Abstract: PURPOSE: To provide a one-touch opening and closing tank cap which is superior in the operation sense and operability, is small in an operating space, and is advantageous in a formative design and layout. CONSTITUTION: In a tank cap 1, a radial move of a pair of levers 4, 4 urged outwardly radially is changed to a rotary movement of a rotor 3, and a pair of lock detents 10, 10 urged outwardly of radially are retracted radially by the rotary movement of the rotor 3. There is provided a gasket plate 13 which can move freely in an axial direction of the rotor 3, and is urged in a direction of the lock detents, and the gasket plate 13 is meshed with the lock detents 10, 10 in a retracting state, and also when the gasket plate 13 is moved to a direction of the counter-lock detent, the gasket plate 13 is structured so as to unmesh from the lock detents 10, 10. Then, the tank cap 1 is quickly readily detached only by its own pressing operation and pressing operation of the levers 4, 4.

Title: Decoding device
Inventor: ISHIKAWA TAKASHI
IPC: H04N19/182
Filed: 1989-06-01
Abstract: PURPOSE:To reduce a granular noise in a flat part by detecting the generation of a gradient overload and whether it is in an edge terminal part or not with regard to each decoding value, and replacing the decoding value in which a gradient load is generated with the decoding value in the edge terminal part in accordance with an output. CONSTITUTION:An encoding code Yi inputted from a terminal 10 is applied to reverse quantizers A12, B14 and a range end detecting circuit 28, and from a switch 20, a decoding value Xi is obtained. A comparing circuit 32 compares the decoding value Xi outputted from the switch 20, and a predictor Xi outputted from a D-type FF 26, that is, a decoding value Xi-1 of the previous picture element, and outputs a positive/negative code Mi for showing whether a difference value is positive or negative. This code Mi is supplied to a D-type FF 34 and a gradient overload detecting circuit 36. The D-type FF 34 supplies the positive/negative code to the circuit 36 by the next clock cycle. The circuit 36 decides that a gradient overload is generated in the decoding value Xi-1 only in the case a range end deciding signal Li-1 is 'H', and also, the difference value positive/negative code Mi and a difference value positive/ negative code Mi-1 immediately before it coincide with each other, and replaces the decoding value in which the gradient overload with the decoding value of an edge terminal part.

Title: Film unit with lens
Inventor: KAMATA KAZUO
IPC: G03B17/04
Filed: 1992-06-01
Abstract: PURPOSE:To disable a film unit with a lens to be used again by using a film on a market or the like and to prevent misphotographing caused by the reloading of the film or the use of the film unit over a recycling limit by constituting the number of teeth of a sprocket by the specified number. CONSTITUTION:The follower sprocket 34 is constituted of nine teeth by increasing the number of teeth by one in comparison with a sprocket (the number of teeth is eight) for a normal 135 type film. In accordance with it, the pitch of the perforations 23a of the film 23 is formed smaller than that of the 135 type film. Since the perforations 23a of the film 23 are formed at the special pitch, the film 23 is dedicated for this film unit. Therefore, even when the general 135 type film on a market is loaded, it is not engaged because the teeth 34a of the sprocket 34 are not aligned with the pitch of the perforations 23a.

IPC: H03K19/0185
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption without increasing the signal transmission time by operating an inverter circuit by the power voltage that is lower than the power voltage which operates a delay circuit and a buffer circuit. SOLUTION: A capacitor 6 uses the gate capacitance of a MISFET, and a diode 3 prevents the reverse current in an active mode of a level shift circuit and uses a PN junction diode that can be constructed when the MISFET is produced. A delay circuit 4 contains an even number of C-MIS inverter circuits having comparatively high output impedances which are concatenated together. The circuit 4 and a buffer circuit 5 are operated by the 1st power voltage of -3.3V, and an inverter circuit 7 is operated by the 2nd power voltage of -5V, i.e., VPV that is equal to the power voltage level of an external logic circuit connected to the output side of the level shift circuit. Thus, it's possible to reduce the power consumption while keeping a short signal transmission time by securing the operations of component circuits by the negative power voltage.

Title: Drain water processing device for air conditioner
Inventor: HAMADA SHINGO
IPC: F24F11/02
Filed: 1987-06-08
Abstract: PURPOSE:To prevent the stagnation of atomized water by providing an outdoor side fan which can cause the air flow to an outdoor heat exchanger to be reversed for cooling and heating, and a separator wall which extends upwardly from around the outlet of an atomizer. CONSTITUTION:During the cooling mode operation, the condensate from an indoor heat exchanger 3 is gradually collected in an indoor drain pan 8 and further in a drain pan 4. When the surface of water 13 rises up to a water level sensing means 16, the ultrasonic vibrator 22 of an atomizer 5 is started to discharge the water mist out of an outlet 6, which mist is then mixed with the outside air by an air flow caused by an outdoor side fan 12 and discharged to the outside through an outdoor heat exchanger 11 without stagnating. During the heating mode operation, on the other hand, the frost melt from the outdoor heat exchanger 11 due to the defrosting operation is collected in the drain pan 4. Because of a separator wall 17, the outlet 6 is not submerged in the water, and the ultrasonic vibrator 22 is started by the sensing action of the sensing means 16. As the rotation of the outdoor side fan 12 is reversed, the mist of water 13 is discharged through the outdoor heat exchanger 11 without stagnating. Therefore, the drain water is processed properly.
