Title: Scroll compressor
Inventor: SUZUKI SHUNJI
IPC: F04C18/02
Filed: 1986-09-20
Abstract: PURPOSE:To prevent contact of a lap and a counter part mirror board due to thermal expansion when a compressor is operating, by forming the mirror board of scroll from material having low coefficient of thermal expansion at the side for forming the lap while from material having high coefficient of thermal expansion at the rear face section. CONSTITUTION:In mirror boards 3, 12, respective sections 3A, 12A for forming laps are formed of material having low coefficient of thermal expansion while the rear face sections 3B, 12B are formed of material having high coefficient of thermal expansion. When a compressor is functioned, the high pressure central sections of respective scrolls is brought into high temperature condition to exhibit considerable thermal expansion, so as to deform respective mirror boards 3, 12 thermally such that the central sections thereof are separated each other. Consequently, even when respective laps 4, 14 are expanded by the compressor and extended axially, the extension is cancelled by the deformation of the mirror boards 3, 12 in the separating direction, thereby the gap between respective lap sections 14, 14 and the mirror boards 12, 3 is maintained constant irrespective of the temperature condition resulting in prevention of contact between the lap and the counter part mirror board.

Title: Constitution method for adaptive equalizer using neural network and viterbi decoder
Inventor: IWASAKI KEN
IPC: H03M13/23
Filed: 1993-08-17
Abstract: PURPOSE:To perform highly efficient high quality digital data transmission even under a weak propagation environment by combining a neural network and a viterbi decoder. CONSTITUTION:Reception demodulation signals pass through the forward direction calculation part 2-1 of the neural network 2 and are then inputted to the viterbi decoder 3. The output of the decoder 3 becomes decoded output and also the input of an encoder 4 and encoded again. The output of the encoder 4 becomes a reference signal for weight adjustment. In the meantime, a demodulation output value is supplied with time delay corresponding to the time delay of the decoder 3 by a delay line with a tap or a shift register 1 and becomes the input of the forward direction calculation part 2-2 of the network 2. A difference between the output of the calculator 2-2 and the decoder 4 is obtained and a differential signal is obtained. A weight is adjusted in a reverse direction calculation part 2-3 by the differential signal and signals reaching the viterbi decoder are calculated in the forward direction calculation part 2-1 by using the weight. The series of the operations is repeated.

Title: Removable disk cartridge
Inventor: MAMIYA TOSHIO
IPC: G11B23/033
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To eliminate a complicated mechanism to prevent erroneous loading by forming the end part side of a disc cartridge as a curving surface and then opening or closing the aperture by sliding the shutter along the curving surface. SOLUTION: If a disc cartridge 1 is loaded erroneously with a reversed front surface, the longer side surface aperture of the disk cartridge 1 is located at the right side, but the side surface 1c collides with a stopper member 48 and can no longer be loaded any more before the disc cartridge 1 is totally loaded. Moreover, since the disk cartridge 1 does not come in contact with a head 50 of the actuator 49 in standby, the head 50 is not broken by the erroneous loading either.

Title: Extension pipe for vacuum cleaner
Inventor: DOI KENICHIRO
IPC: A47L9/24
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To prevent dust or the like from being deposited, and improve operability by providing an operation body for moving a constraint element within an inner pipe in such a state as coupled to a recess, engaging a spring with one end of a holder, and forming a slope on the other end thereof, while one end of the operation body being supported and the other end thereof kept in contact with the slope of the holder. SOLUTION: A holder 8 is pressed to an operation body 10, due to the force of a spring 9. Consequently the operation body 10 turns and the end thereof is pushed up along the slope 8a of the holder 8. Also, the upper end 10b of the operation body 10 is held in such a state as projected above a cylinder cover 11. When the operation body 10 is pushed down, the end thereof goes down on the slope 8a of the holder 8, thereby causing the holder 8 to retreat against the force of the spring 9. The operation body 10 operates like a pushbutton. Thus, the holder 8 moves in the condition where fingers are released from the operation body 10, thereby causing the pressing surface 8c of the holder 8 to close the opening 6a of a cylindrical body 6 and pressing a constraint element 7 to the bottom of the recess 2a of the inner pipe 2.  On the other hand, the constraint element 7 is made free, when the operation body 10 is pushed by fingers and the holder 8 is made to retreat.

Abstract: PURPOSE:To enhance preservability, a color forming property and the stability of a developed color image, by using a specific compound as an electron donating leuco dye. CONSTITUTION:In recording material utilizing color development utilizing the contact of an electron donating leuco dye and an electron acceptive compound, a compound represented by general formula (I) (wherein R1-R10 are a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a substituted amino group or an aryl group, and R7 and R8 and R9 and R10 may bond to each other to form a ring. R is a group having a 1-12C addition polymerizable group) is used as the leuco dye. The electron donating leuco dye is a colorless-light-colored crystal and has high solubility to an org. solvent and rapidly forms a blue color upon the contact with the electron acceptive compound. The developed color dye is extremely stable and generates almost no discoloration and fading by long-time light irradiation, heating and humidification and, therefore, extremely advantageous from the viewpoint of long-term preservation of recording. Further, the stability of the color forming agent is also excellent and, further, by polymerizing said compound if necessary, new function can be imparted. Therefore, said compound has a capacity near to an ideal one as the color forming agent of a recording material such as pressure-sensitive paper, thermal paper or photosensitive pressure-sensitive paper.

Abstract: PURPOSE:To form a uniform water film on a plate cylinder, by generating ionized fine water particles from ionized water through an ultrasonic transmitter so as to make the polarity thereof opposite to that of a printing plate and adhering said ionized fine water particles to the printing plate. CONSTITUTION:Ionized water is prepared by using a water electrolytic apparatus and cationized water is poured in an ionized water tank 14 in such a case that a printing plate 11 is made of aluminum. Ionized fine water particles 16 are continuously generated from the ionized water by an ultrasonic wave generator 15 and injected from the slit of a slit duct 21 by a blower 17 through a duct 18 and a distributor 19 while the flow rate thereof is controlled by a flow rate control valve 23 to bond damping water to the printing plate 11. In the process before the ionized water is injected, all of metal parts are coated with plastic. This coating treatment prevents the neutralization of the ionized water. When the printing plate 11 composed of a polymer material is used, the fine particles of anionized water can be uniformly bonded to the printing plate 11.
