Inventor: KANAYAMA MITSUHARU
IPC: E02D7/18
Filed: 1994-08-10
Abstract: PURPOSE:To discern time allowable for taking safety procedures by a method wherein the lowest limit for decrease of working fluid pressure is set in accordance with operation mode of a pile driver, and time required for the pressure decrease to become the set level is indicated when the working fluid pressure decreases below the lowest limit. CONSTITUTION:In the case where breakage is occurred to a hydraulic hose 3 during a pile P is driven with an underwater vibrohammer 1, occurrence of abnormality is indicated by a warning lamp 8 and a warning buzzer 9 at the time when the pressure inside the hydraulic hose 3 decreases to a level below the lowest limit that is set in accordance with the nature of work, namely operation mode, of a pile driver 2. Then, the time required for the pressure inside the hydraulic hose 3 to become zero is indicated on a display unit of a warning device 7, and thereby the time allowable for taking effective safety procedures or the like for the pile P can be discerned.

Title: Two-stage action hand switch
Inventor: ISHII HOMARE
IPC: H01H3/52
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To impart a click feeling at each stage and reduce the size of a switch by sequentially driving a drive plate against first and second springs disposed via a spring spacer at the time of the depression of a push-button, in which only a second boss can penetrate a hole by the effect of a step under a first boss, and operating action switches at first and second stages. SOLUTION: Upon depressing of a push-button 2, a drive plate 5 at the tip of a boss 24 descended against a spring 31 depresses down an active piece 61. When a tension spring is positioned under the fulcrum of a passive piece 62, the passive piece 62 moves rapidly to depress a micro-switch mounted on a switch table 10, thereby completing switch operation at a first stage. Furthermore, a spring spacer 33 abutting against a step difference 23 is descended against a spring 34, so that the drive plate 5 depresses down another active piece 81. Consequently, another passive piece 82 moves rapidly at a predetermined position of the tension spring, to be separated from a photosensor mounted on the switch table 10, so that the switch at a second stage is operated. A sense of clicking can be obtained through the collision of the passive pieces 62, 82 with the switch table 10.

Filed: 1982-10-29
Abstract: PURPOSE:To obtain a carbonaceous anode with a low rate of consumption due to electrolysis for a prebaking type Al electrolytic cell by specifying the specific gravity of aggregate coke as a starting material. CONSTITUTION:Aggregate coke is kneaded with a carbonaceous binder and molded, and the molded body is calcined at 1,100-1,300 deg.C to obtain an anode. Coke having 1.75-1.95g/cm<3> true specific gravity is used as the aggregate coke. Raw coke such as pitch coke or petroleum coke is calcined at about 800- 1,300 deg.C for about 10-15hr, and calcined coke having said true specific gravity is selected from the resulting calcined coke. The quality of aggregate coke is generally controlled in accordance with the calcining temp., and the true specific gravity depends on the calcining temp. The specific gravity depends somewhat on the kind and composition of raw coke as a starting material and conditions during calcination other than temp.

Title: Semiconduct0r integrated circuit
Inventor: TAKAMASU KOUJI
IPC: H01L21/82
Filed: 1990-07-18
Abstract: PURPOSE:To constitute a delay circuit, whose arbitrary amount of delay is large, of a small number of cells and to make it possible to adjust the rise-up and fall-down characteristics of a gate circuit in an arbitrary mode by providing the cell for a delay gate having a transistor so that at least one of its channel length and its channel width is different from that of a transistor constituting a basic inner cell block. CONSTITUTION:The channel length LP, of P-type channel transistors 4a and 5a in a cell 3 for a delay gate and the channel length LN of N-type channel transistors 4b and 5b in a cell 3 for a delay gate are set so that the channel lengths are larger than those of transistors constituting a basic inner cell block 2. The channel widths WP and WN are set so that they are smaller than those of the transistors constituting the basic inner cell block 2. Therefore, current driving capability for the transistors in the cell 3 is smaller than that for the transistors in the other basic inner cell block 2. Therefore, the ON resistances of the transistors 4a, 4b, 5a and 5b are made larger than the resistances of the transistors constituting the basic inner cell block 2. The transistors 4a, 4b, 5a and 5b are connected to a capacitor element 6 which is composed of a diffused layer region 21 and polysilicon 22 which are arranged in a wiring region. Thus, the more longer delay time can be obtained.

Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To contrive the enhancement of the accuracy of the detected value of a current in an output current detecting circuit and the enhancement of the freedom of the design of the circuit. SOLUTION: In an output circuit, which has a first MOS transistor 1 between an output nodal point 5 and a power supply 7, a second MOS transistor 2, which is controlled by the same control circuit as that of the transistor 1, is connected with the output nodal point 5 and moreover, a third MOS transistor 3, which is turned off when the transistor 1 is turned on, is provided between the transistor 2 and the power supply 7. As a potential in a connection nodal point 4 between the transistor 2 and the transistor 3 is in direct proportion to an output current, this potential is compared with a reference voltage Vr1.  As this detected value of a current has no relation with the relative accuracy of the transistor characteristics of the transistors, the accuracy of the detected value is enhanced and as there is not also restrictions on the structure of an output current detecting circuit, the freedom of the design of the circuit is enhanced.
