Title: Intake system of rotary valve type 2-cycle engine
Inventor: YAMAUCHI YOSHIKUNI
IPC: F02B75/02
Filed: 1980-06-28
Abstract: PURPOSE: To prevent the flow-back of the intake from a crankcase of a rotary valve type 2-cycle engine by connecting an empty chamber to the outer end of a branching pipe branched from an intage passage at the location between a rotary valve and a throttle valve.  
     CONSTITUTION: In a rotary valve type single cylinder 2-cycle engine having a combustion chamber 18 and a crankcase 56, a branching pipe 96 branched from an intake passage between a throttle valve 60 of a carburetor 58 and a rotary valve 38 opening and closing by a crankshaft 22 is connected to an empty chamber 92. Thus, the pressure in the intake passage 52 which increases due to rapid closing of the rotary valve 38 is absorbed in the empty chamber 92 via the branching pipe 96 thereby equalizing the pressure in the passage 52 and stabilizing at high level due to the inertia of the intake to prevent the blow-back of the intake from the crankcase 56.

Title: Method and equipment for breaking ammunition containing toxic chemical
Inventor: NIKORA NOERU
IPC: F42D5/04
Filed: 1994-04-26
Abstract: PURPOSE: To destroy munitions containing toxic agents under personally and environmentally safe conditions by closing a pool to seal hermetically with respect to toxic emanation, igniting a pyrotechnic device to fragment the munitions and reopening the pool for another cycle of destruction after releasing the toxic agent into a neutralizing liquid. CONSTITUTION: A thrust cylinder 8 under the moving truck 9 of a single rail lowers munitions into a pool 12, lowers a cover 7 and seals the pool hermetically with respect to toxic emanation. After checking safety, a pyrotechnic device is ignited to explode the munitions. Fragments of the munitions are decelerated by a neutralizing liquid and fall toward a container through a deflector formed by a cone 12' on the bottom of the pool 12. The process continues until toxic agents are neutralized completely. Upon completion of the process, the pool 12 is reopened and the cover 7 is lifted by the thrust cylinder 8 so that the pool 12 can start a cycle for destructing munitions of other production line easily.

Filed: 1984-05-02
Abstract: PURPOSE:To protect a picture image display from breakdown due to discharge of Braun tube by connecting an electric resistance layer in series with an electrostatic capacity produced by the conductive film on the inner face of panel and an explosion-proof reinforcing tool. CONSTITUTION:Upon occurrence of discharge, the electric energy stored in an electrostatic capacity between the inner conductive film 2 and the outer conductive film 3 will flow through a spark gap 10 thus to never cause breakdown of an electronic circuit 9. The electric energy stored in an electrostatic capacity between a metalback layer 5 in the panel 4 and an explosion-proof reinforcing metal 6 will flow from the plus side through a stud pin 16, a shadowmask 15, a contact spring 14, an electric resistance layer 13, the inner conductive film 2 and the electrodes 8, 8' of an electron gun then from the electronic circuit 9 to the minus side of said capacitor C2. Since the electric energy stored in said capacitor C2 is consumed through the electric resistance layer 13, the discharge current to the electronic circuit 9 is reduced considerably resulting in protection of the parts or semiconductor from breakdown.

An automatic gain control circuit 10 controls the level of the signal which is selected by a switch and passed through the line 2 or 3. Then this level is led to an output terminal. A monitor circuit 11 monitors the output level. When the line 2 or 3 is cut off, the circuit 11 detects a fault and sends a switch signal to the circuit 9 to switch the line 2 to the line 3 or vice versa. At the same time, the circuit 11 transmits a time constant switch signal to the circuit 10. The circuit 10 shorten the time constant by a certain time to perform the gain control in a short time and then resets the time constant to prevent a malfunction due to the impulsive noises, etc.

Filed: 1990-04-03
Abstract: PURPOSE: To eliminate the need for deliberate design and manufacture for the fluid feed timing of a control valve by providing a piston means which actuates either a brake or clutch selectively but which does not actuate both at the same time. CONSTITUTION: A spring 44 is compressed between an annular plate 36 and a shoulder portion 46 formed in a sun gear extension 24 and the annular plate 36 is biased toward a brake pad 28. Thereby the brake pad 28 is pressed against the brake engaging surface 48 of the sun gear extension 24 to prevent a sun gear 20 from rotating relative to a transmission housing 30. When a piston 52 is actuated by supplying pressurized hydraulic fluid to a hydraulic chamber 54, the piston 52 moves the annular plate 36 away from the brake pad 28 to direct it toward a clutch plate 32. At the same time, the brake pad 28 is released from engagement with the brake engaging surface 48 and the clutch plate 32 is engaged with the clutch engaging surface 60 of the sun gear extension 24 to thereby rotate the sun gear 20 along with a planetary carrier 14.

Title: Photomask cover
Inventor: OTAKE ETSUO
IPC: G03F1/64
Filed: 1989-04-07
Abstract: PURPOSE:To utilize the intrinsic performance of cellulose ester to obtain the adequate photomask cover by using the thin film of the cellulose ester which is not added with a plasticizer. CONSTITUTION:The processability of the cellulose is improved by addition of the plasticizer thereto but the contamination of the photomask by the absorption of a UV region and the evaporation of the plasticizer is resulted. The thin film having no orientability is formed by a casting system using the cellulose nitrate which is not added with the plasticizer. The cellulose ester dissolves easily in relatively low boiling solvents such as ketone and the finish thickness can be controlled to a prescribed thickness by regulating the soln. concn. and casting thickness. The thin film having 2.8+ or -0.3mum thickness is used for protection of the photomask. The thin film peels naturally from a smooth glass plate if the glass plate is used as a casting substrate and is immersed in water after the solvent removal. The support is obtd. in the uniformly tensed state by placing the thin film in the half-dried state directly on an Al supporting frame and coating a volatile solvent to the contact part of the frame and the film, then drying the coating.
