Inventor: ONDA YASUKO
IPC: G01R31/26
Filed: 1990-11-28
Abstract: PURPOSE:To perform effective measurement with the minimum number of times of measurement in consideration of all possible stationary states of macro- cells in an IC under test by providing a computer section calculating the measurement period of a stationary power current. CONSTITUTION:A computer section 5 calculates the measurement period 4 containing two values 'H', 'L' of logical output values of macro-cells and minimizing the frequency of a test pattern 1 to be tested from output data 3 of the macro-cells in an IC under test corresponding to various periods of the test pattern 1, and a stationary power current is measured with a tester 2 at the above measurement period 4 of the test pattern 1. When the output data 3 of the macro-cells are as shown in the Figure, for example, the measurement period 4 is determined as the second and fourth periods by the computer section 5, and a defective lead can be detected 100% when the stationary power current of the tested IC is measured in the second and fourth periods of the test pattern 1.

Title: Graphic display device
Inventor: HARASHIMA TADAO
IPC: G06F17/50
Filed: 1989-12-25
Abstract: PURPOSE:To easily detect a logic error by displaying a signal having the undefined value and an enabled tristate buffer on a logic graphic in different colors. CONSTITUTION:A signal having the undefined value is obtained when a signal name having the U (undefined) logic value is retrieved out of a simulation result file. At the same time, an element having a TSBUF type is obtained with retrieval of a logic drawing file. Then a pin OC of the element is detected and the polarity (negative with inclusion of /B and positive with no inclusion of /B) of a relevant signal is obtained together with a signal name to be connected to the signal. Then the logic value of the signal is obtained out of the simulation result file, and an enable state is secured with the signal logic value set at 1 with the positive polarity of the pin and with the logic value set at 0 with the negative polarity respectively. Under such conditions, the colors of elements are changed in the logic drawing file. Thus it is possible to easily detect an undefined signal and an enabled element.

Title: Internal combustion engine piston
Inventor: ARAI TAKAYUKI
IPC: F02F3/28
Filed: 1989-12-25
Abstract: PURPOSE:To prevent seizure from occurring by changing the ellipse degree of a skirt part slightly from the lower part to the upper part of the skirt part at least in an area where the skirt part faces its side so as to make the skirt part more round. CONSTITUTION:A piston 1 conducts a reciprocating motion inside a cylinder 10 through burnt gas pressure, and the motion is changed into the rotating force of a crank shaft through a piston pin and a connecting rod 9. Resultant force Fg of the burnt gas pressure Pg is divided into force Fc in the axial direction of the connecting rod 9 and force Ft crossing at right angles to the axial center of the piston 1, therefore, the skirt part 6 is pressed against a cylinder 10 by gas pressure and inertia force in a thrust and non-thrust direction, and pressure of the skirt part becomes higher. The ellipse degree of the skirt part 6 becomes less, namely V3 to V1 from the lower part to the upper part in a side area where the skirt part faces the piston pin, and becomes more round. Therefore, the skirt part 6 comes into wide contact with the cylinder 10 in the side range of the piston pin where a load becomes largest on the thrust and non-thrust side where the skirt part 6 is pressed against the cylinder 10.

Abstract: PURPOSE:To reduce cross talking by means of a simple optical system using one light spot by obtaining a reproduced signal and focus and tracking control signals from the outputs of an 8-divided photodetector. CONSTITUTION:A light beam is made incident upon the center of the 8-divided photodetector 11 and signals (b+c+f+g), (a+d+e+h) are respectively obtained from adders 20, 21.

Abstract: PURPOSE: To prepare an alkyl tert-alkyl ether from a tertiary alcohol and a prim. an alcohol using a zeolite modified by a particular metal at a high conver sion rate and with a high selectivity.  
     CONSTITUTION: Using, as a catalyst, a zeolite modified by one or more metal selected from among Groups of IB, VB, VIB, VIIB and VIII of the Periodic Table (especially iron, copper and chromium, or nickel, copper and chromium are pref.), a rare earth exchanged or ammonium exchanged Y-type zeolite is particularly pref., a tert. alcohol and a prim. alcohol are mutually reacted to obtain the alkyl tert-alkyl ether. This method is most suitable especially to obtain methyl tert-butyl ether from tert-butyl alcohol and methanol. Tert. butyl ethers are useful as compounding component to high-octane gasoline. This method is also advantageous because peroxides can be degraded simultaneous with the selective synthesis of the alkyl ethers.
