Title: Valve operating device of engine
Inventor: HAYASHI NOBUTAKA
IPC: F01L1/46
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To keep the pressure generated between the top end of a damper member and a pedestal surface in a proper value in a valve operating device for switching the valve lift characteristic in two stages according to the operating state of an engine by specifying the relative position of the damper member of a lost motion mechanism to the pedestal surface. SOLUTION: In low-speed operation of an engine, a rocker arm 1RA is rocked by a low-speed cam 21 to open and close each suction valve 4. At this time, a sub-rocker arm 2 is rocked by a high-speed cam 22, wherein a lever member 7 is in non-engaged state to a stepped part 2B, and a lost motion mechanism 25 is in operated state. When the top end of the sub-rocker arm 2 takes the top position in this state, the head part of a spring retainer 29 makes contact with a pedestal surface 33 so that its central axis CL has a prescribed angle to the straight line vertical to the pedestal surface 33. Thus, the surface pressure between the head part of the spring retainer 29 and the pedestal surface 33 is relatively small.

Title: Electric dust collecting apparatus for gas turbine
Inventor: KATAYAMA HIROYUKI
IPC: B03C3/40
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To improve the dust collecting efficiency of an electric dust collecting apparatus for gas turbines which has reciprocally installed a discharging plate and a dust collecting plate in a casing by shaping the sides along the air flow of the discharging plate into a plurality of projected shapes with an acute angle. SOLUTION: As for a discharging plate 2, the sides along the air flow, that is upper and lower sides, are punched with continuous arc-lines to form a plurality of projected parts 7 with an acute angle. When negative high voltage is applied to the discharging plate 2, an intense electric field is generated between a dust collecting plate and the plate 2, so that corona discharge is generated at the tips of splinters 6. At the same time, corona discharge is generated at the projected parts with an acute angle formed in the upper and lower sides of the discharge plate 2 by punching.  Consequently, powder dust contained in air led from the right side of a dust collecting apparatus is electrically charged by the corona discharge and collected in the dust collecting plate and the upper side and the lower side of the casing due to the function of Coulomb force and electric ion blow and thus high dust collecting function is provided.

Abstract: PURPOSE:To attain immediate resynchronization even in the occurrence of out of synchronism and to reduce missing information in the occurrence of a transmission error by replacing data patterns appearing a lot into a header pattern and sending the result. CONSTITUTION:An analog picture signal is converted into a parallel digital data by an A/D converter 4 and a comparator 5 decides Whether or not the output of the A/D converter 4 is coincident with predetermined fixed data patterns appearing most (or comparatively much). In the absence of the fixed pattern, a transmitter 7 sends a picture signal data as it is and sends a synchronizing header pattern in the presence of the fixed pattern. Then a transmitter 8 applies serial/parallel conversion and decoding to a serial data sent from the transmitter 7, a multiplexer 12 passes a usual parallel data as it is by a command of a header detection section 9 and outputs the predetermined fixed pattern by the header detection section 9 in the detection of the header pattern. Thus, no missing of original information takes place in the reception side and synchronization is taken simply.

Title: Open type kerosene burner
Inventor: HANADA EIICHIRO
IPC: F23N1/02
Filed: 1987-07-16
Abstract: PURPOSE:To remarkably reduce the generation of a smell on extinction, by a method wherein, after an extinguishing command is issued, a fuel feed amount and an air for combustion feed amount are shifted to a feed amount prevailing during low combustion by means of a control means once, and extinguishing motion is then effected. CONSTITUTION:After an extinguishing command is issued, a control device 10 shifts a fuel feed amount and an air for combustion feed amount to a minimum value being enough to allow maintenance of combustion. At a point of time when shifting is completed, a pump 3 is brought into a stop, and extinguishing motion is effected. When a fuel feed amount and an air for combustion feed amount is minimized, during low combustion, a speed at which air-fuel mixture is injected through a burner head 8 is low. Thereby, blow off during extinguishment occurs at a delay point of time compared with that during high combustion, and from two reasons of the one being reduction of production of an intermediate decomposition product and the other being reduction of an absolute amount of fuel gas injected, a smell produced from extinction is reduced.
