Title: Test circuit
Inventor: TATENO SUMIO
IPC: G01R31/28
Filed: 1991-05-23
Abstract: PURPOSE:To make it possible to output several kinds of internal monitor signals by a method wherein each pattern detecting circuit is made to operate by inputting a specified pattern to a pin used for input data when a pin for monitoring is set. CONSTITUTION:When a pattern detecting element 2 once detects a pattern, a control signal is sent from an NOR gate 5 to a bidirectional buffer 1. Receiving the control signal, the buffer 1 puts a pin in a state of output. A selector 3 is controlled by the pattern detected by the detecting element 2 and a monitor signal to be outputted from the selector 3 is selected by the control signal and delivered to the buffer 1. When the pattern is detected once more by the detecting element 2, it stops sending the control signal to the buffer 1 and the buffer 1 is restored from the state of output to an ordinary state of input. Accordingly, one pin of a pin terminal can be used in two ways as a data input pin and a monitoring output pin and several kinds of monitor signal can be outputted from the input pin.

Title: Impedance transformation circuit
Inventor: FURUBAYASHI HIDEKI
IPC: H03H7/40
Filed: 1978-09-25
Abstract: PURPOSE:To improve the energy transmission efficiency by making easy for the impedance matching, through the use of transformer changed for the impedance transformation ratio depending on load. CONSTITUTION:The transformer 5 incorporating diodes 6, 6' is connected between the power supply side terminals 7, 8 and the load side terminals 11, 12. With this constitution, the output impedance of the non-linear transformer 5 is changed depending on the change in the load 4. When the power supply voltage is small and the input voltage applied to the terminals 7 and 8 is small, the diodes 6, 6' of the transformer 5 are open and current is fed to the terminals 11 and 12 via the terminal 9, then the output impedance between the terminals 11 and 12 is greater, In this case, since the load 4 is also a greater value, the matching is made. If the input voltage at the terminals 7 and 8 is greater, the diodes 6, 6' are shorted, current is fed via the terminal 10, and the impedance between the terminals 11 and 12 is lower. Since the load 4 is smaller, the impedance matching is obtained.

Title: Reciprocation type compressor
Inventor: SAKAI TOSHIKAZU
IPC: F16N15/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent generation of abnormal wear of a connection part between a piston pin and a connecting rod in the subject compressor. SOLUTION: Since a connecting rod 5 performs reciprocation motion to a fixed piston pin 13 at a connection part between the rod 5 and the pin 13, a fluid film caused by lubricant is hard to generate, leading in generation of metal contact at a part of a sliding surface. At this time, a lubricative film 14 having a frictional coefficient of 0.1 or less formed on a surface of the pin 13 and a metal contact part at the connection part of the rod 5 slide on each other, and accordingly the coefficient is kept to be 0.1 or less. As a result, a temperature increase in the vicinity of the connection part between the rod 5 and the pin 13 is reduced to prevent vaporization of lubricant, resulting in prevention of changeover to a dried frictional condition.
