Title: Production of polyester
Inventor: UEDA TOMOAKI
IPC: C08G63/78
Filed: 1983-05-16
Abstract: PURPOSE:To obtain a polyester which has excellent moldability and gives moldings having excellent slipperiness, etc., by adding a phosphorus compd. and an alkali metal compd. after the completion of an esterification reaction, then adding an alkaline earth metal compd. and carrying out a polycondensation reaction. CONSTITUTION:Terephthalic acid or its ester-forming derivative, such as dimethyl terephthalate, and ethylene glycol are subjected to an esterification reaction or an ester exchange reaction in the presence of a catalyst. After the substantial completion of the reaction, a phosphorus compd. such as phosphoric acid or trimethyl phosphate and an alkali metal compd. such as lithium acetate or sodium propionate are added, and then an alkaline earth metal compd. such as calcium acatate or barium propionate is added. A polycondensation reaction is then carried out, thus obtaining a polyester mainly composed of an ethylene terephthalate unit as the main structural unit and contg. a large quantity of fine particles.

Title: Tape cassette
Inventor: KONDO YOSHIO
IPC: G11B25/06
Filed: 1990-03-30
Abstract: PURPOSE:To miniaturize a recording and reproducing device by moving a tape reel to the rear part of a cassette housing in parallel at the time of use. CONSTITUTION:A recessed space formed in front of a reel moving member 10 is a mouse part 14 into which a head drum, etc., is inserted for recording or reproduction. Namely, the reel moving member 10 is guided and moved along parallel guide walls 13a and 13b of a lower half 3 and tape reels 4 and 5 are moved forward and backward in parallel to vary the size of the mouse part 14. Thus, both tape reels 4 and 5 are so structured as to move forward and backward in parallel, so reel shaft insertion holes 3a and 3b of the lower half 3 are formed as long holes which are long in the front-rear direction. The space in the cassette housing is therefore utilized effectively to make the mouse part 14 larger. Consequently, the recording and reproducing device is miniaturized.

Title: Retransmission control system for abnormal data
Inventor: OZAKI MIDORI
IPC: G06F13/00
Filed: 1992-04-07
Abstract: PURPOSE:To avoid re-transmission of useless data by informing transmission data via a sender side when a receiver side detects abnormal data and allowing the user to discriminate the abnormal data and the necessity of re-transmission. CONSTITUTION:Transmission data received through a LAN line 6 are sent from a data reception section 1 to a reception data check section 2, in which the presence of a returned identifier is checked. When the returned identifier is in existence, it is sent to a user processing section 5. When no returned identifier is in existence, whether or not fault data are in existence in the received data is checked and when no fault data are in existence the data are sent to the user processing section 5. When the abnormal data are in existence, the data are sent to a reception data return section 3. The return section 3 adds the returned identifier to the data and sends the resulting data to a data transmission section 4. The data return section 4 returns the received data to the destination via the line 6. Then the user processing section 5 allows the user to discriminate the propriety of the re-transmission of the returned data. When the re-transmission is required, the processing section 5 implements error correction and sends the result to the return section 3.

Title: Deflection control type ink jet recorder
Inventor: HORIIE MASANORI
IPC: B41J2/175
Filed: 1982-05-19
Abstract: PURPOSE:To provide the titled recorder capable of eliminating affects of satellite droplets on recording without reducing recording speed, wherein the amplitude of a vibration in such as direction as to lower ink pressure is set to be larger than that of a vibration in such a direction as to raise the ink pressure. CONSTITUTION:An exciting voltage generator 19 is constituted of a sine wave converting circuit 19a, a half-wave rectifying and adding circuit 19b and an amplifying circuit 19c. The circuit 19a eliminates harmonic components of an input signal, while the circuit 19b adds the input signal and a half-wave rectified signal thereof to each other. Accordingly, the change in the ink pressure can be enlarged in such as direction as to lower the pressure, and a large velocity change is obtained at a position in proximity to a part of the ink jetted when the ink pressure is minimum, resulting in that the ink is easily broken and the dropletization is stabilized.

Title: Oil hydraulic multi-lief clutch
Inventor: OOSONO KOUHEI
IPC: F16D48/02
Filed: 1983-05-14
Abstract: PURPOSE:To relieve the counter-load by sensing generation of drive torque from the rear wheel side through dislocation of the driven gear from the clutch outer, and by decompressing the oil pressure contributing the power transmission. CONSTITUTION:A rapid deceleration applies counter-load from the road surface to the rear wheels, and transmission of this counter-load to the clutch causes dislocation of the driven gear 24 from the clutch outer 22, and now a slant surface 56a formed at a web part 24a of the driven gear 24 will push out a cam pin 53 against the action of a push spring 55. A support spring 50 receives the pushing force through an operating piece 54, and a push pin 51 pushes open a reed valve 49 to cause leakage of the working oil contained in an oil pressure chamber 29 from a leak hole 47. Thus the torque capacity of the clutch is reduced to serve relief of the impact force when a counter-load is applied.
