Title: Mark forming method for cathode-ray tube
Inventor: OKAZAKI TAKAO
IPC: H01J29/86
Filed: 1986-03-25
Abstract: PURPOSE:To form marks to read as a production management information easily and rapidly, by fixing a specific base agent at a specific position of the envelope of a cathode-ray tube, and then producing a melting mark on the base agent by a high density energy radiation means. CONSTITUTION:To a specific position in the periphery of the envelope 1 of a cathode-ray tube, a base agent 2 consisting of a frit glass or the like mainly made of PbO including at least ZnO and B2O3 is stuck. Then, laser beams 6 from a high density energy radiation means 3 with a radiation source such as YAG laser is radiated over the base agent 2, to make only the radiated spot melted at a high temperature leaving the melting marks 4. Depending on the difference of reflection rate between the melting marks 4 and the base agent 2, a bivalent mark M or the like is displayed. Therefore, marks to read as a production management information of a cathode ray tube can be formed stably and rapidly without erasing or staining, in the process of heat-treatment or chemical treatment.

Title: Amplitude converting circuit
Inventor: MATSUMOTO KOICHI
IPC: H03K19/00
Filed: 1987-03-23
Abstract: PURPOSE:To decrease the reduction in the operating speed due to the increase in the load capacity in increasing fanout by adopting the emitter follower of a bipolar transistor (TR) to an output stage in place of an MOSFET. CONSTITUTION:An ECL buffer is constituted by TRs 1, 2, resistors 3, 4 whose resistance is Rc and a constant current source 6. A P-channel MOSFET 5 switches a base bias current path of the bipolar TR 7. An N-channel MOSFET 11 is turned on when the TR 7 driven by a current mirror circuit comprising C-MOSFETs 9, 10 is turned off to play a role to draw the voltage at an output terminal 13 to OV. The N-channel MOSFET 12 is driven by a current mirror circuit comprising C-MOSFETs 9, 10 similarly as the MOSFET 11, and when the TR 7 is turned off, the MOSFET 12 is turned on to draw a base electric charge of the TR 7 thereby reducing the transition time when the TR 7 is turned off. Thus, the deterioration in the high speed performance of the circuit is prevented.

Title: Tire vulcanizing mold
Inventor: MUTAGUCHI YOSHITAKA
IPC: B29C33/02
Filed: 1981-05-08
Abstract: PURPOSE:To make deep tread grooves easily in dropping and moving a peripheral segment inwardly by a method wherein a cam, whose inside inclines in the reverse direction against the inside of a fan-wise taperring, is projected on the upper surface of the outer periphery of the drag of a mold. CONSTITUTION:When a green tire B is mounted on the drag 1 and the cope 2 is dropped, a peripheral segment 5 falls with the cope 2 but after a cam groove 5d is fitted to the cam 9, the peripheral segment 5 is guided by the inner slide 9a of the cam 9 and falls in the direction of the arrow P. At the same time that the taper ring 2a touches the drag 1 the peripheral segment 5 arrives at the innermost end of the stroke and stops moving. Thus, as soon as the peripheral segment 5 moves inside, the peripheral segment 6 falls at the same speed as that of the tread part Ab of the green tire B to provide a tread groove of uniform depth.

Abstract: PURPOSE:To correctly extract an observation object, formed on a semiconductor substrate as a thin film pattern of uneven shape with height difference, without causing deformation and rupture. CONSTITUTION:The surface of a transfer film 5 is dissolved and pressed to a substrate 2 with an observation object 1 exposed, and separated so as to transfer the observation object 1 to the surface area of the transfer film 5 from the substrate 2.

A sample with the pressure buffer layer 6 formed is submerged in the polar solvent, and the transfer film 5 is dissolved and removed at the liquid temperature lower than the fusing point of the non-polar material. The liquid temperature is then raised to the fusing point of the non-polar material or higher to fuse and remove the pressure buffer layer 6. Prior to the formation of the pressure buffer layer 6, the desired area of the observation object transfer face may be covered to form a reinforcing film formed of amorphous material such as carbon.

Title: Multilayer capacitor
Inventor: AKIMOTO YOSHIO
IPC: H01G4/30
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a mullilayer capacitor which has no internal structure defect. SOLUTION: Internal electrodes 23 and 23a to 23d are each formed thereon with a plurality of projections 25, and then stacked with dielectric layers to form a multilayer capacitor. Since this causes the projections formed on the internal electrodes to be engaged into the dielectric layers so that bond strength between the internal electrodes and dielectric layers is increased, internal distortion locally accumulated in the internal electrodes can be avoided due to elimination of migration inside of layers. Thus there can be obtained a multilayer capacitor which can remarkably reduce a generation frequency of structural defect (such as delamination or crack) caused by oxidation expansion of the internal electrodes of Pd, etc., with a high reliability.

Abstract: PURPOSE:To attain the reduction of weight, shortening of construction, and enhancement of fire proofness by a method in which the lower part of two web steel frames is integrated with a lower concrete side, web steel frames covered with a fire-proof cost are set between large beams, and detachable floor panels are placed on the web steel frames. CONSTITUTION:Two long web steel frames 1 are erected in parallel in the widthwise direction, and concrete 9 is placed to below the frames 1 to embed partly them in order to form a lower slab 2. A fire-proof covering 10 is applied to the portion projected from the slab 2 of the frames 1 and the frames 1 integrated with the slab 2 are set between large beams 8 by hooking the ends of the frames 1.
