Title: Magnetic field forming method and device of resin magnet
Inventor: YOSHIDA YOICHI
IPC: H01F41/02
Filed: 1985-02-25
Abstract: PURPOSE:To manufacture a resin magnet having radial and axial directivity by applying radial and axial magnetic fields to a ring charger of a magnetic field forming device to form the resin magnet from magnetic resin in a magnetic field. CONSTITUTION:Magnetic resin is filled in a charger 4 through a resin inlet 7c. A magnetic flux B0 from an electromagnet is branched to a magnetic flux BA passing through pressure plates 9a, 9b and a cylinder 7 and a magnetic flux BB passing a bypass portion 7b. The flux BA becomes a radial magnetic flux in the charger 4 through a cylindrical portion. Since the flux BB flows through the charger 4, it becomes an axial magnetic flux in the charger 4.

IPC: C21B7/10
Filed: 1979-03-24
Abstract: PURPOSE:To enhance the cooling effect of a stave as well as to prevent a cooling pipe interior from the accumulation of sludge or the like by a method wherein a ring like cooling pipe is embedded within a stave for cooling a blast furnace and an inlet and an outlet of cooling water are approached as well as a cross area of a flow changing portion of cooling water is reduced. CONSTITUTION:Plural cooling staves 2 are provided to an iron shelter 1 of a furnace wall of a blast furnace. An inlet 5 and an outlet 6 of a cooling pipe 4 within staves 2 are provided in an approached condition and projected from an opening 7 of an iron shelter 1 to the exterior of a furnace wall. By providing an inlet 5 and an outlet 6 of coolig water almost in a middle portion of a longitudinal direction of staves 2, in case of arranging a cooling box in an upper and lower position of staves 2, there is an advantage capable of separating an iron shelter opening for supplying and exhausting water and an iron shelter opening for an inlet 5 and an outlet 6 of cooling water to a large extent. Moreover, a cross area of an A portion wherein the flow of cooling water is changed from an lower portion to an upper portion as well as a B portion changed downwardly is reduced to raise the flow speed of cooling water and, thereby, the accumulation of sludge or the like as well as the corrosion generation caused to a local electric cell action are prevented.

Title: Selective etching method of laminar structure
Inventor: SHIGEMATSU KAZUMASA
IPC: H01L21/306
Filed: 1980-03-19
Abstract: PURPOSE:To increase thermosoftening property and thermal plasticity of a resist, by wholly exposing this resist, before the heat treatment is applied to the positive-type resist. CONSTITUTION:The first layer 2 is etched, using a positive-type photoresist 1 as a mask. Then ultraviolet rays are applied to the entire face of resist 1.

Title: Correction circuit for s-shaped distortion of vertical deflection circuit
Inventor: SHINO KENJI
IPC: H04N3/23
Filed: 1987-02-20
Abstract: PURPOSE:To eliminate a need for complicated re-adjustment in case of variation in or modification of vertical period by clamping the output of parabolic wave voltage by a simple clamping circuit at a prescribed reference voltage. CONSTITUTION:In a vertical deflection circuit having the clamping circuit 12 on the output-side of a parabolic wave voltage generation circuit 6, if the vertical period of a saw-tooth wave voltage outputted from a saw-tooth wave voltage generation circuit 1 varies due to the variation in the vertical period of a vertical synchronizing input, the central part of the parabolic wave voltage is clamped at the prescribed potential as reference, and inputted to an adder 5. Accordingly, by clamping the deflection center of the DC saw-tooth wave voltage at the prescribed potential as reference, one same level-correction is always executed, and thus one same nonlinear saw-tooth wave voltage can be generated. As a result, a need of adjustment for the variation in the vertical period is eliminated.

Title: Discharge machining power supply
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1984-02-29
Abstract: PURPOSE:To allow a quick charge and improve the efficiency of a power supply by eliminating a charge current limiting resistor and arranging a diode provided in parallel with a charging/discharging capacitor, a charging switching element and a power supply smoothing capacitor on a printed board. CONSTITUTION:When a pulse is applied to the base G1 of a charging transistor Q1 to turn it on, a current I1 flows from a power supply E, a capacitor C1 starts charging, the current I1 is linearly increased by the impedance of stray inductance L3, and the charge voltage VC is gradually increased, thus allowing a quick charge. When the application of the pulse to the base G1 is stopped to turn the transistor Q1 off, a current I2 due to the energy stored in the inductance L3 flows to further charge the capacitor C1. The current I1 and voltage VC to the capacitor C1 can be adjusted by adjusting the pulse width. Accordingly, when the capacitor C1 is charged and a pulse is applied to the base G2 to turn a transistor Q2 on, the voltage VC is applied across the gap between a work W and an electrode P, and a discharge is started.

The switching state of the switch is detected by a detection circuit and input terminals not connected are skipped and the selection of required video input terminals is attained without increasing number of operation keys.

Patent JP-S59163939-A (JP)
Title: Frequency counter
Inventor: TSUNODA YASUHIRO
IPC: G01R23/10
Filed: 1983-03-08
Abstract: PURPOSE:To obtain a stable discriminating output even at the mixing of noise by the constitution that a signal frequency is not discriminated as signal frequency until the frequency of generation of a measured signal frequency is not consecutive for a prescribed number or over and the absence of the signal frequency is discriminated when the frequency of generation consecutive for a prescribed number or over does not exist. CONSTITUTION:An input signal is converted into a pulse signal by a waveform shaping circuit WS, led to a frequency counter circuit FC and also to a monostable multivibrator MM. The circuit FC outputs the presence of a specific frequency f0 as 1, 0 in the period of the input signal. When it is discriminated that the frequency F0 exists, a right shift pulse SPR is generated to an output terminal of an AND gate (AND) 1 and contents of data of a shift register SR are shifted right. An output repeating 1, 0 alternately is outputted to a terminal OUT by an inverter INV2. When it is discriminated that the fequency is not the frequency f0, a left shift pulse SPL is outputted via an AND2 and a DC output is obtained in a terminal OUT. Thus, a stable discrimination is attained even at the mixture of noise.
