Title: Collection of l-quebrachytol from natural rubber sap
Inventor: UDAGAWA YOSHITAKA
IPC: C07C41/36
Filed: 1989-06-23
Abstract: PURPOSE: To obtain L-quebraohitol which can be a raw material for drugs and agrichemicals from natural rubber serosity by separating L-quebrachitol contained in natural rubber serum with methyl alcohol.  
     CONSTITUTION: L-Quebrachitol (monomethyl ether of L-inositol) contained in natural rubber serum is separated simply by using a 20-100 m liter of methyl alcohol per 100 g of concentrated natural rubber serum or preferably its dry solid and extracting preferably at -20-40°C to attempt the effective utilization of a natural rubber serum component which has been discarded so far as waste liquid and the mass production of L-quebrachitol. This method enables easier purification as compared with a method in which L-quebrachitol in natural rubber serum is acetylated and separated and gives high purity L-quebrachitol easily.

Title: Magnetic recorder
Inventor: NAKAGAWA TAKASHI
IPC: G11B15/18
Filed: 1978-12-28
Abstract: PURPOSE:To enable equal intervals of recording trace of the control signals before and after the pause without adjustment, by holding the tape at pause after rewinding it for a given length and using the output of the frequency generator provided at the capstan for the control signal. CONSTITUTION:At the pause, the pressing condition is held without detaching the pinch roller from the capstan 18, the capstan motor 17 is reversed and after the tape is rewound for a given length, it is stopped. The capstan motor 17 is provided with the frequency generator and the detection signal performs the constant drive of capstan motor and rotary phase servo. Thus, the rising time of the tape drive system at pause release can be covered with the tape rewinding to enable to obtain constant tape speed for the joint of recording. Further, since the output of the frequency generator is used as the control signal, the intervals of the recording trace of the control signal are not changed at the joints of the pause before and after. Accordingly, the intervals can be kept constant without adjustement. Thus, reproduced picture is made stable.

Abstract: PURPOSE:To initialize a RAM in a very short time by providing a means which selects all word lines of the RAM simultaneously and a means which gives data to all bit lines of the RAM simultaneously. CONSTITUTION:When a signal RESET is set to the high level ''1'', outputs of OR gates ORy0-ORyn go to ''1'' to select all word lines of RAM cells simultaneously. Since outputs of all OR gates ORx0-ORxn connected to bit lines go to ''1'' when the signal RESET is set to ''1'', ''1'' is written in all RAM cells simultaneously, and all RAM cells are initialized with initial value ''1''. In case that they are initialized with the low level ''0'', NOR gates are used as gates ORx0-ORxn, and signals of lines D0-Dn are inverted and are inputted to gates ORx0-ORxn.
