Patent JP-H0629832-A (JP)
Title: Ecl circuit
Inventor: HASEGAWA KOICHI
IPC: H03K19/086
Filed: 1992-10-01
Abstract: PURPOSE:To provide an ECL circuit which can work at a low voltage level. CONSTITUTION:The flip-flop circuit of an ECL configuration consists of an ECL circuit part 100 and a buffer circuit part 200. The part 200 consists of an inverted buffer circuit and includes a differential pair of transistors TR 31 and 32. The differential signals sent from the part 100 are applied to the bases of both TR 31 and 32. Meanwhile the Q and *Q output signals are led out of the collectors of both TR 31 and 32. Therefore the level shift-down extent can be set at the comparatively small and optional value for the signals obtained in the buffing states of both TR 31 and 32. In such constitution, an ECL circuit can work at a low voltage level.

IPC: B22D11/10
Filed: 1994-10-27
Abstract: PURPOSE: To prevent an increase in inclusions of the joint parts of different steel kinds and to lessen component mixing of fore and post charges while the frequencies of the joint parts of the different steel kinds are increased by diversification of the steel kinds in continuous casting. CONSTITUTION: Inclusion cleaning devices which rotate molten metal while blowing an inert gas from the wall surfaces of a cylindrical vessel in this vessel are mounted at the molten metal outlet parts of a tundish 2 in a continuous casting method for receiving the molten metal from a ladle 1 at the tundish 2 and supplying the molten metal into a mold from the tundish 2, by which the residual molten metal in the tundish 2 of the fore charge of the joint parts is decreased as far as possible or made preferably zero. The post charge is thereafter poured, by which the increase in the amt. of the inclusions in the joint parts of the different steel kinds is prevented and the component mixing length in the tundish is minimized.

Title: Flexible inserting-tube
Inventor: ARAN AI KURAUTAA
IPC: B32B1/08
Filed: 1989-10-09
Abstract: PURPOSE: To provide a flexible inserting tube with a constant inner diameter, and excellent bending rigidity, fatigue resistance, forceps passage, medical material compatibility, inner friction, and inner pressurizing characteristics, by providing the tube with a flexible tubular inner liner made of polytetrafluoroethylene and a tubular outer sleeve made of an elastomer. CONSTITUTION: This inserting tube 10 consists of a tubular liner made of a porous drawn polytetrafluoroethylene and an outer sleeve 14 made of a tubular elastomer such as silicone, etc. The outer sleeve has a diameter slightly smaller than the outer diameter of the tubular liner before assembling. The tubular liner is inserted into a slightly expanded armor of the outer sleeve and heated to be joined. Next, a tubular end part fitting 16 is inserted into the above- mentioned assembly. One end of the inserting tube is equipped with an inner round groove 18 to prevent a sudden change of the diameter of the inserted tube which may interfere equipment passing. Thus the inserting tube can be bent in a small circle without twisting, pass equipment well even in a bent condition, and be quickly washed and sterilized since it is highly impermeable against various kinds of liquid.

Title: Magneto-optical recording medium and production thereof
Inventor: KIRINO FUMIYOSHI
IPC: G11B11/10
Filed: 1987-10-21
Abstract: PURPOSE:To enable recording and erasing with a weak magnetic field by placing a 2nd thin magnetic film having the axis of easy magnetization in the direction parallel with a substrate adjacently to a 1st thin magnetic film having the axis of easy magnetization in the direction perpendicular to the substrate and on the side opposite to a means for impressing the magnetic field to the 1st thin magnetic film. CONSTITUTION:The 2nd thin magnetic film 13 having the axis of easy magnetization in the direction parallel with the substrate 1 is disposed adjacently to the side opposite to the side where the means for impressing the magnetic field to the thin magnetic film 2 is disposed. Information is recorded on such recording medium by impressing the magnetic field thereto from a magnetic head 18 or by condensing laser light 15 by a lens 16 and projecting the same to the medium from the substrate 1 side opposite thereto. Since the 2nd thin magnetic film 13 exists between the substrate 1 and the 1st thin magnetic film 2, such a magnetic circuit as shown by a dotted line is constituted. The intensity of the magnetic field to be impressed from the magnetic head to the thin magnetic film is, therefore, substantially increased even if the intensity of said magnetic field is the same. The information recording and erasing characteristics are thereby improved.

Title: Magnetic encoder
Inventor: FUKUDA YOSHIAKI
IPC: G01D5/245
Filed: 1985-11-25
Abstract: PURPOSE:To improve position detection precision by shifting an index magnetized part from a multiple strap magnetized part by about 1/8 as much as the magnetization width of a couple of poles and synchronizing the peak of the output waveform of a position detection pulse conversion IX part with the peak of the output waveform of a high-resolution pulse conversion FG part. CONSTITUTION:When the magnetized part of a magnetic drum 1 and a magneto- resistance element 4 are all arranged symmetrically about an axis of symmetry, the output waveform of the FG part and the output waveform of the IX part are outputted having a lambda/8 phase difference. This phase difference is 1/8 as much as the magnetization width lambda of one couple of poles. For the purpose, the phase difference is generated by shifting the axis of symmetry of the index magnetized part 3 from the axis of symmetry of the multipole strap magnetized part 2 of the magnetic drum 1 by lambda/8. Consequently, the peak of the output waveform of the IX part is synchronized with the peak of the output waveform of the FG output part. Thus, the position detection precision is improved.

The leg of the octopus is cut, and washed again with water. The washed octopus leg is immersed in a seasoning liquid (e.g., a mixed solution of sugar and sodium glutamate) for about 15-24hr. The octopus leg taken out of the seasoning liquid is skewered with a bamboo skewer, reformed in manner to elongate the leg as far as possible, and dried to a water-content of about 20%. The dried octopus leg is shaven to thin flakes with a shaver and selected to obtain the objective octopus shaving.

Title: Pulsimeter
Inventor: ODAGIRI HIROYUKI
IPC: A61B5/0245
Filed: 1989-10-11
Abstract: PURPOSE:To prevent the deterioration of S/N of a pulse signal caused by the response time of a light emitting element by setting the control signal pulse width of a sample-hold control means shorter than the pulse width of a turn-on signal outputted from a light emitting element driving means. CONSTITUTION:A sample-hold circuit 5 converts an intermittent signal modulated by a pulse light-received by a phototransistor 3 to a continuous signal by a control signal from a sample-hold control means 4. The width of the control signal of the sample-hold control means 4 for controlling the sample-hold circuit 5 is set shorter than the time when a light emission driving circuit 2 turns on a light emission diode 1. Since the sample-hold control means 4 is provided in addition to the light emitting element driving means 2, the sample-hold circuit 5 can be controlled at the timing being different from the turn-on timing of the light emission diode 1, and the deterioration of S/N ratio of a pulse signal caused by a delay time (TD) and a rising time (tr) being the characteristics of the phototransistor 3 can be prevented.

Abstract: PURPOSE:To prevent shocks due to deceleration or the like which occurs when the drive mode is changed over into a two wheel drive mode from a four wheel drive mode, in order to enhance the travel feelings by increasing the drive power when a free wheel mechanism falls in a fastened condition. CONSTITUTION:When a free wheel mechanism 50 falls in a fastened condition, since a transmission 2 is controlled under a gear shift characteristic in a POW- ER mode, irrespective of whether the drive mode is in a two wheel drive condi tion or in a four wheel drive one, if the drive mode is changed over from the four wheel drive condition into the two wheel drive condition by manipulating a 2-4 change-over switch 71 during a free wheel lock switch 27 being turned off, a 4X4 control unit 61 delivers a drive signal to an actuator 53 so as to cut off the free wheel mechanism 50. In this arrangement, an EAT control unit 60 receives a signal from a four wheel drive mode detecting switch 36 and inhibits temporarily the gear shift characteristic being changed over into an ECONOMY mode until the free wheel mechanism is completely cut off.
