Title: Preparation of pentenoic acid ester
Inventor: SHIRATA NORIO
IPC: C07C67/317
Filed: 1979-08-21
Abstract: PURPOSE: To prepare the titled compound useful as a raw material of polymers or an intermediate of medicines, pesticides, plasticizers, etc., in high yield, by the catalytic dehydration reaction of an α-hydroxy-n-valeric acid ester in a gaseous phase in the presence of calcium phosphate as a catalyst.  
     CONSTITUTION: 2-, 3- and 4-pentenoic acid esters are prepared by the gas-phase direct dehydration reaction of an α-hydroxy-n-valeric acid ester in the presence of calcium phosphate as a catalyst. The catalyst is calcium phosphate optionally supported by an inert carrier such as silica gel and obtained pref. by calcining in nitrogen atmosphere at 400W600°C for 2W6hr and pulverizing to 5W50 mesh powder. Since the α-hydroxy-n-valeric acid ester used as the raw material can be easily prepared from n-butylaldehyde available industrially at a low cost, the process is industrially advantageous.

Abstract: PURPOSE:To prevent a fuel supply nozzle from being clogged and to enhance the burning ability of a burner by burning exhaust gas after full growth of frame of ignition gas and then burning particulate by said burning gas. CONSTITUTION:Exhaust gas which contains oxygen flows from apertures 10b formed on a burning cylinder 10 into a combustion chamber 11 to promote burning of ignition gas, on account of which the temperature of the exhaust gas is increased to a great extent inside the combustion chamber 11. Inflammable mixture which is ejected from a nozzle 12 is ignited by a reflux evaporation cylinder type burner 9, and the resultant ignited gas is expedited to be burned by the oxygen in hot exhaust gas. Exhaust gas may be surely burnt even if the concentration of oxygen remaining in the exhaust gas is relatively low. The gas thus ignited and burnt burns the particulate caught by a downstream trap means to purify the exhaust gas which is discharged from the end of an exhaust pipe 2.

Title: Damper mechanism
Inventor: SUGANO TAKUMA
IPC: G06F1/16
Filed: 1986-05-13
Abstract: PURPOSE:To increase the damping effect by adding an L-shaped arm at the side of a rotary member and a taper plane at the side of an equipment to increase the frictional force against said arm in a pop-up mode via a contact with the arm. CONSTITUTION:The front end part of a display device 2 serving as a rotary member is born rotatably via a shaft 3. At the same time, a twist coil spring 4 is set elastically at the lower side of the device 2 to give the rotational properties to the device 2. In addition, an L-shaped arm 5 made of an elastic member is set at the free end side of the device 2 with a folded part 5a. Then a recess part 7 is formed on the side wall of a depressed part 1a of a personal word processor 1. At the same time, a taper plane 7a and a stopper 6 are added. Thus the arm 5 rubs the plane7a and moves up in a hop-up mode, therefore the frictional force is increased toward the upper rotations. Then the higher damping effect is secured.
