Title: Fine surface shape measuring instrument
Inventor: YAMAMOTO MASAKI
IPC: G01B21/20
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To actualize a fine surface shape measuring instrument which is resistant to contamination and dust on the surface and has high precision and a high degree of measurement freedom irrelevantly to whether a body to be measured is a conductor or a nonconductor as to the internal surface measurement of a fine hole and a fine groove of a mechanical component. SOLUTION: A probe 1 is vibrated almost at its resonance frequency, the resonance state is detected by a piezoelectric material 19 provided on the probe 1, and an orthogonal detecting circuit detects the probe 1 and the object 13 to be measured coming into contact with each other. Three-dimensional coordinates on the surface of the object to be measured that the probe 1 traces can be found by moving an X, a Y, a Z, and a θ stage, moving the probe 1 and object 13 to be measured properly and relatively, and continuously recording the positions of the respective stages.  Consequently, the fine surface shape measuring instrument can be obtained which can measure the fine surface shape in three dimensions with high precision and a high degree of freedom without being affected by an oxide film, dust, and dirt on the surface irrelevantly to whether or not the object to be measured is a conductor or a nonconductor.

Title: Control of high viscosity material coating robot
Inventor: WATANABE KOJI
IPC: B25J9/10
Filed: 1991-10-17
Abstract: PURPOSE:To apply coating to a coating route in desired bead width and thickness, in the control of a high viscosity material coating robot constituted so as to control an emission amount corresponding to a moving speed by inclining the emission angle of a painting gun in a moving direction corresponding to the moving speed. CONSTITUTION:The emission pressure of a seal agent is controlled so that the emission amount thereof from a coating gun 1 becomes much as the moving speed of the coating gun 1 becomes faster in order to quantitatively apply coating to a coating route. Since the flow velocity of the seal agent at the time of the emission thereof from the nozzle of the coating gun 1 becomes fast when the emission amount increases, the energy of the emitted seal agent impinging against a coating position becomes large and the width of the seal agent becomes wider than predetermined bead width and a bead shape also becomes a cross-sectional shape whose central part is depressed. When the emission angle of the coating gun 1 is inclined when the emission amount is much, since emission energy is escaped in the direction opposite to the moving direction of the coating gun 1, the diffusion of the emitted seal agent is prevented and the coated bead shape becomes a desired cross-sectional shape.

Title: Comparator circuit
Inventor: MATSUZAWA AKIRA
IPC: G01R19/165
Filed: 1987-10-26
Abstract: PURPOSE:To compare the level of a voltage between two potential differences by connecting 1st and 2nd loads to the outputs of 1st and 2nd differential circuits which convert the 1st and 2nd potential differences into differential currents flowing through 1st and 2nd differential output terminal couples. CONSTITUTION:The currents flowing through the 1st and 2nd differential output terminals 3 and 4 are described by monotonous functions of the 1st input potential difference 11 and 2nd input potential difference 12. Further, the couple of currents flowing through the differential output terminals 3 and 4 are in complementary relation and currents flowing through the terminals of the 1st and 2nd loads 41 and 42 are the linear sum of the current flowing through the 1st differential output terminal 3 and the current flowing through the 2nd differential output terminal 4. Consequently, the potential polarities of comparison output terminals 142 and 143 are usable as a comparing circuit because the 1st input potential difference 11 becomes zero when the 2nd input potential difference 12 is multiplied by a certain constant and voltages before and after that are different in polarity.

Title: Heating device
Inventor: HIRAKAWA OSAMU
IPC: H01L21/30
Filed: 1989-10-17
Abstract: PURPOSE:To obtain a heating device which restricts the ambient temperature increase for reducing influence to temperature-adjusting function and safety by providing at least two systems of gas flow paths, namely a low-temperature gas flow path passing at a low-temperature part between the enclosure and a heat-insulating member side, and a high-temperature gas flow path passing at a high-temperature part near a heat source at the inside of the heat-insulating member. CONSTITUTION:Steam and extra nitrogen gas which are generated from a resist of a semiconductor wafer 4 during treatment are discharged from a treatment chamber 5 through a discharge port 21, a space 22, an upper-part discharge pipe 23, and a lower-part discharge pipe 11. Since the inside of the treatment chamber 5 is extremely hot due to heat from a hot plate 6, gas which is discharged through the lower-part discharge pipe 11 is also extremely hot. However, since a gas flow passing at a high- temperature part near the hot plate 6 which is a heat source and that passing a low- temperature part such as an air gap 25 and a discharge duct 9 are separated, for example, gas which becomes hot through the high-temperature part does not pass through the low-temperature part without increasing the temperature at the low- temperature part, thus effectively preventing temperature increase at the outside of an external cover 26 or at the outside of the discharge duct 9.

Title: Clock
Inventor: MURANISHI MASARU
IPC: G10K11/178
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To enable waking up a particular person in a room by cancelling or increasing sounds coming from two speakers by making them interfere with each other. SOLUTION: If a switch 11 of an alarm clock 21 is set in the center and a hand overlaps the short hand at a predetermined time, sine waves current of the same phase flow in speakers 5 and 6 and sounds of the same phase are emitted, but the sounds are canceled to be small at points Q and R on rays 24 and 25 outside the speakers 5 and 6, and the seconds strengthen each other at a point P with the same distances from the speakers 5 and 6. When the switch 11 is set in the center, and if the clock is put near the pillow of a person who wants to wake up and the head of a person who does not want to wake up is put on the line between the speakers 5 and 6, only the person who want to wake up is waken up by the second of the clock 21.  When the switch 11 is set to the right or left, the sound in the set direction from the central clock 21 is large and the sound in the opposite direction is small. So a person who wants to wake up should lie in the set direction from the central clock 21 and a person who does not want to wake up should lie in the opposite side.

Abstract: PURPOSE:To contrive the improvement of the reproducibility of manufacture of an element and the improvement of the gain of element characteristics by a method wherein the height of a mesa is made low to grow a buried layer and thereafter, a clad layer and the like are selectively grown. CONSTITUTION:A diffraction grating is formed on a p-type InP substrate 1 and a p-type InGaAsP tuning layer 5, an n-type InP layer 4, an MQW active layer 3 and a p-type InP clad layer 6 are laminated in order thereon. A mask is patterned on the surface of a growth layer and a mesa stripe is formed by etching. An n-type InP buried layer 7 is grown on a region other than the mesa using a mask used for the etching. In the case where such a buried growth is performed, if the height of the mesa exceeds 1mum, an abnormal growth on the end parts of the mask becomes liable to be generated. In such a way, the height of the mesa stripe is grown in 1mum or shorter in a mesa stripe formation process. Subsequently, after the mask is removed, a p-type InP clad layer 15 and a p-type InGaAsP contact layer 16 are selectively grown.
