Title: Semiconductor integrated circuit device
Inventor: NITTA SUSUMU
IPC: H01L21/3205
Filed: 1985-09-30
Abstract: PURPOSE:To facilitate dicing, by firming a groove on a dicing line, at which at least a second input/output line passes on a wafer. CONSTITUTION:An aluminum film, which is to become a first wiring layer 17, is deposited by evaporation and the like. After patterning, a groove 20 is formed along a dicing line 7 of a wafer 1 (silicon substrate). An insulating layer 21 and a wiring layer 22 are formed by extending a first insulating layer 18 and a second wiring layer 19 in an MOS FET part (element region) so as to cross the groove 20. Since the groove 20 is a recessed groove, A part 22a of the wiring layer 22 at the end of the bottom part of the groove 20 is thinner than the other part due to a shadowing effect. Therefore cutting can be readily performed when dicing is carried out with a cutter 23. Thus the second wiring layer 19, which is continued to the wiring layer 22, in the element region, is not damaged, and the dicing can be carried out readily.

Title: Electrophotographic device
Inventor: TACHIKAWA MASAICHIROU
IPC: G03G21/00
Filed: 1983-11-17
Abstract: PURPOSE:To remove well a remaining toner on a photosensitive body with a relatively low pressing force by pressing a blade, which has a tip part to be pressed to the photosensitive body, at an angle to the direction vertical to the driving direction of the photosensitive body. CONSTITUTION:A blade 19 has a tip part 18 pressed at an angle theta to a photosensitive body 10 having a required width W. An angle B made between the side face of the blade 19 and the driving direction of an arrow 16 of the photosensitive body 10 is increased according as the angle theta of inclination is increased. In case of B>90 deg., a digging-up action can be given to a component N of force; and even in case of B<90 deg., the pressing action is weak and toner retaining due to a component T of force acts effectively when the angle B is smaller. Thus, if the same blade 19 is used and the same pressing force P is applied, a more effective toner removing action is caused when the angle theta of inclination is made larger.

Title: Speed detecting device for vehicle
Inventor: HIROSE NORIAKI
IPC: B60L3/08
Filed: 1985-09-30
Abstract: PURPOSE:To enable the vehicle speed to correctly detect from low speed to high speed regardless of the slip or skid of the wheels by providing plural speed detecting means. CONSTITUTION:When the slip or skid of wheels is not generated, a signal converted the output of a proximity switch or an encoder 6 into F/V by an F/V converter 7 is outputted as a speed signal (detection output) 20 through an analog switch 14, while when an acceleration signal or a reduced speed signal which differentiated the output of the F/V converter 7 reaches to a set level or more, the analog switch 14 is turned off and an analog switch 15 is turned on. Hereby, a signal which integrated the output of an accelerometer or an integration gyro 8 to detect the adjustable speeds in the forward and backward directions of a vehicle is outputted as the speed signal 20. If the both signals become equal, the analog switch 14 is turned on and the analog switch 15 is turned off.

Title: Bearing device for magnetic disk
Inventor: TANAKA KATSUHIKO
IPC: F16C17/02
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To prevent a lubricant of dynamic pressure fluid bearings from splashing and sticking to the magnetic disk by shutting ventilation from a lubricating oil reservoir to the outside. SOLUTION: When a coil of a stator 34 of a driving motor is electrified, rotary force is produced on a rotor 33. Consequently, the hub 25 is rotated integrally with a magnetic disk D. At this point, the hub 25 is supported in the radial direction with its sleeve part 26 keeping in noncontact with a shaft 22. Now, since no vent holes are provided on both the dynamic pressure radial fluid bearing R and the dynamic pressure thrust fluid bearing S, it is impossible that the lubricant in the bearings is splashed out of such vent holes in rotating the hub 25. Moreover, all spaces between the hub 25 and a thrust plate 29 and also the shaft 22 can be filled with the lubricant without leaving air in assemblage. Therefore, the lubricant is never leaked outside the bearings on account of expansion of air due to a temp. rise.

Title: Liquid crystal display device
Inventor: ASAHI MORIO
IPC: G09F9/00
Filed: 1986-09-13
Abstract: PURPOSE:To enable viewing of a display in a dark place as well and to solve problems of increased power consumption, cost and size by providing a light storage characteristic to a reflecting member which reflects the light transmitted through a liquid crystal layer. CONSTITUTION:External light transmits a front polarizing plate 14, front glass 12, the liquid crystal layer 11, rear glass 13 and a rear polarizing plate 15 successively in a bright place and arrives at the reflecting member 16, where the light is reflected to return forward. If a voltage is held impressed to the liquid crystal layer 11 at this time, the optical state of the liquid crystal layer 11 changes locally to change the quantity and nature of the transmitted light, by which characters and pictures are displayed on the liquid crystal layer 11. Since the reflecting member 16 is formed of a light storing material, part of the reflected light is stored in the reflecting member 16. The light is released forward from the member 16 and is transmitted through the liquid crystal layer 11 to display the characters and images when it becomes dark in the outside. The liquid crystal display is thus visible in the dark place as the member 16 acts as a light emitting source. Such device is extremely convenient.

Filed: 1987-08-31
Abstract: PURPOSE:To improve the comparing accuracy of a detecting signal by providing a changing-over switch to plural signals whose sizes are compared, sharing an amplifier with time division and causing the amplifying quantity of the plural signals to be constant. CONSTITUTION:Signal detecting elements 1a-1d receive the infrared radiation of a remote controller with a light receiving element and a clock signal is inputted from a switch changing-over signal generating means 5 to a switch changing-over control part 3e. Then, the switch changing-over control part 3e successively changes over switches 3a-3d with synchronizing to a clock. A light receiving element 1a is connected to an amplifier 4 for a Ta time and a light receiving element 1b is connected to the amplifier 4 for a Tb time. Then, respective light receiving current is amplified by the amplifier 4 and outputted to a signal comparing means 6. Thus, since the amplifier 4 is shared to the plural signal whose sizes are compared, the amplifying quantity of the respective signals is made constant. Thus, the comparing accuracy of the detecting signal can be improved.
