Title: Manufacture of semiconductor device
Inventor: FUKUMOTO MASANORI
IPC: H01L21/336
Filed: 1987-01-23
Abstract: PURPOSE:To realize the good insulation performance without causing short- circuit, even when a pattern having only a little tolerance for photomask alignment is included, by a method wherein, after a contact window has been opened in an insulating film, another thin insulating film is applied to the whole surface, the thin insulating film is etched only in the vertical direction and the uniformly thin insulating film is left on the vertical sidewall. CONSTITUTION:When displacement in the right direction is caused due to the mask alignment, the edge of a contact window on a source 5' coincides with the edge of a polycrystalline silicon gate electrode 4, and another contact window on a drain 5 is overlapped with a thick SiO2 film 2. Accordingly, also the SiO2 film 2 is etched partially and a groove 9 is formed; a drain junction face is sometimes exposed at the groove 9. Because the groove 9 is buried with a plasma SiOX film whose film thickness is about 50 nm, the drain junction face is not exposed. Accordingly, even when an aluminum electrode 11 is formed in the state that the position of the contact window is displaced a little from a prescribed position, no electrical short-circuit is caused between the gate electrode 4 and the source 5' or between the drain 5 and a substrate 1.

Title: Discharge lamp lighting device
Inventor: YAMAMOTO AKIRA
IPC: H05B41/24
Filed: 1988-01-26
Abstract: PURPOSE:To prevent an over current to a switching element by connecting a voltage detection circuit to both ends of capacitance for pre-heating of a discharge lamp together with controlling the output control part by output of the AND working part at the time of detecting an H level. CONSTITUTION:When both ends of a discharge lamp 2 are not connected, both of the voltage detection circuits 4 and 5 send output of an 1 level to the AND working part 6 so as to make output of the working part 6 L and the output control part 7 stops oscillation of a high frequency power supply device 1. When both ends of the discharge lamp 2 are connected, output both of the circuits 4 and 5 becomes an H level and output of the AND working part 6 also becomes the H level so as to start oscillation of the power supply device 1 with output of the control part 7. As oscillation surely starts from a state of high frequency, an overcurrent is prevented from flowing to a switching element of the device 1 to break the element, while being able to prevent from lowering a life of the discharge lamp by surely providing a pre-heating period.

IPC: B21B1/22
Filed: 1980-02-08
Abstract: PURPOSE:To efficiently, exactly carry out the edging work for the rolled material, by installing a small-diameter horizontal roll to near the edging roll. CONSTITUTION:Two couples of upper and lower horizontal rolls 14, 15, are installed between the edging rolls 2, 2, so as to place axes of horizontal rolls 14, 15, on respective end planes of the edging rolls 2, 2.

IPC: G11B21/12
Filed: 1989-01-25
Abstract: PURPOSE:To reduce the thickness of a floppy disk device by using a coupling member to secure the connection between a carriage and a head arm, and reducing the angle of elevation of the head arm in an unloaded state. CONSTITUTION:When a recording medium 14 is put into a main body, a receiver 18 moves down toward a spindle mechanism and a head arm 13 also moved down. Then an S1 head 12 touches the surface of the medium 14 and is loaded. An S0 head 10 has a table contact with the rear surface of the medium 14 with the pressing force of the head 12. When the medium 14 is ejected, the arm 13 moves up and the head 12 is detached from the surface of the medium 14. Thus the head 12 is unloaded. In such a case, the arm 13 is freely moved up and down with elastically of a plate spring member 21. In the unloaded state, the angle of elevation of the arm 13 is reduced, therefore the height value is also reduced. Thus the thickness of a floppy disk device is reduced.

Filed: 1978-02-15
Abstract: PURPOSE: To obtain low slag sintered iron ore with superior low temp. reduction powdering index and falling strength by regulating the grain size distribution of SiO 2  and CaO sources in blended raw materials, and the total SiO 2  content and basicity of the raw materials in manufacture of the ore.  
     CONSTITUTION: In sintering of fine iron ore with a Dwight-Lloyd type sintering machine, formation of blast furnace slag is reduced as the SiO 2  and CaO contents of raw materials are lowered, yet the low temp. reduction powdering index of sintered ore is raised and the falling strength decreased. In blending of sintering raw materials, the total SiO 2  content of the materials is regulated to below 5.4% and the basicity (CaO/SiO 2 ) to 1.3W2.0. Assuming that the CaO and SiO 2  contents of the blended raw materials are 100%, respectively, the grain size of CaO source such as limestone and that of SiO 2  source such as silica are regulated so that more than 55% of each source is below 1 mm. The resulting sintered ore has superior characteristics such as small low temp. reduction powdering index and high falling strength although it is low slag ore.

Abstract: PURPOSE:To reduce the capacity of a driving circuit, by applying velocity control so as to reduce the speed of a driving wheel being positioned on a side to which the direction of a traveling vehicle is intended to be changed. CONSTITUTION:A steering control method for an automatic traveling vehicle is performed by inputting the travel targeted speed Vc and the vehicle body displacement quantity Ye of the traveling vehicle and performing prescribed arithmetic calculation, and by using speed command signals V1 and V2 obtained in the above calculation motors 7-8 are driven and controlled via velocity control circuits 12-13. The above control is performed in such a way that the motor 8 is controlled so that the speed V2 of a left driving wheel 2 is reduced without increasing the speed V1 of a right driving wheel 1 when the displacement quantity Ye is set as Ye<0, and also, when it is Ye<0, the motor 7 is controlled so that the speed V1 of the right driving wheel 1 is reduced without increasing the speed V2 of the left driving wheel 2. In such a way, since both traveling speed V1 and V2 do not exceed the travel targeted speed Vc, the operation of the motors 7-8 within rated speed can be authorized.
