IPC: C07C17/38
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a process for separation of hydrogen chloride from the gas mixture formed by chlorination of methane by cooling and compression followed by washing the resultant gas mixture with liquefied methane chloride.  
     SOLUTION: In this process, hydrogen chloride is separated from a gas mixture forming in the chlorination of methane, which gas mixture contains unreacted methane, its chlorination products and hydrogen chloride formed in the reaction. At this time, the gas mixture is cooled down to 20-50°C, compressed with a pressure of 7-15 bar absolute pressure and cooled down again to 20-50°C. Then, the resultant gas mixture is washed at a pressure of 1-35 bar absolute pressure and at a temperature of -50 to 50°C in order to absorb the methane chloride product and hydrogen chloride formed in the chlorination thereby the gas mixture is separated into the methane-containing vapor phase and the hydrogen chloride and methane chloride-containing liquid phase. Then, the liquid phase is heated to desorb hydrogen chloride from the liquid phase. When necessary, the distillation follows to fractionate the hydrogen chloride-free liquid phase into individual chlorinated methanes.

Title: Diaphragm device
Inventor: SAITO SHUICHIRO
IPC: G03B9/04
Filed: 1989-11-30
Abstract: PURPOSE:To reduce the thickness of the above device and to improve the efficiency of utilizing the space in a lens barrel by oscillating a driving lever within the plane perpendicular to an optical axis, transmitting the movement thereof to diaphragm vanes and switching the diaphragm to be positioned on the optical axis to different diameters, thereby changing the aperture diameter. CONSTITUTION:A magnetic circuit is formed of coils 14, 15 having the central axis parallel with the optical axis and magnetic materials 8 to 11 spaced and disposed to face each other in the optical axis direction. The driving lever 16 is magnetically moved within the spacings between the magnetic materials by this magnetic circuit and further, this movement is transmitted to the diaphragm vanes 3 by which the diaphragm to be positioned on the optical axis is switched to the different diameters to change the aperture diameter. The driving part of the diaphragm vanes 3 is, therefore, formed thinner than the conventional diaphragm device and the size in the optical axis direction of the diaphragm device is shortened. Thus, the efficiency of utilizing the space when this device is built into the lens barrel is improved.

Abstract: PURPOSE:To detect the state of the piston ring speedily, easily, and accurately by projecting an ultrasonic wave on the abutment gap of the piston ring from a scavenging port and receiving a reflected wave from the piston groove surface or ring surface of the abutment gap. CONSTITUTION:The ultrasonic wave is projected on the ring abutment gap 11 of the piston ring 7 from an ultrasonic wave transmitter 100 through the scavenging port provided to the cylinder liner 2 of a two-cycle diesel engine. At this time, when the abutment gap 11 passes the scavenging port 10, the ultrasonic wave is incident on the surface of the piston groove 1a in the abutment gap 11 and reflected to enter an ultrasonic wave receiver 101. When a part other than the abutment gap 11 passes the scavenging port 10, the ultrasonic wave from the transmitter 100 is incident on a part other than the abutment gap 11 and reflected to enter the receiver 101. A measured distance is difference between the former and latter cases and this difference is used to detect whether or not the ring 7 is abnormal.

Title: Method of inspecting leakage of sealed container
Inventor: MARUYAMA MINORU
IPC: B65B57/02
Filed: 1989-12-01
Abstract: PURPOSE:To judge whether on not there is a leak hole by a method wherein in an airtight chamber which is equipped with an eddy current type displacement sensor, a sealed container which has a conductive material at least on a spot to be inspected is placed, and then, depressed quantities of the sealed container under a pressurized condition are detected with time. CONSTITUTION:At a designated position in an airtlight chamber 1, a sealed container 2 is placed. Then, by operating a solenoid valve 8, the inside of the airtight chamber 1 is pressurized from the normal pressure to a designated air pressure, and the container 2 is depressed by doing this. The inside of the chamber 1 is held at the designated air pressure, and by a current type displacement sensor 9, depressed quantities (decreasing quantities of the height of a lid) of the sealed container 2 under the air pressure are detected with time as output voltages. In there is no leak hole such as pin hole, etc. in the container, a maximum depressed quantity (maximum output voltage) is held from when a detected depressed quantity showed the maximum value. On the contrary, if there is a leak hole, the depressed quantity (output voltage) decreases with time from the maximum value, and therefore, it is judged whether there is a leak hole on the sealed container 2 or not.

IPC: F16H3/08
Filed: 1988-12-13
Abstract: PURPOSE:To dispense with a shift valve exclusively used for speed change in a first speed retaining position by selectively supply oil to both two speed oil pressure engaging element and a first speed hole hydraulic clutch through two and three speed shift valve, when a mannual valve is changed to the first speed retaining position. CONSTITUTION:When a mannual valve 9 is changed over to a first speed retaining position, 3 - 4 shift valve 10 is retained at an up shift position, and 2 - 3 shift valve 10 is changed over to the up shift position. Then no oil is supplied to first and third oil paths L11, L16, disconnection with first and second oil paths L11, L12 is made, and oil is supplied to a first speed hold hydraulic clutch CH instead of four speed hydraulic engaging element C. A two speed transmission system and one speed transmission system for bypassing an one- way clutch are established by the 2 - 3 shift valve 102. It is thus possible to aim at cost reduction without need of a shift valve used exclusively for speed change in the first speed retaining position.
