Abstract: PURPOSE: To obtain an antimicrobial agent Cefmetazole, etc. readily without using an unstable raw material, by cyanomethylating a novel cephem compound.  
     CONSTITUTION: A 7β-mercaptoacetamido-7α-methoxy-3-cephem compound of formula I (R 1  is a group which will not participate in the reaction; R 2  is carboxyl or protected carboxyl) is reacted with a novel compound of the formula NCCH 2 X (X is halogen, etc.) in the presence of a base, and the protecting group is removed when R 2  is an esterified carboxyl group to give a 7β-cyanomethylthioacetamido- 7α-methoxy-3-substituted-3-cephem-4-carboxylic acid of formula II. An unstable raw material such as cyanomethylthioacetyl halide need not be used. The novel compound of formula I is obtained by removing the protecting group R 3  from a compound of formula III (R 3  is a protecting group of the mercapto group) by the conventional method.

IPC: C09D7/12
Filed: 1980-04-21
Abstract: PURPOSE:To improve electromagnetic conversion characteristics and traveling stability by using the magnetic coating soln. prepd. through kneading and dispersing a part of a dispersant to finely divided magnetic powder, a binde and other necessary components, then controlling the viscosity of the mixture and further adding the remaining dispersant, and allowing the same to disperse under agitation. CONSTITUTION:A higher fatty acid of C 12-18 or lecitin is used as a dispersant for finely divided magnetic powder, and a part of this dispersant is added to a composition consisting of finely divided magnetic powder, a binder, a lubricant and other necessary components plus a solvent, thence the mixture is kneaded. Next, after the viscosity of the mixture is controlled, the remaining dispersant is added and the mixture is thoroughly kneaded, whereby the magnetic coating soln. is prepd. This coating soln. is coated on a substrate, whereby a magnetic layer is formed. The dispersion condition of the magnetic powder is better than that by addition of the entire dispersant at one time, and the electromagnetic conversion characteristics and traveling characteristics such as S/N ratio, sensitivity and others are improved, thus the superior magnetic tapes, magnetic discs, etc. are obtained.

Title: Flange back adjustment method for video camera using inner focus lens
Inventor: HIROTA KATSUAKI
IPC: G02B7/28
Filed: 1994-02-25
Abstract: PURPOSE:To reduce an adjustment time by detecting an apex position on a cam curve and estimating a position of an end point from a position of a variator before being reached to the end point so as to prevent the variator during adjustment from being in mechanical contact with the end. CONSTITUTION:An apex of a cam curve is detected and a variator 3 and a focus lens 5 are located to a position of the apex and a telescopic end and a wide end are specified based on the apex on the cam curve. Then the positions of the telescopic end and the wide end are estimated through calculation based on the position of the variator before reaching the telescopic end and the wide end. This estimate is implemented by using a ratio of a distance from a position of the variator 3 to one end point focused when the focus lens 5 is moved by a prescribed quantity from the apex on the cam curve obtained in advance to a distance from a position of the variator 3 to the other end point focused when the focus lens 5 is moved by a prescribed quantity from the apex on the cam curve obtained in advance. Thus, the mechanical contact of the variator 3 onto the end during adjustment is prevented.

Abstract: PROBLEM TO BE SOLVED: To restart the oscillation of an inverter securely even after the replacement of an electric light load and after turning ON/OFF of the load by a method wherein the voltage supply source of a starting circuit is obtained from the center connection point between two series-connected capacitors which are connected between both the terminals of an AC power supply and and between two resistors which are connected in parallel to the respective capacitors. SOLUTION: A timing at which a voltage whose phase is controlled by a dimmer 200 is applied between power supply lines and a timing at which the divided voltage is applied to a trigger device 111 are same. At that time, if a voltage applied to the trigger device 111 exceeds the breakover voltage of the trigger device 111, the trigger device 111 is quickly turned on and the charge stored in a capacitor 115 or 116 is made to flow into the base of a transistor 104 through a resistor 109 and an inverter starts oscillation. Therefore, when the inverter stops operation once and then restarts the operation, the trigger device is not kept in an ON-state and the operation can be restarted securely.
