Title: Production of l-aspartic acid metal salt
Inventor: KITAJIMA MITSUHIRO
IPC: C07C227/18
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a highly transparent L-aspartic acid metal salt useful as e.g. an intermediate for medicines in high yield without deposit contamination and discoloration by reaction of ammonium L-aspartate with a metal hydroxide in an aqueous medium. SOLUTION: This L-aspartic acid metal salt is obtained by reaction of pref. 1mol of ammonium L-aspartate with pref. 0.8-3.5mol of a metal hydroxide such as sodium hydroxide in an aqueous medium in the presence of a chelating agent such as ethylenediaminetetraacetic acid. In preparing the ammonium L-aspartate by reaction between maleic acid or fumaric acid and ammonia, it is preferable that the ammonia is recovered and reused.

Title: Transistor inverter for threephase ac motor
Inventor: NOMURA TOSHIHIRO
IPC: H02M7/537
Filed: 1987-09-21
Abstract: PURPOSE:To reduce a snubber loss by directly connecting a snubber capacitor in parallel with a transistor switch(Tr), turning ON and OFF said Tr only once per 1 AC cycle and setting a sufficiently large time for turning OFF a pair of Trs of arms opposed to each other upward and downward so that said pair of Trs may return to the original condition. CONSTITUTION:Each of snubber capacitors 51-56 is directly connected in parallel with each of Trs 31-36. When Trs 31 and 32 are turned OFF and ON respectively, an electric current iu flows from a motor terminal U via the Tr 32 to the negative electrode of a power source 1. When the Tr 32 is turned OFF at this point of time, the current iu is received by a capacitor 52 and the half of said current, by a capacitor 51 a little later. As a result, the bath voltage of the Tr 32 rises with a gentle inclination determined by the electrostatic capacity of said capacitors 51, 52 and the current iu, and reaches a source voltage VDC after a charge and discharge time. When a set time for both of said pair of series transistors to be turned OFF is so set as to be longer than said charge and discharge time, it is possible to obtain a good transistor inverter.

Title: Ic card having data updating function
Inventor: MORIYAMA AKIKO
IPC: G06K19/073
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To omit a special card processing center that is necessary for updating a cipher key and to attain the safe updating of the key by registering the scheduled updating date of the key in a storage of an IC card and updating the key in the IC card after its scheduled updating date. SOLUTION: It is discriminated whether a key updating table is registered (S4). When the key updating table is registered, it is discriminated whether a 1st scheduled updating date of a cipher key has passed (S5). When the updating data has passed, it is discriminated whether a 1st cipher key is updated (S6). When the 1st key is not updated, the key is generated and updated (S7). When the 1st key is updated, it is discriminated whether another scheduled updating date of the cipher key is set (S8). When the scheduled updating date is set, it is discriminated whether the N-th scheduled updating date of the key has passed (S9). When the N-th scheduled updating date has passed, it is discriminated whether the N-th updating of the key is already carried out (S10). When the N-th updating of the key is not carried out, the key is generated and updated (S11).  This operation is repeated until a new scheduled updating date of the key is not set any more.

Title: Evaporator for non-azeotropic mixture
Inventor: SUMITOMO HIROYUKI
IPC: F22B1/16
Filed: 1990-09-05
Abstract: PURPOSE:To return non-evaporated liquid of high temperature into the supplied liquid of low temperature without generating bubbles by introducing non- evaporated liquid from a pump into a liquid supply line through a mixer, thereby effecting forced circulation in a plate type falling film evaporator. CONSTITUTION:A steam passage 22 and a heat source passage 23 are formed alternately through a heat transfer wall 21 in a plate type falling film evaporator 20. A fluid outlet 28 of a gas-liquid separator 26 is connected to a suction side of a pump 29. The discharge side of the pump 29 is connected to a mixer 30 provided at a liquid supply line 31. The mixer 30 promotes the turbulence of liquid passing through the inside, leading to irregular movement of liquid particles in a random manner. This causes the supplied liquid of low temperature and the non-evaporated liquid of high temperature to be mixed evenly and leads to uniform temperature change. Thus, evaporation of contents of low boiling point in the supplied liquid is suppressed. Even if bubbles are generated, they are absorbed in the cool liquid because of active turbulence heat transfer.

Title: Driving device of fine movement mechanism
Inventor: MASUI TOMOYUKI
IPC: H01L41/09
Filed: 1987-09-24
Abstract: PURPOSE:To easily control a speed by a method wherein an electric current flowing to a piezoelectric element actuator used to drive a fine movement mechanism is controlled in order to prevent a vibration from being caused and in order to prevent acceleration from being increased. CONSTITUTION:When an amount of an electric charge to be accumulated in a piezoelectric element is designated as Q and the proportionality constant is designated as alpha, a displacement value (x) of the piezoelectric element due to an exerted electric field is expressed by Equation (1). When both sides of Equation (1) is differentiated with respected to time t, Equation (3) is obtained. The left side of Equation (3) represents a displacement speed of a piezoelectric element actuator 1, and since the differentiated term on the left side of Equation (3) represents an electric current flowing in the piezoelectric element actuator 1, it can be seen that the displacement speed of the piezoelectric element actuator 1 is proportional to the electric current flowing in the piezoelectric element actuator 1. Therefore, when the electric current flowing in the piezoelectric element actuator 1 is controlled by using an electric current control device 3, the displacement speed of the piezoelectric element actuator 1 can be controlled, and the operation speed at an output part of a fine movement mechanism 2 can be controlled easily without generating vibrations and without increasing acceleration.
