Patent JP-S63116456-A (JP)
Title: Manufacture of semiconductor device
Inventor: NAGAKUBO YOSHIHIDE
IPC: H01L29/84
Filed: 1986-11-05
Abstract: PURPOSE:To prevent the performance of product from deteriorating by a method wherein both positive type and negative type resists inversely reacted by photoirradiation are simultaneously exposed to form two types of photoresist masks by one time photoirradiation. CONSTITUTION:Silicon nitride films previously formed is spin-coated with a negative type photoresist layer 25 to form an SiO2 26 on the film 25. A positive type photoresist layer 27 is further formed on the SiO2 film 26. Next, a region to form an N<->field inversion preventive layer is exposed to form a part 25' exposed by negative type photoresist as well as to form another part 27' exposed by positive type photoresist. The resist layer 27 is developed to remove the part 27'. An N<-> field inversion preventive layer 28 is formed by ion implantation. The resist layer 27 is totally removed; the SiO2 film 26 is removed to be developed again; and the resist layer 25 is removed. Finally, ion is implanted to form a P<->field inversion preventive layer 29. Through these procedures, the performance of product can be prevented from deteriorating.

Title: Image forming device
Inventor: FUJITA KOICHI
IPC: B41J2/525
Filed: 1990-09-29
Abstract: PURPOSE:To improve the efficiency of rewrite of a picture data after production of error by erasing at least part of a picture data written up to a position confirmed by a position confirmation means and writing the erased picture data again into an optical picture memory. CONSTITUTION:The position of a liquid crystal cell written on the occurrence of an error is confirmed by using a signal from a rotary encoder 3 and a linear encoder 35. When a central control section 40 confirms the position, a liquid crystal cell control section 45 applies a voltage for a prescribed time to the liquid crystal cell 66. Then the applied voltage is varied to write an image data. The central control section 40 outputs a signal requesting retransmission of the image data to a host computer HC via an interface section FC. Thus, the retransmission of the image data on the liquid crystal cell whose write is already finished is prevented, and the time of the printer occupying the host computer HC is reduced on the occurrence of an error.

Filed: 1990-09-28
Abstract: PURPOSE:To enhance productivity without utilizing the technique of molding with high accuracy by curving the contact portion of a rectilinear terminal inside a connector by means of a pushing force within the elastic limit of the terminal so as to constitute the connector. CONSTITUTION:A channel 13c taking the form of a right-angled triangle is formed near each side of the through channel 13a of an insulator 13 with the slope of the channel 13c outside. Square holes 13e into each of which a jack terminal 12 is pressed and fixed at its protrusion 13b are formed at a fixed pitch in the longitudinal direction of the insulator 13 and on a line corresponding to the channel 13c of the bottom side 13d of the insulator 13. When the rectilinear jack terminal 12 is inserted from its end portion 12a into each of the square holes 13e of an insulator main body 13-1 from outside the hole 13e, the end portion 12a makes contact with the slope of the channel 13c near a portion at which the protrusion 12b of the terminal 12 reaches the square hole 13c. The terminal 12 is pushed into each of the holes 13e and then the contact 12c of the terminal 12 is curved toward the through channel 13a and also the terminal 12 is fixed at its protrusion 12b to the insulator main body 13-1.

IPC: F02F3/00
Filed: 1994-10-26
Abstract: PURPOSE: To prevent oil sticking from the circumference of a piston in an internal combustion engine so as to reduce an oil consumption amount. CONSTITUTION: In oil which flows from space to be formed on the lower side of a piston toward a clearance space 26 which consists of un-cylindrical surface 13, its flow is eliminated by a lower projection part 19, and also the oil not flow into a first passage 15 since projections of axial line direction of the first passage (notch) 15 and a second passage 28 are inconsistent with each other. As a result, excessive oil flows into an oil ring groove 5 which is communicated with the first passage 15 so as to prevent bring oil sticking. Since projections of the second passage 28 and a piston pin installing hole are matched with each other, oil which is moved to the axial line direction upper side of a piston is guided to an upper projection part 18 in the clearance space 26, and then oil flows into the piston pin installing hole so as to lubricate the piston pin sufficiently.

Title: Thermal deformation suppressing method for main spindle bearing of machine tool
Inventor: TANABE IKUO
IPC: B23Q11/14
Filed: 1992-10-01
Abstract: PURPOSE:To effectively remove the heat emitted from each main spindle bearing as a major cause of thermal deformation of a machine tool and suppress also thermal deformation of the spindle bearing by introducing a cooling oil in the over-cooled state to an inner jacket, introducing cooling oil having a temp. approx. equal to that of the machine structure to an outer jacket, and thereby cooling the main bearings concentratively. CONSTITUTION:When a machine tool machines a work, the main spindle bearings 1 run temperature to cause temp. rise therein depending upon the revolving speed and/or the load, and therefore, a cooling oil in the over-cooled state is introduced from an over-cooled oil leadout part 7 into an inner jacket 3 to cool the spindle bearings 1 concentratively so that the heat emitted therefrom is removed. A cooling oil having a temp. approx. equal to that of the structural parts of the machine tool or a temp. tuned with the room temp. is fed to an outer jacket 4 from a tuning temp. oil leadout part 8 so that the spindle bearing parts besides the spindle bearings 1 are put in over-cooled condition by this oil in over-cooled state which is led into the inner jacket 3, and thereby those parts associate with the spindle bearings 1 are precluded from risk of being over-cooled.
