Title: Mask forming method
Inventor: NAKADA HIDEFUMI
IPC: G03F1/00
Filed: 1978-01-13
Abstract: PURPOSE: To secure formation of the mask in the course of the manufacturing processes of only the positive or negative resist by introducing the O 2  impurity properly into the Cr film via the ion injecting technique.  
     CONSTITUTION: Resist 3 is stacked on Cr film 2 on glass substrate 1 to form a pattern through the exposure and development. The injection amount of the O 2  ion is controlled to 0.01W0.1 or more in terms of the atom number ratio of O 2  against Cr for the O 2  density X on the surface of film 2. Then resist 3 is removed with etching via the glass plasma containing the halogen element and O 2 . Thus, ion injection region 2a remains with injection region 2b removed selectively. With this method, the Cr film of the region covered with the resist can be etched away, and accordingly the inverting process using the resist can be omitted. Furthermore, the minute processing becomes possible.

Title: Idling rotational frequency controller for internal-combustion engine
Inventor: YUZAWA HARUO
IPC: F02D41/00
Filed: 1985-01-14
Abstract: PURPOSE:To improve controllability where a solenoid valve provided in a bypass path bypassing a throttle valve is controlled to controllably feed back idling rotational frequency, by providing a heating means for heating a coil portion of the solenoid valve. CONSTITUTION:An idling rotational frequency controller interposes a solenoid valve 11 for controlling bypass flow in a bypass path 10 provided to bypass a throttle valve 7 in a throttle chamber 4, and controllably feeds back the idling rotational frequency in closing the throttle valve 7 to a desired idling rotational frequency corresponding to engine temperature, etc. by controlling the opening of the solenoid valve 11. In this case a body of the solenoid valve 11 is provided integrally in a cooling water path 41 for circulating engine cooling water to heat an electromagnetic coil in the solenoid valve 11 with high temperature cooling water. Thus, the coil temperature is maintained within a narrow temperature range to provide air flow property not affected by the atmospheric temperature and ambient temperature.

Title: Position control switch control method for servo circuit
Inventor: HASHIMOTO SHUICHI
IPC: H02P25/06
Filed: 1989-01-10
Abstract: PURPOSE:To improve the reliability of position control and to shorten a positioning time by switching operation to the position control when a switching condition does not break down within a fixed time after the switching condition is once achieved. CONSTITUTION:A main control part (MPU) 6 monitors the switching condition establishing signal of an AND gate 8c and decides whether the switching condition is established or not. When the switching condition is established, the MPU 6 starts a timer 9a. When the switching condition establishing signal is turned off within a counted time X of the timer 9a, the timer 9a is reset and the operation is returned to the decision of the switching condition establishment. On the other hand, when the switching condition establishing signal is not turned off within the time X and the switching condition is established, the timer 9a is not reset. After the timer 9a counts the time X, a coarse/fine switching signal is generated in a switch part 5 and the operation is switched to the position control by a positioning error detection circuit 4. Thus, the switching to the position control caused by the occasional establishment of the switching condition can be excluded and positioning can be executed stably at high speed.

Title: Laser heat treatment of fork shaft
Inventor: SUZUKI TAKATOSHI
IPC: C21D9/32
Filed: 1984-01-11
Abstract: PURPOSE:To harden a fork shaft while the depth from the treating surface thereof is made constant by adjusting the intensity or irradiating speed of the laser beam for irradiating the rugged part of the fork shaft according to the uphill slope and downhill slope of the rugged part. CONSTITUTION:A work shaft 25 is fixed in a home position and a laser beam 21 is oscillated; at the same time a motor 28 is operated by a control device 29 to move the shaft 25 in an arrow direction. On the other hand, the rugged part 25a of the shaft 25 is intermittently irradiated by the beam 21 past a slitter 23 through a reflecting mirror 22 and a lens 24. The slitter 23 is fully opened by the operation of the device 29 in the case of irradiating the downhill slope of the part 25a of the shaft 25 with respect to the moving direction of the laser beam. All the laser beams are therefore irradiated more intensively to the downhill slope than to the uphill slope to maintain the uniform hardening depth in each part. The depth of hardening in this case is freely adjustable according to the varying quantity to shield the laser by the slitter 23.

Title: Method for adjusting reference voltage of magneto-resistance element circuit
Inventor: MORI MASAKI
IPC: H01L43/08
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of facility costs by making laser trimming unnecessary by performing the variable processing of a voltage impressed upon a second input terminal by using an impressing voltage changing device. SOLUTION: An impressing voltage changing device 50 is mounted on a magneto- resistance element circuit 30 and a voltage supplying line 54 and a grounding conductor 55 are respectively connected to resistance connecting terminals 48 and 49. In addition, an already fixed voltage which becomes an inverting condition is applied across magneto-resistance elements MR1 and MR2 and the output signal VS corresponding to a magnetic field is inputted to a comparator 36 from a sensor section 31 through an signal input terminal 38. When the value of the voltage inputted to the terminal 48 is changed by operating the device 50, the voltage value change becomes equivalent to the change of the reference voltage of the comparator 36, because the terminal 48 is connected to a reference voltage input terminal 39.  At the same time, whether or not the compared result signal of the comparator 36 is inverted is detected from the outputting state of an output terminal 40 and, when the inversion is detected, the voltage value when the signal is inverted becomes the reference voltage of the sensor section 31. Therefore, no laser trimming is required.

CONSTITUTION: A central recess 11 is formed at a top section, and an edge section 12 is formed in a periphery. An annular hollow section is shaped to the inner circumference of a hollow body 1 in the lower section of the edge section 12. Four slots 13 are arrayed to the edge section 12 and a hollow section corresponding to the edge section at the same angular intervals. Each edge section of the slots 13 on the inside and outside of the edge section 12 is formed of wide openings 14, 15. The converging opening sections of the four slots 13 are formed in one opening 14. The cord is passed successively to the slots 13 and tied in a lower section. Even when the intervals of each two slot 13 are shortened and a neck is entered into the cord, the cord is displaced forcibly in the direction of the opening 15, and the neck is slipped off automatically.  Accordingly, even when any accident happen, the cord can be released and removed surely from the hollow body 1.
