Title: Offset printing machine
IPC: B41F7/10
Filed: 1991-08-22
Abstract: A cylinder setting mechanism for a single or multi-color offset printing device in which a blanket cylinder moves eccentrically about a first pivot point to make contact with a master cylinder so that it can be inked and then subsequently moved eccentrically about a second pivot point to make contact with the impression cylinder to transfer the image to paper. The invention enables the first and second pivot points to be adjusted to compensate for wear, plate thickness, and paper stock. In addition, a stop is provided to ensure that there is a predetermined contact pressure between the surfaces of the blanket cylinder and the master cylinder. The stop is automatically adjusted when the toggle is adjusted for a different thickness plate so that the desired offset printing pressure between the master and blanket cylinder surfaces is held at the optimum level.

Title: Duplexed clock signal generator
Inventor: TAKAHASHI SETSUO
IPC: H03L7/00
Filed: 1986-01-22
Abstract: PURPOSE:To avoid the omission of clock pulses in a system switching mode by using two signal source and using the selected signal source output clock to actuate two phase synchronizing oscillation circuits. CONSTITUTION:Selection indicating circuits 107 and 108 inform system selecting information to each other so that both clock switch circuits 103 and 104 select the outputs of the same signal sources 101 and 102. When the source 101 has a fault to cause an abnormal state where the output clock is cut off, both circuits 107 and 108 detect said abnormal state and output the switching signals to clock switching circuits 103 and 104. Both phase synchronizing oscillation circuits 105 and 106 absorb gradually the difference in phase between the input and output clocks and are finally synchronous with the A and B point clock signals II and III which are supplied from the source 102. Thus it is possible to avoid the ommision of pulses that are caused in a conventional clock signal source switching mode and then to absorb a large variation due to the operation of a processor.

Title: Shaft seal structure for centrifugal compressor
Inventor: SAKAENO TAKASHI
IPC: F04D29/10
Filed: 1994-02-01
Abstract: PURPOSE:To reduce incurring of a leakage loss by a method wherein fins are arranged on the shaft side and both an annular curved surface formed of a comparatively soft material and a discontinuous curved surface are formed on the static body side, in a labyrinth type shaft seal arranged at an extending-through part extending through a shaft and the static body of which a centrifugal compressor consists. CONSTITUTION:A member 3 formed of a comparatively soft material is supported facing a fin 2, arranged as a part of a rotary shaft 1, in structure wherein the member is adhered to a static body 4. A gap between the fin 2 and the member 3 is set such a manner that the fin 2 and the member 3 are brought into a slight contact with each other taking stretch of the centrifugal force of the rotary body occasioned by operation and the operation locus of the shaft into consideration. Meanwhile, since a differential pressure is also exerted on the two ends of the member 3, a support force higher than a shaft force by which the member 3 is forcibly moved in an axial direction is exerted between the static plate 4 and the member. The member 3 formed of a soft material is positioned in the recessed part of the static body 4, where occasion demands and this constitution copes with a comparatively high differential pressure.

Title: Treatment of chlorinated hydrocarbon solvent
Inventor: HASEGAWA YUKINORI
IPC: C07C21/00
Filed: 1983-01-27
Abstract: PURPOSE:To remove acid from fresh, used or regenerated and recovered chlorinated hydrocarbon solvent, rapidly without using water, by adding an aliphatic aimne to the solvent, and to protect the apparatus from corrosion by the addition of the excess aliphatic amine. CONSTITUTION:The acid existing in a chlorinated hydrocarbon solvent (e.g. methyl chloride, chloroform, etc.) is removed by adding an aliphatic amine to the solvent. The aliphatic amine may be gaseous, liquid or solid at normal temperature; however, it has referably a boiling point of 40-120 deg.C. The addition of the alphatic amine has no influence to the stabilizer such as 1,4-dioxane, isobutyl alcohol, nitromethane, etc. When the amine is used in excess to make the solvent alkaline, the corrosionproofing effect is developed, and accordingly, the amine can be added to the fresh solvent. As an alternative method, the aliphatic amine is attached to part of the solvent recovery apparatus, i.e. pipings, particles of the adsorbent, etc., and made to contact with the recovered solvent.
