Abstract: PURPOSE:To prevent a movable cylinder part from slipping off and facilitate installation of an intake and exhaust cylinder, by dividing the intake and exhaust cylinder into a movable cylinder part and a fixed cylinder part, thereby enabling the intake and exhaust cylinder to be extended and contracted, and providing a pawl and a slit at fitting parts of the movable cylinder part and the fixed cylinder part. CONSTITUTION:An intake passage is formed by a space 20, defined by movable outer and inner cylinders 2, 4 and fixed outer and inner cylinders 3, 5, an intake hole 15 and an intake pipe 21. An exhaust passage is formed by a space 22, defined by the movable inner cylinder 4 and the fixed inner cylinder 5, and an exhaust pipe 23. At the time of fitting an intake and exhaust cylinder 1 to a wall 24a, the fixed outer cylinder 3 comprises an interior flange 13 supported on both sides thereof by an outer peripheral rib 14a, and the flange 13 is fixed to a wall surface, whereby the cylinder 1 is securely fixed to the wall.

When the wall thickness is largest, a pawl 6 on the fixed outer cylinder 2 is fitted into a slit 7 in the movable outer cylinder 2, whereby the movable outer cylinder 2 is prevented from slipping off at the time of extension to a maximum extent. To fix the movable outer cylinder 2, an exterior flange 16 is inserted into the movable outer cylinder 2 from the exterior side, and a small screw 17 on a slip-off preventive ring 18 provided as one body with the flange 16 is tightened.

IPC: G01N27/62
Filed: 1984-01-27
Abstract: PURPOSE:To make it possible to positively detect the existence or non-existence of a flame by providing ceramic sensor at the tip end portion of a flame detecting electrode and/or at parts other than the tip end thereof. CONSTITUTION:A cylindrical ceramic body 6 made of a solid electrolyte having an oxygen ion conductivity at high temperatures, such as zirconia or the like, is mounted on the tip end of a heat-resisting and conductive pipe-shaped flame detecting electrode 1 made of a material such as an SiC heat-resisting metal or the like.

Title: Power switch
Inventor: SAKO SUKETSUGU
IPC: H01H50/32
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent a contact of a prescribed pole from being worn by providing movable contacts corresponding to fixed contacts corresponding to the number of phases of respective polyphase alternating currents and constituting the contact timing between the respective phases between the movable contacts and the fixed contacts in such a state as changing for every respective times. SOLUTION: When a cross bar 6 takes an oblique inclined attitude, a movable iron core 5 connected to the cross bar 6 takes the inclined attitude inclined in the same oblique direction. When a voltage is impressed to an excitation coil 3, a movable contact 108 in the right side is closed quicker than a movable contact 208 in the left side. A latchet 305 rotates a shaft 301 by 1/4 rotation for each switching operation so that the oblique inclined direction of the cross bar 6 alternately repeats rightward-declining and leftward-declining inclinations and therefore the closing timing between the right-side contact and the left-side contact is alternately changed. This action can prevent the prescribed pole from being worn, which is caused by that the prescribed one contacts is closed quicker than the others in closing.

Title: Image forming device
Inventor: SAKURAI MASATO
IPC: G03G13/08
Filed: 1984-01-28
Abstract: PURPOSE:To prevent the uneven image occurring in uneven electrostatic charge with a small sized device or an image having too much solid black having no gradation by using a hollow developer as a developer. CONSTITUTION:The toner as a developer is satisfactory as far as the toner is hollow. If the size of the space occupying in each individual toner, i.e., voids are too large, the toner is brittle to the external force during agitating in a developing device 4 and therefore the toner particles are likely to be broken prior to contribution to prescribed development. The voids of the toner are therefore up to about 60-70% at the highest. The uneven image occuring in uneven charging with the small sized device or formation of an image having too much solid black having no gradation is prevented by using such toner.

Abstract: PURPOSE:To send output data only to one specified output device by generating information enciphered corresponding to the specific terminal and a deciphering key signal when information is outputted to the terminal, and deciphering the enciphered information at the specified terminal and outputting a document. CONSTITUTION:A terminal 1 informs a node 27 of a DES system key K for communication by an open key enciphering system and sends a control signal A which is sent by a conventional enciphering system. A node 23 receiving the reports deciphers the DES system key by using an RSA system enciphering key 35 and sends it to a node 24. The transmitted key is decoded by using the RSA system decoding key to obtain the DES system key K. The node 23 confirms that the DES system key K arrives correctly and a code message obtained by enciphering a secret document by the DES system through a conventional enciphering device by using the key K is transmitted. The node 24 deciphers the code message by using the DES system key K obtained as mentioned above to obtain the secret document, which is transmitted to a terminal 22. A terminal 2 outputs the data to an output device 24.

Filed: 1991-01-14
Abstract: PURPOSE:To provide a low-pass filter device capable of performing the low-pass filtering of a large number of input signals selectively at high speed. CONSTITUTION:A multiplexer 34 which samples a large number of analog waveforms is provided with, and a series of analog sampling input voltages are fetched by the multiplexer. The output of the multiplexer is filtered by an active low-pass filter 20 including an input RC circuit network consisting of a serial connection resistance element and a branch capacitance element. The serial resistance element is short-circuited temporarily while the multiplexer 34 switches a state to sample a new analog signal, and after an output voltage is varied at high speed, an operation is returned to an ordinary low-pass filtering operation by releasing short-circuiting. Thereby, the switching of the multiplexer 34 can be performed without being limited by the through rate of the low-pass filter 20, which enables a channel to be switched at high speed.
