Abstract: PURPOSE:To produce a glycidyl ether, in one step and high yield, by reacting an alcohol with an epihalohydrin in a binary phase system comprising a solid phase and an organic phase, i.e. solid alkali-alcohol-epihalohydrin, in the presence of a quaternary basic salt. CONSTITUTION:An alcohol (e.g. allyl alcohol) is made to react with an epihalohydrin in the presence of an alkali to obtain a glycidyl ether (e.g. allyl glycidyl ether). The reaction is carried out using a solid alkali [preferably NaOH or Ca(OH)2] in the copresence of a quaternary basic salt (e.g. tetramethylammonium chloride).

Title: Length measuring method
Inventor: MORITA MASAHIRO
IPC: G01D5/12
Filed: 1983-12-20
Abstract: PURPOSE:To measure length accurately by counting displacement and pressure variation between surfaces A and B owing to the horizontal movement of an index grating B on a scale grating A formed by recording N and S magnetic gradations. CONSTITUTION:Magnetic gradations are recorded on a scale grating A and an index grating B to form moire fringes to double length. Those A and B are put one over another at an angle theta of intersection, and when they move laterally so that magnetic poles N and N are superposed, the scales A and B repel each other, but when magnetic poles N and S are superposed, the scales A and B attracts each other. For the purpose, a sensor X such as a pressure sensor, strain gauge, load cell, magnetic sensor, and proximity sensor, is installed between the A and B, and then the sensor X generates an electric signal by the repellency and attraction owing to the movement of the magnetic scales A and B, so the signal is counted to take a measurement of length.

Title: Chucking device
Inventor: MIYAZAKI TAKESHI
IPC: B23Q3/06
Filed: 1983-12-19
Abstract: PURPOSE:To aim at simplification in chucking a work serving as a compact device being narrow in central axial width, by driving more than four chucking members equally in a central axial direction against energizing force in a centrifugal direction, while forcibly pressing the circumference of a barlike work material with uniformly distributed force. CONSTITUTION:A guide member is energized to the remotest position away from an upper plate 11 and a bottom plate 12 each by dint of a spring, and when a work is mounted on a lower guide part hereat and a piston shaft 8 is driven upward, a holding member 3 is also driven upward, coming nearer to a member 2, whereby energizing members 54 and 58 come into contact equally with chucking members 45 and 48. Next, when the member 3 is shifted upward, energizing members 51-58 is compressed by these chucking members 41-48, keeping regular intervals owing to compression reaction in these members 51-58 and compression force lying between both members 2 and 3, whereby they are set up on the same circumference of a circle. And, the member 3 is further driven upward, while these members 41-48 are driven in a central axial direction in a state of being situated on the circumference of a circle and forcibly press a circumferential surface of the work for caulking. For this reason, width in the central axial direction is able to be yet thinned and, what is more, chucking a long work is easily performable.

Filed: 1983-12-20
Abstract: PURPOSE:To obtain a uniform density of printing and to prolong the life of heating elements by varying the periods of application of voltage to a head to dispense energy through checking of the past conditions of recording in a history control section. CONSTITUTION:A printing control section 11 controls printing and running of paper and a head, and a history control section 12 controls the past conditions of printing. A pulse width control section 13 determines the optimum pulse width to be applied by consulting the present printing datum and the data in the history control section 12, driving a head 15 through a head driver 14. And whether the printing of this time is black or not for printing in one dot is checked and, if printing is not carried out, a head 21 is transferred. However, if the printing is to be carried out, a head Na is driven and advanced to the place where Nb was is not driven. If printing was not carried out, Nb is driven. Then, if printing was not carried out at the previous time but one also, Nb will be driven again. Thus, the pulse width control at three stages becomes feasible.

Title: Automatic switching system of multi-medium to station
Inventor: MURAI TAKESHI
IPC: H04M3/00
Filed: 1984-11-15
Abstract: PURPOSE:To attain transmission while other desired medium is connected without using a special control line by allowing the reception side to supervise always multi-medium information on a transmission line and transmitting a multi-frequency signal to an opposite station through a communication line when the transmission line is idle as a rule. CONSTITUTION:In depressing a medium selection key corresponding to a medium desired for connecting, a selection signal is transmitted to a controller 7. When the controller 7 receives a selection signal, a corresponding multi-frequency signal, e.g., a 2-frequency signal is generated and transmitted to a switch device 6. The switch device 6 transmits the 2-frequency signal to the controller 7 in the own station, and when the controller 7 recognizes the 2-frequency signal, a switching confirming signal is returned to the transmission station through the switch device 6 to change the connection to a media. Thus, the operating state is supervised normally and the reliability of the media switching is im proved with the means of the switching by the multi-frequency signal.
