Title: Ic package
Inventor: TOMINAGA YUKIHIRO
IPC: H01L23/31
Filed: 1989-03-14
Abstract: PURPOSE:To make lead pins hard enough against having and to alleviate correcting work for bending by fixing a part other than th soldered surface part of the mounting surface of the lead pin with an electrically nonconductive coagulant. CONSTITUTION:Lead pins are led out of the side surface of a molded part 1 of an IC package. Solder is applied on the mounting surface of the lead pins. The lead pins which are guided out of the side surface of the molded part 1 other than said soldered parts are covered with an electrically nonconductor coagulant 3 so as to fix said lead pins. Therefore, external force which is applied to the lead pins 2 is dispersed into the molded part 1. The same effect is obtained by fixing the lead pins other than the tip parts of the lead pins with the nonconductive coagulant 3a. In this way, the bending of the lead pins is alleviated, and a step for correcting the bending of the lead pins can be omitted.

Filed: 1986-03-20
Abstract: PURPOSE:To prevent the generation of self-noise being a cause for malfunction of circuit operation by providing plural load transistors (TRs) and drive TRs and connecting a delay circuit to the gate to prevent the generation of a peak current at the time of output inversion. CONSTITUTION:When an input signal D1 rises to an H level, outputs D3, D4 of inverters 17, 20 change to an H level and load MOS TRs Q20, Q21 are turned off simultaneously. Then one drive MOS TR Q27 is turned on by an output D6 of the inverter 21 and an output D7 of an inverter 24 applying the delay successively turns on the other drive MOS TR Q28. As a result, an output Dout rises slowly and goes to an H level. When the input signal D1 descends to an L level, after the drive MOS TRs Q27, Q28 are turned off, the load MOS TRs Q20, Q21 are turned on sequentially. As a result, the output Dout descends slowly and goes to an L level.

Title: Pressure rise control method and device for hydraulic shovel
Inventor: OKA HIDEKAZU
IPC: F15B11/028
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To secure the safety of pressure rise operation by classifying signals detected in response to the operation of each operating lever, into excavation signals and nonexcavation signals, and raising the set pressure of relief valves in the case of detecting only the excavation signals and needing large excavating force. SOLUTION: When operating levers 23cL, 32cR and travel levers 32dL, 32dR are operated, pressure signals detected by sensors 22a-22f are inputted to a controller 23 every moment. When a pressure rise switch 26 is pressed, a pressure rise signal is inputted to the controller 23. The controller 23 classifies the pressure signals detected by the sensors 22a-22f into excavating pressure signals and nonexcavating pressure signals and outputs a command to switch pressure rise selector valves 24L, 24R only in the case of detecting only the excavation signals and detecting the signal of the pressure rise switch 26. The set pressure of relief valves 10L, 10R does not therefore rise in the case of nonexcavation work. There is therefore no motion unexpected by an operator so as to improve the safety of pressure rise operation.
