IPC: C10G9/00
Filed: 1993-03-30
Abstract: PURPOSE:To convert a heavy oil into a low-bolding oil of lower viscosity by contacting and reacting the heavy oil with high-temperature water containing supercritical water in a reactor. CONSTITUTION:The charging rate of water in the reactor is 10vol.% or above, and the reaction temperature is 300-500 deg.C. For instance, the apparatus shown in Fig. is composed of a reaction vessel 1 (of a capacity of 50ml), a flange 2, a heater 3, a thermocouple 4, a pressure transducer 5, a temperature controller 6 and a recorder 7. Oil sand is used as the heavy oil, it is washed with toluene, the sand is filtered off, and the filtrate is stripped of the toluene to obtain an oil sands oil sample. This is introduced into the vessel 1, deionized water is introduced at a charging rate of 10vol.% or above preferably 15-70mol.%, and the vessel 2 is sealed with the flange 2. If necessary, in addition to the deionized water, an alkali solution or a catalyst may be added to the vessel 1. The entire mixture is heated up to 300-500 deg.C, and then slowly cooled by stopping the heating. Thus, the oil sands having a viscosity of 25000 cp or higher at 30 deg.C is converted into a low-boiling oil having a viscosity of 5-35 cp at 30 deg.C in a yield of 85-90%.

Abstract: PROBLEM TO BE SOLVED: To provide a table capable of being easily moved. SOLUTION: Wheels 4 are provided only at the lower ends of legs 2 on one side within legs 2, 3 on both sides supporting a top plate 1. Since the wheels 4 are provided only at the lower ends of the legs 2 on one side within the legs 2, 3 on both sides supporting the top plate 1, the other side of the top plate 1 where the legs 3 having no wheel 4 are arranged is lifted, the wheels 4 of the legs 2 on one side are slid on the floor surface 10, and this table can be easily moved. The legs 3 on the other side are mounted on the floor surface 10 when the table is used, the wheels 4 of the legs 2 on one side are not slid by the frictional resistance of the legs 3 on the other side against the floor surface 10 and the movement of the table can be prevented.

Title: Alarm device for lane digression
Inventor: KOSHIZAWA TOSHIBUMI
IPC: B60W30/00
Filed: 1993-03-30
Abstract: PURPOSE:To prevent erroneous detection and erroneous alarming for the lane on the road surface in a tunnel by providing a means for detecting a distance between a vehicle and an obstruction on both sides and an illumination sensor, and by variably controlling the exposure time of a visual sensor from the output signal of the visual sensor as usual. CONSTITUTION:The output signals from right and left distance sensors 5, 6 are read to judge whether the distance to an obstruction (the wall surface of a tunnel or a vehicle running on the same lane) in the left side is less than a threshold D1. When the value is less than the threshold D1, since there is a possibility of colliding with the obstruction, an alarm 3 is energized to issue alarm. When the value is no less than the threshold D1, the distance to an obstruction (the wall surface of a tunnel or a vehicle running on the same lane) in the right side is compared with a threshold D2 (which may be the same as the threshold D1). When the value is less than the threshold D2, since there is a possibility of colliding with the obstruction, the alarm 3 is energized to issue alarm. Erroneous alarming due to erroneous detection by a visual sensor can thus be prevented in a tunnel which is not an appropriate environment for the visual sensor, while contact or collision with the wall surfaces in the both sides of the tunnel or with a car running on the same lane can be avoided.

Filed: 1990-03-22
Abstract: PURPOSE:To provide an on-off valve having excellent airtightness during closing and corrosion resistance by depositing a metal, having corrosion resistance, to at least one of the contact surfaces of a valve body and a valve seat. CONSTITUTION:When an actuating lever 26 is depressed through operation of an actuator 24, a valve body 22 is brought into contact with a valve seat 15 to close a valve port 16. A body 4 and the valve body 22 are formed of a stainless steel, and the valve seat 15 is finished to maximum roughness of 0.3 - 0.5mum. The surface of the valve seat is coated in thickness of 5 - 10mum with an Au layer 17 by a vacuum deposition method, and the under surface, positioned facing the Au layer, of the valve body 22 is polished to form a mirror surface. Since Au is soft and comformable, pressing of the valve body causes airtight closing of a valve, since an on-off valve has no gas permeability, it can be used in an ultrahigh vacuum area, and since the on-off valve has excellent corrosion resistance, it is also used for corrosive gas.
