Title: Ciphered digital transmitter
Inventor: EJIMA NAOKI
IPC: H04N7/16
Filed: 1984-10-09
Abstract: PURPOSE:To decode individually ciphering for a receiver by providing two kins of identification codes to a transmission and reception side device, using one code to apply individual control of the receiver and using the other code to cipher and decode a transmission key thereby applying sophisticated ciphering and applying the control of the transmission side. CONSTITUTION:Broadcast data is converted into a ciphering sentence at a ciphering means 6 at the transmission side 8 by using one of plural ciphering keys of a ciphering key generating means 2. On the other hand, all ciphering keys of the means 2 are ciphered by a ciphering means 5 by using data of an identification code storage means 4. The said ciphering sentence a transmission key, an address code of an output receiver of an identification code storage means 3, and data specifying concretely the key used in a ciphering key selection means 20 are inputted to a data transmission means 7 while they are related mutually on a data format or in time series. A receiver 19 divides the specific identification code, which is stored in identification code ROMs 13 and 14. When the data of the ROM13 and the received address code are coincident, the received transmission key is decoded under the data of the ROM14.

Title: Semiconductor memory device
Inventor: KASAI HIROYUKI
IPC: H01L27/108
Filed: 1991-08-23
Abstract: PURPOSE:To prevent a gate of a transistor from being affected by noise caused by variations of power supply voltage and prevent noise from being produced from the gate by providing a delay circuit between the gate and an electrode. CONSTITUTION:In the case where noise is produced on a power supply upon the power supply being turned on or upon variations of power supply voltage, power supply potential is supplied to gates of channel current bypassing transistors 31-34 through CR of a delay circuit 51, so that the noise is attenuated and the gates are prevented from being affected by the power supply noise. Further, building-up or building-down of the voltage is delayed and moderated through the delay circuit 51, so that the gate of the n channel current bypassing transistors 31-34 are gradually charged to prevent much of current to flow at a time and hence reduce the production of noise.

Title: Air conditioner
Inventor: OOTSUKA TADAYUKI
IPC: F24F1/00
Filed: 1985-09-27
Abstract: PURPOSE:To prevent mold from being generated at an air filter of an air conditioner owing to an accumulation of dust there and keep it clean by a method wherein anti-mold agent is immersed into the net of the air filter of the air conditioner. CONSTITUTION:An air filter 13 is composed of a frame 13a and a net 13b. The net 13a passes the air and removes dust. The net part 13b is formed of a synthetic resin immersed with anti-mold agent. Even if the removed dust is adhered to the net part 13b to start molding, the mold may not be generated because of an action of the anti-mold agent immersed in the net 13b. Even if the dust is washed away with water, the anti-mold agent is already immersed in the synthetic resin, so the agent hardly drops to loose its effect. If the anti- mold agent is of volatile type, the anti-mold agent may reach to every corner of a room together with the discharged air, providing an anti-mold action on the walls, floor and ceiling or the like.

Title: Air suction type sheet material adsorbing apparatus
Inventor: NISHIBORI TOSHIKI
IPC: B65H3/08
Filed: 1983-11-11
Abstract: PURPOSE:To adsorb sheet material reliably one by one, in a system for sucking the mounted sheet and adsorbing, by differentiating the suction forces at the opposite ends at the tip of sheet material. CONSTITUTION:The sunction force through a suction port 4a contacting with one edge at the side of the tip of uppermost sheet material P' is differentiated from the suction force through a suction port 4b contacting with the other edge. The sheet material P' is adsorbed from the side facting with the suction port 4a to the sheet material adsorbing section 3. Since the sheet member P' is curled from the corner section facing with the suction port 4a, gap S is formed between the uppermost sheet material P' and next sheet material P'' to feed in air. Consequently, only the uppermost sheet material P' can be adsorbed reliably.

SOLUTION: The optical element or the integrated optical element or an MIOC has a top face 12, a +Z face 14 and a -Z face 16. The element is formed of a crystal, such as lithium or niobic acid, having a high electron-optic coefft. The +Z crystal axis elongates outward from the +Z face and the Z-axis is the axis which crosses the same and at which the pyroelectric effect is exhibited for the purpose of directing the parts of the optical elements to be disclosed. The top face is orthogonal with the Z-axis. An input waveguide 18 on the top surface receives a light signal from an input port 20 and passes the signal via a waveguide network to an output waveguide 26 connected to an output port. Part of the +Z and -Z face are at least partly coated with a conductive coating material.  The conduction path couples the +Z and -Z face faces to prevent the development of a charge difference between the +Z face and -Z faces in consequence of the temp. change and pyroelectric effect of the optical element.

Title: Butterfly valve
Inventor: ISOYAMA MITSUNORI
IPC: F16K1/22
Filed: 1986-09-10
Abstract: PURPOSE:To reduce the bending moment applied to a valve stem and make the valve stem small in diameter by coupling the valve stem and a valve plug, tightly coupling the valve stem and the valve plug at both ends of the valve plug, and forming a gap between the valve stem and the valve plug at the center of the valve plug. CONSTITUTION:In the coupling section between a valve stem 4 and a valve plug 3, the valve stem 4 and the valve plug 3 are tightly coupled at both end sides of the valve plug 3 respectively. A gap S is formed between the valve stem 4 and the valve plug 3 at the center of the valve plug 3. Thereby, the loading point to the valve stem 4 is shifted to both end sides of the valve plug 3, e.g., the sides near valve stem bearing sections 6, 15. Accordingly, the bending moment itself applied to the valve stem 4 can be effectively mitigated. In addition, together with the improvement of the supporting strength of the valve stem at both end sections of the valve stem respectively due to bearings at multiple points, the valve stem can be made further small in diameter.
