Title: Suspension control device for vehicle mounted with behavior control device
Inventor: FUKUYAMA KENSUKE
IPC: B60G17/015
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide an internal pressure control of a suspension cylinder, which improves a behavior control effect of an automatic brake, so that desirably, there is no change in the posture of the vehicle body. SOLUTION: When a behavior control is not working, shown with broken underlines, internal pressures of cylinders for front wheels 11FR and 11FL are increased by an amount αcorresponding to a reduction in speed, while internal pressures of cylinders for rear wheels 11RR, 11RL are decreased by an amount β corresponding to the reduction in speed, for controlling pitching.  When under a behavior control of a braking FVR of the right front wheel 11FR, shown with solid underlines, an internal pressure of the cylinder thereof is increased by an amount (ΔKXG×XG corresponding to a reduction in speed XG while an internal pressure of the cylinder for the left front wheel 11FL is decreased by the same amount, and an internal pressure of the cylinder for the right rear wheel 11RR is decreased by the same amount, and an internal pressure of the cylinder for the left rear wheel 11RL is increased by the same amount. The right front wheel 11FR increases its braking force to FVR due to the rise in internal pressure, for increasing its behavior control effect.  A sum of the internal pressures of the cylinders for the front left and right wheels equals a sum of the internal pressures of the cylinders for the rear left and right wheels, so that a pitching posture remains constant. A sum of the internal pressures of the cylinders for the right-side front and rear wheels equals a sum of the internal pressures of the cylinders for the left-side front and rear wheels, so that a rolling posture remains constant.

Title: Scroll type compressor
Inventor: KAWAKAMI MITSUNORI
IPC: F04C28/16
Filed: 1990-01-31
Abstract: PURPOSE:To protect a scroll without lowering volume efficiency by providing by-pass holes at the specified spaces apart along the scroll type passage of a scroll, as well as providing closing members, opened at the time of receiving abnormally high pressure, in a passage for communicating by-pass holes mutually. CONSTITUTION:A buffer chamber 3 of appropriate volume is formed at a body 1a, and this buffer chamber 3 is communicated with a scroll type fluid passage formed by a partition wall 1b, through plural by-pass holes 4, 5. In the state of pressure in a compression chamber becoming abnormally high, the compression chamber moves along the partition wall 1b according to the rotation of a driving scroll 1, and at the time of reaching the position of the by-pass hole 4 or 5, this high pressure acts upon the end face of a closing member 9 or 10. When this pressure is larger than the pressing force of a spring 13, a valve body 8 moves downward while compressing the spring 13. The end faces of the closing members 9, 10 are positioned lower than slits 6, 7, and therefore the by-pass holes are mutually communicated through the slit 6, buffer chamber 3, slit 7 and by-pass holes 5.

Abstract: PURPOSE:To obtain a copy with high quality without reducing a copying speed by executing a pre-scanning of a 2nd page following the pre-scanning of a 1st page and copying images in respective pages with proper exposure values corresponding to respective images. CONSTITUTION:A CPU54 discriminates an automatic exposure (AE) mode through an AE sensor 51, and when the AE mode is selected, lights up a light source 21, starts an optical part 2', starts the pre-scanning operation, and after waiting until the sampling timing for the 1st page, stores sampling data in a RAM57. Similarly, the CPU54 stores the sampling data of the 2nd page similarly, lights up the light source 21 with an exposure value based upon the data of the 1st page and starts the optical parts 2'. After copying the 1st page, the CPU54 turns off the light source 21 and moves the optical part 2' backward. Subsequently, the CPU54 discriminates a continuous copy mode, and when the mode is not selected, discriminates the AE mode again. At the selection of the AE mode, the CPU54 copies the 2nd page on the basis of an exposure value for the 2nd page, turns off the light source 21 and moves the optical part 2' backward to end the copying operation for a series of pages.

In this manufacturing method, during the growth of the clad layer comprising Inx Gay Alz B1x-y-z N (0<=x,y,z<=1, 0<=x+y+z<=1), the growing temperature or the pressure in a growing tank is changed from the first temperature to the second temperature or from the first pressure to the second pressure. Then, the changing of the temperature and H2 gas is performed during the growing of a p-AlGaN clad layer. Thus, the defect density is decreased, the efficiency of the GaN-based semiconductor is improved and the threshold current is decreased.

Title: Digital/analog conversion circuit
Inventor: YAMAGUCHI KAZUHIDE
IPC: H03M1/76
Filed: 1989-01-30
Abstract: PURPOSE:To improve linear error characteristic by connecting a bias circuit to the intermediate point of the resistance element of a resistance string type digital/analog conversion circuit, and fixing a voltage at a desired contact voltage compulsorily. CONSTITUTION:The resistance string type digital/analog conversion circuit 2 and the bias circuit 1 are connected between a reference voltage source 50 and a ground voltage, and the output of the bias circuit 1 is connected to the digital/analog conversion circuit 2. Since a very small resistance element compared with the resistance element 100 can be used as the resistance element 17 included in the bias circuit 1, the influence of a piezoelectric effect can be ignored, as well and an intermediate voltage can be generated with high accuracy. However, when it is desired to attain high accuracy with a level not being ignored in the offset voltage of a buffer amplifier 11, the higher accuracy can be attained by attaching a trimming circuit. In such a manner, the linear error characteristic can be improved.

IPC: G01B11/16
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To correctly determine the distortion of a tile or recognize a site of the distortion of the tile. SOLUTION: Four distance detection sensors 1 are provided above a belt conveyer for measuring a distance to a tile being carried along a measurement line L. Thus a plurality of pieces of measurement data along the measurement line L are sent to a personal computer 3, and also an average value can be obtained for each small region with the measurement line L equally divided. Then by comparing the average value as a measurement value M with a preset reference value A, the distortion of the tile is determined. Therefore, since measurement is performed in a line, even partial distortion can be correctly determined, and further an average is obtained for each of equally divided small regions, thereby preventing erroneous measurement due to burrs or the like.
