTION:Two one-rotation type potentiometers are coaxially fixed. The positions of dead zones A of the potentiometer (sensor 1) shown on Figure (a) and the potentiometer (sensor 2) shown on Figure (b) are deviated by about 180 deg.. Until the voltage of the sensor 1 exceeds an upper critical value or a lower critical value, the voltage can be used as an output voltage. When the voltage exceeds both critical values, it is judged that the sensor enters into the dead zone A. The voltage is switched to the voltage of the sensor 2, and said voltage is used as the output voltage. A flag which indicates that the voltage of the sensor is used as the output voltage is made to appear at each of the sensors 1 and 2 in this case. Since the dead zones are offset by the combination of the sensors 1 and 2, the rotary angle can be detected continuously.
