Title: Display tube for light source
Inventor: ICHIKAWA NORIHIRO
IPC: H01J31/15
Filed: 1988-03-31
Abstract: PURPOSE:To uniformly and efficiently radiate unfocused beams on fluorescent faces by installing an accelerating anode in front of a fluorescent character display section as a flat shadow mask plate having multiple window holes passing unfocused beams. CONSTITUTION:An accelerating anode 21 is installed in front of a fluorescent character display section 5 as a flat shadow mask plate provided with multiple window holes 22 passing unfocused beams. When electrons are emitted from one of cathodes 711-733, unfocused beams of electrons pass one of the corresponding control grids 81-83 and pass the corresponding window hole 22 and are applied with the electric field with high voltage and accelerated and radiated to the preset fluorescent faces 5R, 5G, and 5B. In this case, the anode 21 is formed in a flat plate shape as a whole, the potential gradient for the unfocused beams is made wholly uniform, thus the unfocused beams are prevented from being converged only on one part of the anode 21. The unfocused beams are efficiently radiated to fluorescent faces 5R, 5G, and 5B respectively.

Title: Manufacture of permanent magnet and permanent magnet powder
IPC: H01F1/053
Filed: 1992-04-01
Abstract: PURPOSE:To stably manufacture a rare earth-iron-boron-based permanent magnet having a high energy product and a high coercive force. CONSTITUTION:Rare earth-iron-boron-based magnet melting and casting ingot has a multi-phase crystal structure including the main phase R2Fe14B carrying magnetism and a phase richly containing Nd which contributes to coercive force, and the mechanical properties of respective phases are not the same. Within this ingot, the phase richly containing rare earth is more easily oxidized than the main phase and, at the same time, is more easily crushed if hydrogen treatment is given. Thus, the phase richly containing rare earth will be excessively crushed while a required grading of pulverization is being obtained, and the amount of oxygen increases. Therefore, the powder pulverized by a jet mill is sorted by using wind force to the powder having the probability of existence of more than 90% for particle size of less than 5.0mum and having the amount of rare earth more than the input composition and the powder having the probability of existence of more than 90% for particle size of 2 to 15mum and having the amount of rare earth less than the input composition; the powder having the amount of rare earth less than the input composition is compression formed, sintered heat-treated in the production process for the rare earth permanent magnet.

IPC: F16H55/17
Filed: 1984-04-20
Abstract: PURPOSE:To enable prevention of a gear crack owing to stress concentration by forming integrally a flange part provided with a fitting projection to a titled gear and inserting the fitting projection into the groove of a differential case thereby detaining the gear. CONSTITUTION:The revolution of the differential case 5 by a final gear (not shown) is transmitted to a speedometer drive gear 12 which is detained by the fitting projection 18 and a speedometer driven gear 23 meshed with the gear 12 is rotated. A speed is thus indicated. The projection 18 is formed to the gear 12 in the position off the inside peripheral surface of the gear body 15 with respect to the case 5 while the gear 12 is kept driven by the case 5, i.e., on the inside flank of the flange 16 and therefore the stress generated in the gear part 14 in the part where the gear 23 and the body 15 are meshed with each other is prevented from concentrating at the projection 18 of the flange 16. The fixing structure which obviates generation of the gear crack and has high durability is thus obtd.

Title: Strobe type potential waveform measuring apparatus
Inventor: TODOKORO HIDEO
IPC: G01R19/00
Filed: 1985-04-17
Abstract: PURPOSE:To measure a potential waveform proximate to the original waveform of LSI subjected to passivation accurately by combining phase scanning of rough phase split pitch and phase scanning of fine phase split pitch for complementing between the rough phase scan pitches. CONSTITUTION:The waveform B obtained through differentiation of an original waveform A is measured by splitting 400ns period into 1,000. Since 10mus data take-in time is necessary for single point phase, 10ms is necessary for scanning the entire phase. Said measurements are executed 4,000 times to obtain an average. Waveform C is obtained by splitting into 20 where the entire phase is scanned in 20mus which is 1/50 of the case of the waveform B. Consequently, a waveform proximate to the original waveform A is obtained. But only the outline of waveform can be known because of rough splitting. Here, many waveforms C having slightly shifted phase are produced and overlapped. When combining such waveforms as complementing the portion of the waveform C having no data, a waveform proximate to the original waveform but is not the differentiated waveform can be measured accurately.

Title: Capacitance type stroke sensor
Inventor: EMA HIROAKI
IPC: F15B15/28
Filed: 1989-03-30
Abstract: PURPOSE:To remove an error due to the wiring capacity of an output wire and thereby to enable detection of a stroke by covering the output wire with a shielding wire and by providing a potential maintenance means for maintaining the shielding wire at the same potential as one electrode to which the output wire is connected. CONSTITUTION:An output wire 16 is covered with a shielding wire 22, and a potential maintenance means 24 for maintaining this shielding wire 22 at the same potential as one electrode 7 to which the output wire 16 is connected is provided. Since the shielding wire 22 is maintained at the same potential as the output wire 16, a capacitance value of a capacitor formed between them is zero theoretically however long the output wire 16 is. Since the output wire 16 is shielded with the shielding wire 22, besides, no capacitor is formed even when any other substance exists in the vicinity, and a wiring capacity is zero theoretically. Accordingly, the wiring capacity is not contained in the capacitance value detected through the output wire 16. Therefore, the capacitance value being closer to a true value can be detected and thus a stroke can be measured more precisely.

Title: Buffer circuit
Inventor: NASU MASAHARU
IPC: H03F1/32
Filed: 1989-03-30
Abstract: PURPOSE:To obtain a buffer circuit in which the VBE-IE characteristic of a transistor can be eliminated by comprising the emitter current source of an emitter-follower circuit to perform the conversion of the impedance of an output voltage of constant current mirror circuits with the same reference currents. CONSTITUTION:The output V of a variable voltage source VS1 can be expressed as V+VNBE at a point A assuming a voltage between the base and emitter of a PNP transistor QP1 as VN3. Furthermore, it is expressed as V+VPBE-VNBE at a point B assuming the voltage between the base and emitter of an NPN transistor QN3 as VNBE. Here, a current on the emitter of the PNP transistor QP1 goes equal to that on the emitter of the NPN transistor QN3 by a constant current source consisting of a resistor R and the constant current circuits 1 and 2. Thereby, it goes to VPBE=VNBE. In such a way, equal potential V can be always outputted as the output of the variable voltage source VS1 without generating different offset in potential at the point B that is the output based on the output of the variable voltage source VS1.
