Title: Sample-hold circuit
Inventor: TSUCHIDA MASAMI
IPC: H03M1/12
Filed: 1987-08-20
Abstract: PURPOSE:To hold a correct sampled result within a sampling period by connecting two sample/hold analog switches to two circuits, forming a difference between respective switching timing values and independently controlling respective switches. CONSTITUTION:A sample-hold pulse is inputted from an analog input terminal 4. The inputted pulse controls the switching timing of the switches S1, S2. In a sampling mode the switch S1 is turned on, and after a prescribed time based upon a delay circuit 5, the switch S2 is turned off. Although both the switches S1, S2 are ON in the initial period of the sampling mode, the S2 is turned off after the prescribed time. Thereby, the sampling period has passed without sampling the ground level. At the time of transferring the sampling mode to a holding mode, the switch S1 is turned off, and after the prescribed time, the switch S2 is turned on. Under said status, the sampled result can be correctly held.

Title: Water cut-off method for construction joint of underground concrete structure and water cut-off structure
Inventor: KAWAGUCHI HIROYUKI
IPC: E21D9/06
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To cut off water, corresponding to a joint opening amount of a joint, by forming a groove on a tip face of a following concrete wall side on a preceding concrete wall, arranging a water expansion seal material in the groove and giving a placing joint to the following concrete wall. SOLUTION: The underground water entering a construction joint H from the natural ground due to opening of the construction joint H is led into a water cut-off space 22, and a water expansion seal material 15 is expanded due to the reaction with the underground water to block the water cut-off space 22. Further, since the construction joint H is blocked and expansion magnification of the water expansion seal material 15 is selected properly, water can be cut off even when a joint opening amount of the construction joint H is large. In this case, it is unnecessary to predict a joint opening amount of the construction joint H in advance and it is possible to correspond flexibly in accordance with the construction joint opening amount. Since the water expansion seal material 15 is expanded toward a water cut-off projecting part 23 side only in a groove 21, it is possible to concentrate expansion pressure of the seal material 15 on the water cut-off projecting part 23 side. Consequently, it is possible to position and fix the water expansion seal material 15 easily at low cost.

Abstract: PURPOSE: To improve a safety side without flowing a large electric current at inverter operating time onto a board pattern by supporting a high voltage transformer and respective parts with a transformer base stand, and connecting tip parts of respective windings and legs of the parts to a conductor of a second transformer base stand. CONSTITUTION: When commercial AC electric power supply 1 is impressed on a primary side circuit 39a, voltage resonance operation is performed by a resonance capacitor 6 and a resonance inductance composed of a switching element 7, a driving control circuit 9 and a primary winding 31, and high frequency voltage not less than almost 20kHz is generated. At this time, an exciting current flows to the winding 1. An electric current of about 60 A flows at peak time, and since it is a high frequency current not less than 20kHz, a litz wire by twisting an enameled wire is wound round the winding 31 so as to reduce a loss by a skin effect.  Since a high voltage transformer 30 and circuits 39a and 39b are mounted on a transformer base stand, an inverter circuit can be operated without exerting influence such as an induction noise from the circuits 39a and 39b on a signal circuit to handle a small signal, so that safety and reliability can be enhanced.
