IPC: C07D317/64
Filed: 1992-03-05
Abstract: PURPOSE:To produce the subject oudemansin exhibiting a strong antibacterial effect from a new quebrachitol derivative as the starting raw material through new intermediates. CONSTITUTION:The 3-4 bond of a quebrachitol derivative of formula I (R<1> is a divalent hydrocarbon group) is cut so as to form a linear compound and the terminal OH groups are each protected by an acyl group R<3> to obtain a compound of formula II. The group R of the compound of formula II is eliminated so as to converted into an hydroxyl group and the C-C linkage bonded to the hydroxyl group is cut by oxidation. The resultant aldehyde is reduced to obtain a compound of formula III and the hydroxyl group of this compound is converted into a cyano group. The resultant compound of formula IV is deacylated and the obtained terminal alcohol is oxidized to an aldehyde. The resultant compound of formula V is converted into a compound of formula VI, e.g. by Wittig reaction. From this compound, the objective compound of formula VII (R<2> is phenyl, 4-methoxyphenyl or 3-methoxy-4- chlorophenyl) in which the partial structure composed of 9 to 10 positions corresponds to the three part structure composed of 5 to 6 positions of the compound of formula I can be obtained. The compounds of formulae II to IV and of formula VI are each a new substance.

IPC: G06F7/58
Filed: 1982-03-26
Abstract: PURPOSE:To generate long pseudo-random numbers having less deviation, by detecting the position of an element having variation due to radiation within a specific time. CONSTITUTION:Alpha rays 2 are entered into one bit of a 64,000-bit RAM3. When all bits of the RAM3 are set to ''0'' initially, only the bit where the alpha rays 2 are entered is in a ''1'' state. In one millisecond, about 9 bits are set to ''1'' at random. In every millisecond, a decoder 4 detect addresses of bits of the RAM3 set to ''1'' and those of bits which are still in a ''0'' state. On the basis of the output of the decoder 4, a logical circuit 5 set digit positions corresponding to the addresses of the ''1'' bits in binary notation among 64,000 digits to ''1''. Further, digit positions corresponding to the addresses of the bits which are still ''0'' are set to ''0''. Then, all the bits of the RAM are set to ''0'' again to generate a binary pseudo-random number string 6 consisting of 64,000 digits in every millisecond.

Title: Secondary channel system
Inventor: OCHIAI TAKANAO
IPC: H04L27/18
Filed: 1986-03-06
Abstract: PURPOSE:To always keep the speed of a secondary channel equal to frame synchronization by adding the secondary channel and an information bit of a frame synchronizing signal at a prescribed period in transmission of a signal of a MODEM to change the frame synchronizing signal. CONSTITUTION:One frame consists of data of a main channel (M-CH), data of S-CH using an error correction code and a frame bit in a MODEM of a multi-value PSK system constituting the secondary channel (S-CH) by a time division system. The frame synchronization is kept constant by changing the numbers of modulation bits per symbol and said frame bit number when the speed of the M-CH speed is changed to keep the speed of the S-CH constant. Thus, the bit number for a frame signal is varied in this way, the transmission speed of the S-CH is kept constant even when the transmission speed of the M-CH is changed. Since an error correction code is used for the S-CH, a characteristic having a fewer error rate than that of the M-CH is obtained.

Abstract: PURPOSE:To prevent the generation of a cold shut in a product by removing part of the inside surface side wall of an injection sleeve to an arc shape to provide groove-shaped relief parts to the positions averting the gate part at the height of a gate communicating with a cavity. CONSTITUTION:The relief parts 5 are provided in the direction perpendicular to the gate 2 in the position where the gate part is averted at the height of the gate on the lower side of the injection sleeve 4 provided to an upper die. The relief parts 5 are formed of the grooves 5a by removing the inside surface side wall of the sleeve 4 to the arc shape. The solidified layer formed on the wall of the injection sleeve 4 when pressurized packing is started upon pushing down of the top surface of a molten metal by an injection plunger tip does not slide downward as the solidified layer formed in the relief parts 5 acts as a stopper and therefore, the clogging of the gate 2 is obviated. The solidified layer formed in the relief parts 5 is strongest and the solidified layer formed on the wall of the injection sleeve 4 is bent inward and the intrusion of the solidified layer into the cavity is prevented until the packing is completed. The generation of defects such as cold shut in the product formed in the cavity is thus obviated.
