Title: Method for detecting solution heat treatment area
Inventor: NAKASHIRO NORIYUKI
IPC: G01N33/20
Filed: 1990-03-20
Abstract: PURPOSE:To secure the reliability and safeness of a plant by non-destructively measuring the depth of a solution heat treatment area obtained by executing the solution heat treatment of a sensitization area of austenitic stainless steel or the like by laser beams or the like. CONSTITUTION:In a welding plate for austenitic stainless steel, the surface of a base material 5 having a welding metal 2 which is the solution contacting face 4 of a welding heat influence part 3 is irradiated with laser beams 1 radiated from a laser oscillator 6 to execute the solution heat treatment of the surface and the width of a two phase area 9 generated on the center of the surface of the solution heat treatment are is measured. The correlation data between the width of the area 9 and the depth of the solution heat treatment area 8 are previously prepared in a laboratory size and the depth of the area is measured from correlation data between the width of the area 9 of a target to be measured and the laboratory size data, so that whether solution heat treatment is sufficiently executed or not can be checked. Thereby, the depth of the solution heat treatment area 8 can be non-destructively detected by the surface processing method of sensitization area whose corrosion resistance is low.

Title: Voice solid-state sound recording and reproducing ic
Inventor: MATSUMOTO SHOICHI
IPC: G10L19/00
Filed: 1990-03-20
Abstract: PURPOSE:To facilitate prevention against the generation of a pop noise by preparing one kind of slope data matching the steepest state, judging the polarity of voice data, and adding the slope data on the voice data behind it. CONSTITUTION:The IC consists of an A/D converter 1, a control block 2, a D/A converter 4, and a storage memory 5. When sound recording is interrupted or stopped, (1) is written as ADPCM data in the voice data storage memory 5 about 20 times following the voice data and then (0) is written several times to make the transition point from the voice data of a voice output waveform to the slope data smooth. Therefore, a muting circuit as hardware need not be provided and circuit components do not increase in number; and the need for complicate control wherein plural kinds of slope data are prepared and proper one is selected at each time is eliminated. Consequently, the pop noise prevention is facilitated.

Title: Method of monitoring frictional coupling between tire of wheel driven and road
Inventor: RIYUUDEIGERU UEEBERU
IPC: B60W10/04
Filed: 1991-04-01
Abstract: PURPOSE: To inform a frictional connection state between a roadway and a driven wheel tire earlier to a driver of an automobile during ordinary driving operation. CONSTITUTION: A wheel peripheral force working synchronously with a wheel slip of a driven wheel is measured sequentially in an ordinary driving operation and in a semi-ordinary driving operation. In this case, the wheel slip is measured with a precision within a range of 0/∞. A pair of wheel peripheral force/wheel slip values found on a substantially dried roadway are stored, and if a value pair showing a greatly larger wheel slip as against that of the stored value pair having a substantially equal wheel peripheral force is generated or detected afterward, it is evaluated that the frictional connection state is greatly deteriorated.

Title: Hand display-type timepiece
Inventor: HAYAKAWA MOTOMU
IPC: G04C3/00
Filed: 1985-04-01
Abstract: PURPOSE:To improve the durability of a timepiece and to reduce substantially a load applied to a motor by providing a means capable of switching a contact point between a hand and an electrode on a dial into a contact state and a non-contact one. CONSTITUTION:Plural electrodes 2 are disposed on the dial 3. When a crown 4 is at a normal position, the contact point between the hand 1 and the electrode is separated. When the crown 4 is pulled, a crank link 5 is rotated with a crank spindle 6 as a center to lift the dial 3, and the electrodes on the surface contact the hand 1. By using the switching means, the electric conduction between the hand grounded to a potential VDD and the electrode 2 on the dial 3 can be released in the state where the crown 4 is pulled. Since the position of the hand can be detected the moment both electrodes contact each other by pulling the crown 4, it is unnecessary that the contact point between the electrodes is rotated in the contact state, and the load to the motor and its durability are not considered.
