Title: Preparation of chlorotrifluoromethylbenzene
Inventor: AISAKA YOUNOSUKE
IPC: B01J27/00
Filed: 1981-09-03
Abstract: PURPOSE:To obtain the titled substance at low temperature in a short time in high yield, useful as an intermediate for drugs, dyes, agricultural chemicals, etc., by reacting chlorotoluene with hydrogen fluoride and chlorine in the presence of alpha-aluminum fluoride in a gaseous phase. CONSTITUTION:Chlorotoluene is reacted with hydrogen fluoride and chlorine in a molar ratio of 1:(6-20):(4-15) in the presence of alpha-aluminum fluoride at 300- 450 deg.C in a gaseous phase to give the titled substance. alpha-Aluminum fluoride, for example, is obtained by treating active alumina with hydrogen fluoride at relatively low temperature (usually 200-350 deg.C) to give aluminum fluoride, followed by heating it fully at >=500 deg.C. When its activity is lowered by the long-time use, it is treated with oxygen at 400-500 deg.C so the activity can be recovered. A material (e.g., stainless steel) having resistance to a corrosive gas such as hydrogen fluoride, hydrogen chloride, chlorine, etc. is preferable as the material of the device.

Title: Device for controlling anti-skid
Inventor: YANO TETSUNORI
IPC: B60T8/172
Filed: 1988-06-07
Abstract: PURPOSE:To prevent the vibration of a vehicle body accompanying the variation of oil pressure by detecting the peak value in the rise in wheel speed at the time of braking and preventing the lowering of the friction braking force of a friction braking means for a certain time from the point of time of detecting the peak value. CONSTITUTION:When a brake pedal 20 is stepped in, oil pressure generated in a master cylinder 21 is given to a plurality of wheel cylinders 22a-22d via a plurality of actuators 6a-6d to lower the rotating speed of a plurality of wheels 23a-23d. As the braking oil pressure of a motor 12 is fed to the master cylinder 21, each of the actuators 6a-6d is controlled by an anti-skid control circuit 1 to control the rotating speed of each of the wheels 23a-23d. In this case, the peak value in the rise in wheel speed at the tie of braking is detected, and the lowering of the friction braking force of each wheel cylinder 22a-22d is prevented for a certain time from the point of time of detecting the peak value.

IPC: G02B27/22
Filed: 1983-07-29
Abstract: PURPOSE:To display simultaneously, continously and stereoscopically a fluoroscopic video by using spectacles consisting of filter lenses in which right and left lenses have different hues. CONSTITUTION:An X-ray emitted toward an object to be photographed 2 from an X-ray projector 1 makes a fluoroscopic video extending from a point 11 to a point 11A on a photosensitive surface 3. It is photographed by an image pickup device 4, and brought to information processing by a control part 5 so that its video becomes red and can be displayed on a video display surface 6. When this red video is seen through filter lens spectacles in which a lens 7 of the right eye side is blue and a lens 7A of the left eye side is red, the same video is not perceived by the left eye of the same color filter but reflected only to the right eye. Subsequently, when the X-ray projecting part is switched to 1A and its fluoroscopic video is displayed in blue on the reproducing display surface 6, its video is reflected only to the left eye in the same way. Accordingly, when this alternate switching is executed continuously by a period within a residual image time in the same way as a movie, an observer can perceive the same fluoroscopic video 2' as the object to be photographed 2 is seen fluoroscopically by placing both eyes on the X-ray projectors 1, 1A.
