Title: Fireproof window
Inventor: OKAMOTO KUNIO
IPC: E06B5/16
Filed: 1990-04-27
Abstract: PURPOSE: To prevent the breaking of double glazing window panes by holding a section between the double window panes under an airtight state and arranging a thermal fuse melted when air in an opening reaches a fixed temperature in a fire in an airtight manner. CONSTITUTION: Double glazing window panes 4 are composed of a pressure- resistant window pane 7 and a heat-resistant window pane 8 integrally connected so as to have a required opposed space through an annular spacer 5. The outer circumferential section of the spacer 5 is filled with fillers 16 and a section between both window panes 7, 8 is held under an airtight state, and a thermal fuse 9 is inserted into a through-hole 10 in an airtight manner. When air in the space 6 reaches a fixed high temperature in a fire, the fuse is melted, and air at high pressure and the high temperature is discharged to the outside from the through-hole 10. Accordingly, the possibility of the breaking of the double glazing window panes can be eliminated at the pressure of high-temperature air while a fire, smoke, a gas or the like is interrupted surely and the spread of the fire can be prevented.

Title: Output circuit of solid-state image pickup device

IPC: H04N5/335
Filed: 1985-05-29
Abstract: PURPOSE:To decrease a reset noise and a 1/f noise for improving S/N of an output signal and the picture quality by applying the inverse of G times amplification to an output signal from an output amplifier circuit and inputting the result to one terminal of a reset MOSFET through a feedback circuit. CONSTITUTION:The output signal of the output amplifier 4 is inputted to one terminal of a reset MOS FET 32 through an impedance 8 (ZL=RL) comprised of an external amplifier 5 having amplification factor -G times and a resistor RL. In this circuit, when the reset MOS FET 32 is turned on, a noise voltage generated between capacitors C0 is inputted in a form having the noise signal of opposite polarity through the voltage RL and the reset MOS FET 32. Thus, the noise generated between the capacitors C0 is cancelled by the noise signal inputted through the FET 32. On the other hand, the 1/f noise generated by a source follower MOS FET 31 is cancelled by the noise having opposite polarity inputted from a terminal 36 similarly as the noise of the reset MOS FET 32. Thus, the S/N of the output signal and the picture quality are improved remarkably.

Title: Magnetic recording thin film medium
Inventor: OOTANI YOSHIMITSU
IPC: G11B5/66
Filed: 1984-06-04
Abstract: PURPOSE:To enable easy preparation of a magnetic recording thin film medium which provides an increased recording density and output, by forming a parallel magnetization film of a thin iron oxide film, and a perpendicular magnetization film of an iron oxide film mixed with osmium. CONSTITUTION:To laminate a parallel magnetization film 2 and a perpendicular magnetization film 1 on a substrate 3, an iron oxide parallel magnetization film containing no Os is first formed, and an iron oxide film layer containing 3-6% Os is then deposited thereon. When this laminate is annealed in a magnetic field thereafter, the lower layer containing no Os remains as the parallel magnetization film 2 since no inductive anisotropy is given thereto, whereas the upper layer containing Os becomes a perpendicular magnetization film 1 which has a magnetic anisotropy in a direction perpendicular to the film plane. In consequence, when recording is effected on this medium, recorded bits are perpendicular in the upper layer, and the lower layer serves to concentrate the magnetic flux, so that the reproducing sensitivity and output are increased.

Abstract: PURPOSE:To heat the glass plates constituting the packages of liquid crystal devices to a soaking state in a short time and reduce energy consumption for heating by sandwiching the glass plates by soaking plates by way of elastic plates respectively on the front and back sides thereof at the time of heating said glass plates. CONSTITUTION:The packages of liquid crystal devices are formed with two sheets of glasses 1 which are opposedly held at a spacing of about 10mum with glass fibers as spacers. The glass plates 1 are then sandwiched by means of elastic plates 2 such as of silicone rubber or polyimide resin and are further sandwiched by soaking plates 3 of superior heat conductivity such as of Alor Cu. These are stacked in plural stages and are placed on a floow plate 3a and the pressure plate 3b in the top part is pressed by applying loads of 100-200kg with a pressing unit 5. When in this state these are put in a heating furnace and heated, the glass plates 1 are evenly heated through the elastic plates 2 on account of heat transfer from the soaking plates 3, thus they are heated to an even temperature over the entire part in a short time. Here, heat pipes or semiconductor heating elements may be used in place of Al or Cu plates for the soaking plates 3. When the heating elements are going to be used, there is no need for heating from the outside.

Abstract: PURPOSE:To ensure the small size unit, reduction in cost, and simplification in mechanism and assembling process, by turning the channel selection member for a given pitch accompanied with the depression of the center shaft and constituting that the buffer pin is alternatively buffered to the screw lever. CONSTITUTION:When the knob 8 of revolver type tuner is depressed, the buffer pin 21 is detached from the screw lever 4, and the drive member 25 is linked with the coupling 20' provided under the channel selection member 20 with equal pitch, and the member 20 is turned to the position in dotted lines with further depression. Further, when the buffering with the screw lever 4 is released, the member 20 is free and it turns with very light force, and the rotary angle of the member 20 turned with the member 25 is constant. On the other hand, since the screw lever 4 is positioned in agreement with the said rotary angle on the rotary locus of the pin 21, the pin 21 turns to the position linked with the next screw lever 4 sequentially every depression of the knob 8. Thus, different stations can be selected every depression of the knob 8 by storing the tuning frequency of desired station with the turning of the knob 8 to each screw lever 4.
