Title: Purification of acetonitrile containing hydrogen cyanide
Inventor: HIGUCHI TERUMASA
IPC: C07C253/00
Filed: 1979-03-28
Abstract: PURPOSE: To eliminate hydrogen cyanide from crude acetonitrile containing hydrogen cyanide, easily and almost completely, without decomposition of acetonitrile, by reacting the crude acetonitrile with a specific amount of an alkali and thereafter distilling in vacuum.  
     CONSTITUTION: Concentrated acetonitrile almost free from hydrogen cyanide is recovered in high yield, by reacting (A) crude acetonitrile containing hydrogen cyanide with (B) an alkali (e.g. NaOH or KOH) of the amount enough to convert free hydrogen cyanide in (A) to the alkali cyanide, and thereafter distilling the mixture in vacuum at 40W70°C. The alkali reacts only with free hydrogen cyanide and is inactive to cyanohydrin. The alkali treatment is performed preferably at 20W80°C.  
     EFFECT: Treatment steps are lessened and the cost of equipment and labor are decreased. High temperature is not necessary for the reaction.

Title: Hot rolled steel products having superior cold workability and toughness and their manufacture
Inventor: YANO KATSUAKI
IPC: C21D8/06
Filed: 1980-03-21
Abstract: PURPOSE: To manufacture hot rolled steel products having superior cold workability and toughness by properly controlling the steel heating temp. and the hot rolling temp. in a process of hot rolling carbon steel or alloy steel and the cooling rate after the hot rolling to give a spheroidized structure as hot rolled.  
     CONSTITUTION: Prior to hot rolling a billet of carbon steel contg. 0.03W1.20% C or alloy steel is heated to 650W850°C between the A 1  and A 3  transformation points to convert the structure into a mixed structure of ferrite and undercomposed carbide divided in the form of spheroids or rods or a mixed structure of austenite and undissolved carbide. The billet is then hot rolled at ≤950°C so that the carbide is not dissolved, and it is cooled at ≤40°C/min cooling rate in the about 750W650°C temp. range to obtain a finely spheroidized structure contg. finely dispersed ferrite and carbide. Thus, hot rolled steel products having superior cold workability and toughness are obtd.

Title: Film projector
Inventor: ITO MASAAKI
IPC: G06F17/30
Filed: 1987-02-19
Abstract: PURPOSE:To prevent a retrieval mark from exiting from a lighting area by moving a film breadthwise and detecting the retrieval mark provided to a side of a frame, and expanding the lighting area when deciding plural breadthwise frames. CONSTITUTION:Light from an exposure lamp 22 is controlled by a condenser lens 36 to illuminate the film F. An image imprinted on the film F is enlarged by a projection module 37, reflected by mirrors 38a-38e, and projected on a screen 1 in reader mode or recorded on recording paper P on a copying mechanism 68 in print mode. At this time, the film F is moved breadthwise so as to decide whether or not there are plural frames in the breadthwise direction of the film F; and a sensor detects retrieval marks provided to the sides of the frames of the film F to decide the number of the frames. At this time, the condenser lens 36 is moved as shown by an arrow G to expand the lighting area. Thus, the control is performed so as to expand the lighting area, so even when the film is moved breadthwise, no retrieval mark exits from the light area and information retrieval is accurately performed.

Filed: 1990-02-19
Abstract: PURPOSE:To enable operability and economy to be improved by setting a poten tial barrier layer which is formed on a crystal grain boundary to a tunnel barrier. CONSTITUTION:A grain boundary Josephson junction is produced by a polycrystal thin film with Ba1-XMXBiO3 (M:K, Rb, 0.22<X<0.5) having a simple perovskite structure. Thus, since a superconductive transfer temperature Tc exceeds 30K. the grain boundary Josephson junction appears at a temperature below 30K and a tunnel-type characteristic results even at a temperature below 20K due to high potential failure, thus obtaining a grain boundary Josephson junction with a tunnel-type characteristic having a history in current-voltage characteristic even at a temperature 10K where a simple and economical refriger ator is developed.

Title: Visibility widener for vehicle
Inventor: ISHIDA MASAHIKO
IPC: B60N2/90
Filed: 1986-02-25
Abstract: PURPOSE:To make a visual range short of the left front enlargeable, by installing an actuator moving a driver's seat up and down and also an electrofluid pressure system driving this actuator, in case of a vehicle having a see-though window in the lower part of a left front door. CONSTITUTION:A vehicle is provided with a see-through window 18 in the lower part of a front door 16, while it is also provided with a visibility widener 10. As for operation of this device, when a steering handle is selected more than the specified angle at the time of the vehicle 12 being turned to the left, a selector switch 24 is operated. If so, an electrofluid pressure system 22 is driven and thereby an actuator 20 makes a driver's seat go upward. In consequence, a visual point of a driver comes high so that his visibility is directly widened. Thus, at the time of turning to the left, the visual range short of the left front is enlargeable yet wider and, what is more, the visual range due to a difference in physique of the driver is improvable.

Abstract: PURPOSE:To improve the strength of a product and its productivity by forming a recessed air-gap through pressure on a boundary projecting part of a pair of rim parts, and also, increasing the thickness quantity of the rim base part by the thickness quantity of the air-gap part. CONSTITUTION:A pair of rim parts 3a, 3b are formed in advance by slitting in the outside periphery of a web part 2 of a disk stock, and also, a recessed air-gap 7 is formed by pressing a generated boundary projecting part 5 in the axial direction of the web part. In this case, the thickness quantity of the recessed air-gap 7 is replaced with the thickness quantity of a base part 6 of a rum part 2, and an indentation of the base part 6 is varied to an R-shaped gently-sloping base part 6. Subsequently, a crest-shaped V-groove is formed on the outside peripheral surface of the rim parts 3a, 3b, and a multi-stage pulley is obtained. According to this method, the strength of the base part 6 is improved, therefore, the strength of a product is improved, and also, since it can be manufactured by only integrating such a simple manufacturing method as pressure, the productivity is improved.
