Patent JP-S58135546-A (JP)
Title: Fluorescent display tube
Inventor: OOKUBO YOSHIYUKI
IPC: H01J31/15
Filed: 1982-02-05
Abstract: PURPOSE:To obtain a good emission on the display screen of the first- and n-th- line anodes that correspond to the grid on both ends of a display area by applying direct current or a pulse that becomes positive potential for a filament  cathode or a grid scan pulse applied to the first and n-th lines, to an auxiliary  grid. CONSTITUTION:Since auxiliary grids 8a and 8b are arranged thereby removing electronic charge on the surface of an insulating substrate 7, an electron emitted from a filament cathode 5 is not deflected inside and the display screen of the first- and n-th-line anodes 1 emit light excellently. Besides, since a signal that becomes positive potential, i.e. direct current or a pulse for the filament cathode 5 is applied to the auxiliary grids 8a and 8b or a grid scan pulse applied to the first- and n-th-line grids 3 is applied, the electron is not deflected by the potential of a filament support 6. As a result, the display screen of the anodes 1 can  emit light excellently.

Abstract: PURPOSE:To easily constitute a comparator and to shorten a comparing time, by comparing serial bits directly without applying serial-parallel conversion. CONSTITUTION:A first input and a second input are inputted to an IN1 and an IN2 respectively starting from the maximum bits in order, and are inputted to comparison parts 1, 2 and 3. When the values of the bits of the first and the second inputs are equal, an output is issued from a first comparison part 1, and is held at a first holding circuit 4. The output from a second comparison part 2 when the bit of the first input is 1 and that of the second input is 0, and the output from a third comparison part 3 when it is a reverse case of the above, are issued, and are held at a second and a third holding circuits 5 and 6, respectively. The inputs inputted to the second and the third holding circuits are held to the last, and also, the titled circuit is constituted in such a way that, when the inputs to those circuits exist, a following input to another holding circuit is prohibited, and the first holding circuit 4 is reset. After a series of inputs, comparison can be performed by the holding circuit turned ON.

Title: Combustion chamber for direct-injection type diesel engine
Inventor: OOTA SUNAO
IPC: F02B23/06
Filed: 1979-02-17
Abstract: PURPOSE: To lower fuel consumption and to increase output of engine, by forming inwardly projected lips at portions around the periphery of a cavity where atomized fuel injected into the combustion chamber does not come into collision, and thereby mixing fuel and air effectively in the combustion chamber.  
     CONSTITUTION: A cavity 13 is formed in the top surface 12 of piston 11 and fuel is injected from fuel injection nozzle 14 onto the inner surface of cavity 13 as shown at I 1  in the drawing. At portions around the periphery of cavith 13 where atomized fuel injected from nozzle 14 does not come into collision, there are formed lips 15 which are extended radially inwards. When piston 11 comes near to the top dead center, fuel is injected into the combustion chamber as shown at I 1  in the drawing. On the other hand, squish air is divided into s 1  flowing into spray fuel I 1  and s 2  flowing into areas remote from spray fuel I 1 . Since the direction of squish air s 1  is the same as that of swirl S 1 , it acts on spray fuel I 1  effectively so that mixing of fuel and air can be promoted.

Inventor: NAGATE HIROSHI
IPC: G11B7/24082
Filed: 1991-01-17
Abstract: PURPOSE:To make uniform C/N of wobbling RF reproduced signals in prepit and pregroove area by making the track amplitude in the prepit which forms a wobbling track larger than the amplitude of the pregroove area. CONSTITUTION:In a disk-type substrate 11 of an optical disk having a center hole 12, there are provided wobbling tracks comprising a prepit area 13 and a pregroove 14 in a sine curve along the center line of the helical virtual truck. The track amplitude in the prepit 13 is made larger by >=10nm than that in the pregroove area 14, which prevents decrease in C/N of RF reproduced signals in the prepit 13 in the inner area. Thus, uniform C/N of wobbling RF reproduced signals is obtd. in the prepit and pregroove area. Thus, the obtd. recording medium has little read out error for wobbling RF reproduced signals in the prepit area.

Abstract: PROBLEM TO BE SOLVED: To grind a surface at work speed with excellent qualitative accuracy by performing grinding work by moving either one of a disk substrate or a peripheral cutting edge grinding wheel so that side cut work and spark out work are successively and continuously performed on the disk substrate. SOLUTION: A notch margin in the depth direction is enlarged in a side cut work part D1 of a peripheral cutting edge grinding wheel 1, and when the peripheral cutting edge grinding wheel 1 is moved, since the edge of the peripheral cutting edge grinding wheel 1 becomes a factor of generating a crack and a broken piece in a workpiece particularly in work using a fragile material such as a glass substrate 3, a chamfer part is indispensable for reducing damage to the workpiece. A dimension producing part D2 has a function is pre-flat work to reduce a burden to a spark out work part D3 while removing a spiral grinding wheel locus generated in the workpiece by the side cut work part D1 .

Abstract: PURPOSE:To enable to transfer multiple fluids simultaneously with one piezoelectric vibrator by installing a piezoelectric vibrator in the inner part of a casing, thereby forming plural chambers, and then forming each of inlet ports and discharge ports, equipped with a check valve each, in each of these chambers. CONSTITUTION:A cylindrical piezoelectric vibrator 2 is installed in the inner part of a cylindrical casing 1 free of slide motion, and each of pump chambers 11, 12 is formed in and out of this piezoelectric vibrator 2. In addition, each of inlet ports 4a, 4b and discharge ports 5a, 5b is formed in each of these pump chambers 11, 12, while each of suction side check valves 6a, 6b and discharge side check valves 7a, 7b is installed in these ports respectively. Then, an alternating voltage is impressed on the piezoelectric vibrator 2 whereby this vibrator 2 is vibrated so as to increase or decrease its diameter. With this constitution, each capacity of these pump chambers 11, 12 is increased and decreased alternately, thereby having a fluid sucked or discharged alternately in or from these pump chambers 11, 12. Therefore multiple fluids are simultaneously transferrable with one piezoelectric vibrator 1 alone.

Filed: 1989-01-30
Abstract: PURPOSE:To reduce a cost and a space by a method wherein the position of succeeding recording paper is detected in the feeding of preceding recording paper and stored in a memory, and based on the appropriate data the feeding of the succeeding recording paper is controlled. CONSTITUTION:A heat-sensitive ink on an ink sheet 4 is transferred on recording paper 11. When image information is finished on the way of transfer processing, a blind feeding is conducted without a printing action. During the blind feeding, a recording paper position sensor 13 is checked by every one-step feeding, whereby the trailing end of the recording paper is detected. At the time of the discharge of the trailing end of the recording paper, the presence of image information for a next page is judged. Next recording paper has been separately fed already while the trailing end of the preceding recording paper is discharged after passing through a pair of recording paper separation rollers 1. Therefore, before the start of a next page printing the next recording paper is fed by the amount of l=L-k at the time of the leading end thereof reaches the recording paper position sensor 13, where L is a step number from the recording paper position sensor 13 to a printing position and (K) is a step number until the completion of the preceding recording paper discharge. In this manner, the leading end of the recording paper reaches the printing position.
