Title: Testing apparatus of strength of concrete product
Inventor: FUJIKURA MITSUO
IPC: G01N3/10
Filed: 1992-04-16
Abstract: PURPOSE:To reduce the cost and to shorten a time required for positioning a head by simplifying a mechanism for moving the head vertically and by enabling a quick drive thereof, in addition, without impairing a function of receiving reliably a counter force of a concrete product caused by pressing. CONSTITUTION:A head 10 is positioned/beforehand at an appropriate position in accordance with the dimensions of a concrete product C by driving a chain block of an elevation mechanism 30 suspending the head 10 and moving it up and down, and a pin 41 is inserted beforehand through an insertion hole 42 at an appropriate position so that it is fitted in and brought into contact with a recessed part of the head 10. The concrete product C is put on a truck 50 and moved below the head 10. The concrete product C is pressed by driving a pressing mechanism 20, the amount of deformation thereof is measured and thereby a strength test is conducted. Since the upward movement of the head 10 is restrained by this pin 41 in this case, a load can be made to act reliably on the concrete product C.

Title: Audio circuit with muting function
Inventor: FUJIMOTO KOICHI
IPC: H03G3/02
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To apply muting simultaneously to plural kinds of audio signals with a small number of components and a simple circuit configuration. SOLUTION: In a muting circuit provided with an amplifier 1A for adjusting the gain of an audio signal outputted from various audio equipments, the gain of the amplifier 1A is adjusted based on a voltage level of a control voltage input terminal ST of the amplifier 1A. Furthermore, a control signal output circuit CS sets a voltage level at a control voltage input terminal ST to a ground level for a muting period and sets to a voltage level in response to a resistance of a variable resistor R4 for periods other than the muting period. When the voltage level at the control voltage input terminal ST goes to the ground level. Since the amplifier 1A applies muting simultaneously to all audio signals, it is not required to provide transistors(TRs) to each audio signal different from a conventional circuit.
