Title: Preparation of dithionite
Inventor: ARAKAWA SATOSHI
IPC: C01B17/66
Filed: 1980-03-06
Abstract: PURPOSE: To reduce the energy required for distillation, by washing a mother liquor stuck to anhydrous dithionite crystals with an organic solvent, and dividing and collecting the expelled washings into one part for recovery through distillation and the other part for direct use.  
     CONSTITUTION: Crystals of anhydrous dithionite obtained by reacting a formic acid compound with an alkaline compound and sulfurous acid anhydride in water- organic solvent are filtered and separated from the mother liquor. The mother liquor stuck to the crystals is washed with an organic solvent, e.g. methanol or ethanol, and 20W60wt% based on the amount of the crystals washings first expelled are distilled to recover the organic solvent, and the washings expelled next are not distilled and directly reused as a synthetic reaction solvent for the dithionite.

Title: Balance weight device for machine tool
Inventor: ITANI HIKOTARO
IPC: B23B47/26
Filed: 1990-02-09
Abstract: PURPOSE:To absorb column falling vibration at the time of processing or moving a column by a damper for preventing effects on the work precision by providing the damper inside each balance weight of a horizontal or vertical motion member of the column. CONSTITUTION:When the whole body of a column 2 is vibrated, balance weight 21, 31 also vibrate, but each damper mass 2, 33 inside is prevented from vibrating because of inertial action. A relative displacement is generated between the damper mass 25, 33 and the balance weight 21, 31, the relative vibration is restricted by viscosity of viscous fluid 26, 34 such as silicone oil injected between both of them, and the vibration is further restricted by action of resilient bodies 24, 32 to coordinate the specific vibration number of the damper mass 25, 33 with the specific vibration number of the column 2. The resilient bodies 24, 32 are composed of rubber, a plate spring, etc., and the resilient bodies 24, 32 may be molded integrally with the viscous fluid 26, 34 of viscous and resilient material such as rubber.

Abstract: PURPOSE:To obtain a low-noise flat head type printer which is small and easy to handle with an easy exchange of the cover by housing an ink ribbon, a platen and a pinch roller on the cover side and a print head, driver and control circuit on the bode case side while the cover is mounted detachably on the body case. CONSTITUTION:A recording paper 65 is mounted on the body case 41 while a positioning mark being registered with an upper cover 58 left open. As a printing is performed, the printed paper 65 is discharged behind a printer passing through a clearance between hinge sections. The printing condition is visible at an opening of an upper base 53 through a transparent window 63. The body case 41 and the cover 58 are free to open or detach. Thus, everything can be done simply by exchanging the cover 58 even when adding other functions including coloring and attaching an inserter. With the cover 58 closed, printing can be done and printing sounds hardly leak outside thereby preventing the generation of noises.

Title: Drawn-ironed can body
Inventor: CHIISAKO MASASHI
IPC: B65D8/16
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To make it hard to generate defects during processing of a metal sheet coated on its both sides with polyester by a method wherein the birefringence of the polyester coating layer at a side wall part has a specified value, while the intrinsic viscosity thereof is at least a specified value. SOLUTION: In a drawn-ironed can body, birefringence of a polyester coating layer at the side wall part is 0.05-0.150. In the case where the value is below 0.050, the strength of the polyester coating layer becomes insufficient to incur defects easily and at the same time water-vapor permeability becomes lower to increase the possibility of corrosion of the base metal. In the case where the birefringence is above 0.150, the molecular orientation becomes too high, cracks occur easily in the direction of the height of the can. The intrinsic viscosity is at least 0.60 d1/g/. If the value is below that value, the toughness becomes insufficient, cracks occur easily when being impacted to the polyester coating layer at the can bottom where the molecular orientation is not processed.  In the standpoint of characteristics, the intrinsic viscosity has no upper limit, but it is desirable that the intrinsic viscosity is at most 1.00 d1/g in the standpoint of formability in the case the polyester coating layer is to be formed.

Abstract: PURPOSE:To secure an efficient self-bailer with a simple structure, by making an engine engaged means being attached to a ship's bottom function as the self-bailer by means of a high-speed water current to be jetted out of a propeller. CONSTITUTION:An engine 3 with a propeller is fitted in a lower recess 4 of the hull 1 from the underside, and both front and rear ends are attached to the hull 1 with an engaged member 9. In this engaged member 9 at the rear side, a lower surface is smoothly continued to an engine bottom part 33, and there is formed with an opening 97 to be opened to the rear of the ship bottom, whereby a scupper pipe 6 leading from an air intake 5 is interconnected thereto. Therefore, during navigation, a high-speed jet by the propeller flows along a lower surface 96 of the engaged member 9 from the lower surface 33, and since the opening 97 is decompressed, the water inside the scupper pipe 6 is drawn out by suction, thus drainage inside the air intake 5 is efficiently carried out. Thus, a structure of the small hydrovehicle is simplified and an efficient self-bailer can be realized.
