Title: Power source for ic tester
Inventor: NAKAMURA TOMOHARU
IPC: G01R31/28
Filed: 1985-07-22
Abstract: PURPOSE:To evade errors in measurement by connecting a forcing and a sensing power supply terminal through a resistor, and reading and displaying the voltage at the forcing power supply terminal on a digital voltmeter. CONSTITUTION:If a line which short-circuits the terminals F and S becomes open or is connected with high resistance owing to some accident, for example, when the line is open at a position X as shown in a figure, a sensing circuit 1 operates to hold the terminal S at a programmed voltage, so a current flows from the terminal F to the terminal S through the resistor 12. Then, the resistor 12 has a potential difference and a voltage which is about 0.6-1V higher the voltage (programmed voltage) at the terminal S is applied to the terminal and becomes an applied voltage (abnormal voltage) to an IC 2 to be measured. The forcing power supply terminal F, however, is monitored through the digital voltmeter 3, so if an abnormal voltage is developed, the erroneous measurement of the object IC 2 with the abnormal voltage is evaded by confirming the read value on a voltage display device 4.

Title: Communication system
Inventor: KOBAYASHI KAZUTOMO
IPC: H04B7/15
Filed: 1985-07-22
Abstract: PURPOSE:To reduce a wait time to send a single packet by allowing plural predetermined slave stations to send only the single packet even when no reservation is issued in advance to a transmission command from a master station. CONSTITUTION:A packet to be sent to the 3rd and 4th slave stations receiving a progress frame PF (G2) is provided, it is sent at the same time to cause collision. When a master station detects the collision, the progress frame is sent to the slave stations respectively. In such an example, a progress frame PF (3) is sent to the 3rd station at first and then a progress frame PF (4) is sent to avoid the collision. When only the single packet exists, the frame is sent without reservation, a short polling period is enough and the transmission wait time is reduced remarkably.

Title: Long-life compact magnetic fluid seal
Inventor: KURUDEITSUPU RAJI
IPC: F16J15/43
Filed: 1988-06-29
Abstract: PURPOSE: To elongate the annular gap for retention of magnetic fluid so as to extend the seal life by retaining the magnetic fluid in the annular gap between the shaft and housing by the magnetic field of the magnetic assembly formed by an annular magnet and a pole piece. CONSTITUTION: An annular magnet 36 and an annular pole piece 42 are arranged on the inner peripheral surface of a housing 32 in a superposed way. Each end surface 44, 46 abutting a magnetic permeable shaft 30 forms the first and second annular gap 40, 50 respectively, where a magnetic fluid 52 is retained to seal the shaft 30. In such a case, the inner diameter of the annular pole piece 42 is slightly smaller than the inner diameter of the annular magnet 36 and the outer edge of the end surface 48 is rounded to form a bevel 54. Thus a magnetic flux density of the second gap which is different from that of the first gap 40 is constituted for limiting the outward expansion of the magnetic field, i.e., the expansion of the magnetic fluid 52, and limiting the splashing thereof. In this way, it is possible to extend the seal life.

Filed: 1988-07-01
Abstract: PURPOSE:To heighten the junction strength of the substrate of a circuit with its terminal so as to enable enlargement of the substrate of the circuit supported by the terminal, by also embedding and fixing the terminal fixed with solder to a circuit film into a resin substrate. CONSTITUTION:A subject having a terminal mounted and soldered to the peripheral portion of a circuit film 21 is set inside a molding metal pattern, and resin is thus molded to form a resin substrate 25 on a single face of the circuit film 21, and also the circuit film mounting portion of the terminal 13 is embedded into the resin substrate 25. The junction strength of a circuit substrate 26 with the terminal 13 is thereby heightened; even when the circuit substrate 26 supported by the terminal 13 is enlarged, there will hence be little possibility of breakage of its jointing portion.
