Title: Preparation of n-acylphenylalanine
Inventor: MITA RIYUUICHI
IPC: C07C233/47
Filed: 1984-04-10
Abstract: PURPOSE:To obtain the titled compound useful as a precursor for phenylalanines, by hydrolyzing a 2-substituted-4-(substituted)benzylidene-5-oxazolone with an alkali, preparing a reaction solution within a specific pH range, and catalytically reducing the solution. CONSTITUTION:A 2-substituted-4-(substituted)benzylidene-5-oxazolone of formula I (R<1> and R<2> each are independently H, halogen, etc.; R<3> is methyl or phenyl) is hydrolyzed with an alkali, and the pH of the resultant solution containing the hydrolysis product is adjusted to 5-9 with an acid. The adjusted solution is then catalytically reduced in the presence of a reduction catalyst, e.g. Pd or Pt based catalyst, to give the aimed compound of formula I . EFFECT:The time required for reduction can be more remarkably reduced than the reductive reaction in a strongly alkaline aqueous solution, and the catalyst recovered by filtration operation after the reduction can be directly circulated for use without deterioration in activity. The reductive reaction proceeds for almost the same length of time as in the use of a new catalyst.

Filed: 1982-04-26
Abstract: PURPOSE:To reduce the height, depth and hence size of a printer, by feeding a paper by a metallic paper presser and a paper-feeding roller, in a small-type printer. CONSTITUTION:A recording paper 17 inserted through a paper-inserting port 28 is guided by upper and lower guide members 15, 16, is passed between a printing head 11 and a platen 8, and is clamped by the paper-feeding roller 19 and the metallic paper presser 23. When the roller 19 is rotated in the direction of an arrow by a pulse motor 22 under this condition, the recording paper 17 is fed by an amount corresponding to the amount of rotation of the roller 19, since the paper 17 is pressed against the roller 19 by the paper presser 23. Accordingly, since it is unnecessary to provide any pinch-roller or any tractor, the printer is made to be smaller in size.

Title: Buffer circuit
Inventor: KOYA HIROSHI
IPC: H03K19/00
Filed: 1985-04-03
Abstract: PURPOSE:To suppress power loss and heat dissipation in a buffer circuit by connecting a delay gate giving a delay to a trailing or a leading of an input data signal to a gate of two transistors (TRs) of an inverter circuit whose output stage is of complementary type. CONSTITUTION:A delay circuit 5 generates a delay signal Dtau of an input data signal D. The signal Dtau together with the signal D is inputted to a 2-input AND circuit 6 and a 2-input OR circuit 7. The circuit 6 acts like the delay gate giving a delay of tau to the trailing of the signal D, the circuit 7 acts like the delay gate giving a delay by tau to the leading, and delay input data signals D1, D2 are outputted respectively as shown in figure. When the signal D falls down, a delay input PFETQ1 is conducted with a delay by tau, and when the signal D rises, an N FET Q2 is conducted with a delay by tau. Thus, both the FETs respond to the delay tau at the transient time when the level of the signal D changes and a period holding the nonconductive state is set, then no through- current is caused.

Title: Semiconductor memory
IPC: G11C29/00
Filed: 1992-03-27
Abstract: PURPOSE:To speed up column selection by using a stand-by memory cell and a stand-by bit line when a defect is generated in a memory cell or a bit line and controlling output drivers for normal and standby column selecting circuits. CONSTITUTION:When a column address 501 is defective, only one of standby column selecting lines 1101 is turned to an 'H' level by a standby column activating circuit 701 and a stand-by column is selected. In a normal column selecting circuit 302, a normal column activating signal 801 to be inputted to an output driver part is turned to the 'H' level and a normal column non- activating signal 901 is turned to the 'L' level almost simultaneously with the selection of the 1st NAND 1 by a normal column predecoding signal 602, so that the source of a PMOSFET 35 in a column selecting driver 3 becomes non-selective. Since a driver output is pulled down by the 2nd NMOSFET 37, all normal column selecting lines 1001 are turned to the 'L' level and the defective normal column is not selected. Thereby the multiselection of selection lines 1001, 1101 can be prevented and column selection can be accelerated.

Title: Coil-winding machine for armature
Inventor: KANAI KENJI
IPC: H02K15/09
Filed: 1989-03-23
Abstract: PURPOSE:To reduce the wear of a wire guide by making the velocity ratio between a fixed gear means and one intermediate gear means and the velocity ratio between a floating gear means and the other intermediate gear means equal to each other so that the wire guide can stop irrespective of the rotation of a spindle. CONSTITUTION:Serrated toothed belts 17a and 17b are respectively wound around and moved between intermediate pulleys 15a and 15b at both ends of a rotating shaft 14 and a fixed and floating pulleys 11 and 16 so that rotating forces can be transmitted at the same velocity ratio. When a spindle 3 is rotated, the paired intermediate pulleys 15a and 15b become planet gears and simultaneously roll on the peripheries of the pulleys 11 and 16. As a result, the rotating force of the spindle 3 against the supporting shaft 9 of a wire guide 7 is canceled and the wire guide 7 can be maintained in a relatively still state. Therefore, the wire guide 7 does not rotate together with the spindle 3 even when the spindle 3 is rotated at a high speed and the wear of the wire guide 7 can be prevented.
