Title: Preparation of alpha-acetoxypropionic acid
Inventor: KITAMURA TAKANORI
IPC: C07C59/185
Filed: 1980-12-29
Abstract: PURPOSE: To prepare the titled compound useful as a raw material of lactic acid, etc., economically, in an industrial scale, by oxidizing α-acetoxypropionaldehyde with oxygen in liquid phase using a metal salt selected from copper salts, iron salts, and nickel salts, as catalyst.  
     CONSTITUTION: α-Acetoxypropionic acid is prepared in high rate of reaction and high selectivity, by oxidizing α-acetoxypropionaldehyde with oxygen gas or an oxygen-containing gas in liquid phase in the presence of a metal salt selected from copper salts, iron salts and nickel salts, esp. cupric carboxylate, ferrous carboxylate, ferric carboxylate, or nickel carboxylate. Since the accumulation of paracid in the reaction system in very little, the process is industrially advantageous. Acetic acid, propionic acid, methyl acetate, etc. can be used as the reaction solvent; however, it is preferable to use the objective α-acetoxypropionic acid as the solvent.

Title: Multilayer polyamide film
Inventor: BIWAKI HIDEKAZU
IPC: C08L23/08
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To make pinhole resistance improve by making the polyamide layer of a multilayer film from a composition of a crystalline polyamide, an amorphous polyamide, a and modified ethylene-vinyl acetate copolymer. SOLUTION: The polyamide layer of a multilayer film having at least two layers including the polyamide layer is made from a composition of a crystalline polyamide, an amorphous polyamide, and a modified ethylene-vinyl acetate copolymer. The polyamide layer is composed of 62-97wt.% crystalline polyamide, 28-1wt.% amorphous polyamide, and 10-2wt.% modified ethylene-vinyl acetate copolymer. When the content of the crystalline polyamide is below 62wt.%, the film tends to be hardened to reduce its pinhole resistance, and when it exceeds 97wt.%, the film tends to be broken to make film making difficult. When the content of the amorphous polyamide exceeds 28wt.%, the film tends to be hardened to reduce its pinhole resistance.

Title: Microprocessor
Inventor: TAKAHASHI HITOSHI
IPC: H01L21/66
Filed: 1988-07-28
Abstract: PURPOSE:To reduce the cost of a microprocessor by adding a test control circuit into an address decoding circuit and writing the contents of a bus into a port circuit at test control. CONSTITUTION:An address decoding circuit 4 contains a test control circuit 7 to control the test/normal actions of a port circuit 3. Then a test signal 8 is inputted to the circuit 7. The circuit 7 is controlled by the signal 8 at test control and therefore the contents of a bus 6 are written into the circuit 3. In other words, the functions are switched only at test for the circuit 3 kept under the control of a CPU 2 and a circuit 4 set between the CPU 2 and the circuit 3 in terms of the normal function among those test circuits of a microprocessor 1. Thus it is possible to eliminate the apparent margin defect due to the deterioration of the device speed caused by a low level of voltage and to avoid the misjudgement between the nondefect and defect products. In addition, the increase of the chip size can be minimized since a small number of test circuits are needed.

Denoting the setting voltage of an output power setting section 1 as E (DC value). Then an outputted current (I) from the operational amplifier 1 is expressed as equation I. Since the resistor 33b of the photoresistor element 33 changes as expressed in equation (II), the result is expressed in equation (III). In supplying a high frequency signal V1 from a high frequency oscillator 2, the output voltage V2 is expressed as equation (V) through the relation in equation (IV). Thus, in giving the output voltage V2 to the power amplifier 4, the high frequency power P outputted from the power amplifier 4 is expressed in equation (VI) and is proportional to the setting voltage E.
