Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an asymmetric carbonic ester with a suppressed activity of a catalyst even when used for a long period in the method for producing the asymmetric carbonic ester using the heterogeneous catalyst. SOLUTION: This method for producing an asymmetric carbonic ester comprises carrying out a disproportionating transesterification between two kinds of symmetric carbonic esters in the presence of an alcohol at <=100 wt. ppm expressed in terms of concentration in a raw material together with a heterogeneous catalyst when producing the asymmetric carbonic ester by the disproportionating transesterification. Further, the concentration of the alcohol in the raw material is <=1 wt.% and the disproportionating transesterification is a reaction for converting dimethyl carbonate and diethyl carbonate into ethyl methyl carbonate.

Title: Mooring screw fixture
Inventor: TOOMASU JIEI ERISU
IPC: F16B5/02
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To enable the strong fastening so that a tool is required for loosening by providing a one-way ratchet means, which fastens a screw clockwise with a knob and which is removed by using a groove at the time of rotating the screw counterclockwise for loosening, between the knob and the screw. SOLUTION: A C-type spring 50 has an upper tab 51 to be fitted in a notch 35 of a screw 30 and a lower tab 52 to be engaged with a ratchet 40. At the time of rotating a knob 20 clockwise, the ratchet 40 is moved integrally with the knob 20, and a front surface 42 of plural claws 41 is engaged with a front surface of the lower tab 52, and the torque is transmitted to the upper tab 51. Consequently, the torque by a worker is transmitted from the knob 20 to the screw 30. At the time of rotating the knob 20 counterclockwise, the lower tab 52 is deformed inside in an inclined side surface 43 of the claw 41 of the ratchet, and the torque is not transmitted. At the time of loosening the screw 30, an appropriate tool is used in the groove 36 of the screw. Consequently, since the screw is strongly fastened, a tool is required for loosening.

Title: Solid-state image pickup device
Inventor: KOKUBO YUJI
IPC: H04N5/353
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To vary the end of accumulation time by starting accumulation in synchronizing with a trigger signal from the outside and accumulating charge only in a period which is set by a shutter speed setting signal. SOLUTION: When the trigger signal is applied from an input terminal 4 at a restart reset mode, a vertical synchronizing signal is generated by a sync generator 5 in synchronizing with the signal. When the trigger signals are supplied to the sinc generator 5 and a timing circuit 6 from the input terminal 4 at a real shutter mode, a narrow shutter pulse is generated from the timing circuit 6 for CCD 1 in synchronizing with the trigger signal. Thus, the end of accumulation time is changed by delaying the vertical synchronizing signal for prescribed time at the real shutter mode. Thus, an electronic shutter which starts exposure when the trigger signal is inputted and changes shutter speed with the change of the end of exposure time is realized.

IPC: H01G13/00
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a ceramic electronic parts having uniform divided shape dimensions after baking with high production efficiency, by a method wherein a metallic die having the ceiling surface of a protruding part in mesa shape is adopted to form a groove by pressing down the metallic die having the protrusions on a ceramic green sheet surface. SOLUTION: After forming a separating groove by pressing down a metallic die to the surface of a ceramic green sheet 1, the ceramic green sheet 1 is baked. Next, in the step of dividing the green sheet 1 into individual pieces along the separating groove after the formation of an electrode on the surface of the green sheet 1, a metallic die 2 having mesa-shaped protrusions 3 in lattice is used to form the separating groove. Through these procedures, the inverse mesa-shaped separating grooves are formed on the surface of the sheet 1 so that the bottom parts 6 of the separating grooves 1a are made denser than other parts by the pressurization.  Accordingly, when the force to divide green sheet into individual pieces is applied after the baking step the stress is concentrated along the interface between the denser part and other parts, so that the individual pieces may be cleanly divided, at the interface thereby manufacturing the individual pieces having uniform shape dimensions.
