Title: Automatic speed controller
Inventor: ASADA TETSUYA
IPC: B60W10/10
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To safely travel by reserving automatic departure when detecting an obstacle at a short distance within a specific distance from one's own car in the front or on the side of one's own car even if a preceding car departs. SOLUTION: When an obstacle is detected in a distance measuring area A, or when an obstacle is detected in a distance measuring area B and the obstacle is not a stopping object, automatic departure is judged as impossible, the automatic departure is set and reserved in a prohibiting state. A driver is urged to switch the automatic departure to manual departure of the driver by an announcement to an annunciator. Even when the obstacle is not detected in the distance measuring areas A, B being a short distance within a specific distance, a judgment is made on whether or not the obstacle is detected in a distance measuring area C being a medium distance within a specific distance exceeding this short distance.  In the obstacle judging part, when the obstacle is detected in the distance measuring area C, the moving direction and a moving speed are estimated from a positional change in the obstacle to judge whether or not there is the possibility of entering the distance measuring areas A, B.

Title: Burner
Inventor: KURODA YOSHIYUKI
IPC: F23N5/12
Filed: 1989-04-17
Abstract: PURPOSE:To detect a flaming state with a higher accuracy by positioning both a flame rod and an earth rod which are designed to detect flames between them among flames in a normal state produced in burner ports so that they may approach each other most closely. CONSTITUTION:The fuel supplied from a fuel pipe 11 is vaporized in a vaporizing cylinder 7, and mixed with the air supplied from an air passage 9 and ejected from burner ports 18. A resistance value between a flame rod 20a and an earth rod 21 is reduced by forming flames 23 with sparking discharge from an ignition electrode 24, thereby detecting flames. When the flames 23 are tuned into a lift state due to the excess of air or the drop in the density of oxygen, the resistance value of the flame rod 20a and the earth rod 21 is sharply increased so that the lift state of the flames may be detected clearly. Even when both the flame rod 20a and the earth rod 21 are heated up to a high temperature and the lift state of the flames can be inhibited, the difference between normal operation and operational failures can be clearly identified, since both the flame rod 20a and the earth rod 21 are laid out so that they may approach each other most closely in flames under a normal combustion state.

Filed: 1986-04-25
Abstract: PURPOSE:To make a flexible wire rod into constant-speed travel ordinarily, by detecting a travel speed of the flexible wire rod, and compensating the revolving speed of a winding drum in a way of detecting a difference between the travel speed and the specified speed. CONSTITUTION:In case of a traverse motion 18, a wire rod X is made contact, with pressure, to the side of a speed detecting roll 32 by dint of a spring 36 of a press roll 34, and this detecting roll 32 is rotated after travel of the flexible wire rod X. And, a tachometer generator 45 is rotated via a gear train, generating a DC voltage, and a pickup voltage is ten out and inputted into controller. If so, it is compared with the specified voltage of the specified travel speed for operation, and if there is a difference, a command voltage is compensated, regulating an impressed voltage to a drive motor with a new command voltage, thus rotation of a winding drum is compensated. Therefore, even if a variation is produced in the travel speed of the wire rod X due to an increase in peripheral velocity of the winding drum, the drive motor is regulated to a revolving speed to be adjusted to the required travel speed at once, whereby the travel speed is regurable to be constant as accurate as possible.

Abstract: PURPOSE:To obtain a semiconductor pressure sensor having different silicon diaphragm by forming the silicon diaphragm simultaneously through anisotropic chemical etching using a semiconductor single crystal silicon wafer in which the crystal orientation has an offset angle with respect to (100) face. CONSTITUTION:The crystal orientation of a single crystal silicon wafer 1 has an offset angle of 0.1 deg. with respect to (100) face. The silicon wafer 1 has one side formed with a strain resistor gauge group and the other side simultaneously formed with multiple semiconductor pressure sensors 4 by deep boring 3 of a silicon diaphragm plate having thickness (h). Anisotropic chemical etching having different etching speed for different crystal orientation of the wafer 1 is employed in the deep boring 3. The anisotropic etching proceeds with the side face and the bottom face of the bore being set, respectively, at (111) face and (100) face. Consequently, the silicon diaphragm part has the residual thickness (h) which varies depending on the position within the wafer 1. This method allows mass production of a variety of sensors which can deal with may types of measuring pressure.
