Title: Display device
Inventor: OISHI TOMOJI
IPC: G02B5/22
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a high contrast and high precision surface treating film excellent in strength by incorporating an organic dye into a surface treating film and providing an absorption peak in a specified wavelength range. SOLUTION: A film can be made achromatic with a burgundy dye and a green dye by using an organic dye obtained by combining a quinacridone dye and a naphthalocyanine dye because the burgundy quinacridone dye having its absorption peak in the range of 550-600 nm and the naphthalocyanine dye having its absorption peak in the range of 650-700 nm have complementary colors. Since a film containing the two-component dye has no absorption peak in the luminescence regions of red and blue phosphors, color purity and contrast are enhanced. The strength of the film is enhanced because the amount of the dye contained in the film is small.

Abstract: PURPOSE: To stop motor driving parts when an object comes into collision with a device for detecting collision by detecting the change of a fluid pressure caused by the deformation of a bag which is attached to the device and has an internal chamber housing such a fluid as the air. CONSTITUTION: A collision sensor 12 attached to the end of an image receiving device 14 is provided with a toroidal air bag 30 and a circular flange 32 which is fitted to the cylindrical housing of the device 14.

Title: Magnetic disk device
Inventor: SEGA MASAHIKO
IPC: G11B21/02
Filed: 1993-03-18
Abstract: PURPOSE:To prevent the positioning accuracy of a head from being lowered by vibrations and impulse for a disk which is caused by reactive force generated in the case of head seek. CONSTITUTION:The member on the side of a housing 11 of an actuator is guided so as to be moved in the same direction as a mechanism 21 for supporting a head assembly, and an air spring 30 and a spring are arranged at a gap with the housing. The reactive force generated by the head seek is escaped by a guiding mechanism 22 on the housing side member of the actuator, and the generation of spindle vibrations is suppressed by preventing the reactive force from being propagated to the spindle. The air spring is provided with diaphragm and suppresses the amplitude small by attenuating the reactive force to resonate the housing side member of the actuator even when the reactive force is generated. The spring between the housing side member of the actuator and the housing regulates a relative position with a peripheral member including the supporting mechanism side member of the actuator.

Filed: 1979-05-11
Abstract: PURPOSE:To improve the performance of the unit by a method wherein at the part directly under a Schottky diode, a buried collector layer is made to rise to the surface to lower the serial resistance of the built-in Schottky diode. CONSTITUTION:When a buried layer 8 is made in a P-type substrate 3, the surface impurities density in the buried layer 81 directly under Schottky diode SBD 1 is made higher than the buiried layer part 82 under the base layer 6 and the collector N-layer 4 is epitaxially formed. At this time, the buried part 82 largely rises than the part 81 thus enabling to lower the resistance R4, value without any harm. Directly under the P-type base layer 6, the buried layer 82 is checked to rise so that the depletion layer of the base collector junction fully expands with no lowered breakdown voltage. Through said constitution the serial resistance reduces so that the suspending capacity and joining capacity are speedily charge-and-discharged to operate SBD more effectively.

Title: Fire sensing device for large space
Inventor: SETO KATSUMI
IPC: A62C31/00
Filed: 1990-03-09
Abstract: PURPOSE:To securely and speedily detect a fire by generating a fire signal when smoke sensors which are provided in two high and lower cross sections generate smoke sensing output at the same time. CONSTITUTION:The photoelectric separation type smoke sensors 2 are arranged in the two high and lower cross sections of a large-capacity space so that plural projection and photodetection axes 3 are spread. Then the presence of smoke is detected when light beams projecting between the projector photodetectors 2a and 2b of the smoke sensors attenuate by more than a specific level between in the two high and lower cross sections and a fire is sensed when both the smoke sensors generate their outputs at the same time. Consequently, even if a stage suspended body moves up or down and the smoke sensor in one cross section detects it, simultaneous detection in the two high and low cross sections is not performed and no misdetection is caused. Further, the fire detection is possible even when the smoke does not reach the ceiling surface. Consequently, a fire can speedily be sensed even in a large-capacity space whose ceiling is high.

Title: Driving method of signal output stage in charge coupling element
Inventor: SATOU MAKI
IPC: H04N5/335
Filed: 1983-04-05
Abstract: PURPOSE:To expand the dynamic range of a signal output stage by operating an output gate electrode and a precharge gate electrode by means of a driving clock opposite in phase to each other so as to cancel each coupling capacitance of the precharge gate electrode and the output gate electrode. CONSTITUTION:The waveform of a gate voltage VOG impressed to the output gate electrode 8 of a signal output stage 9 of the charge coupling element and of a precharge voltage VPG impressed to the precharge gate electrode 6 is shown in Figure. The precharge voltage VPG is synchronized with a transfer clock phiCK of the charge transfer stage 3. Further, the gate voltage VOG impressed to the output gate electrode 8 is given with a voltage change in the opposite phase to the precharge voltage VPG. That is, in the method of this invention, the precharge gate electrode 6 of a signal output stage 9 of the charge coupling element and the output gate electrode 8 are operated by the driving clock in the opposite phase. Thus, the effect on an output signal due to the coupling capacitance C1 between the precharge gate electrode 6 and an N<+> region 5 is corrected by a coupling capacitance C2 between the output gate electrode 8 and the N<+> region 5.
