Title: Production of cold rolled steel sheet for deep drawing
Inventor: KUROSAWA MITSUMASA
IPC: B22D11/06
Filed: 1986-07-03
Abstract: PURPOSE:To produce a cold roller dead soft steel sheet for deep drawing at a low cost with the less processes and energy conservation than heretofore by subjecting a dead soft steel to continuous casting to a thin sheet shape and coiling the sheet, then subjecting the sheet to hot rolling, cold rolling and continuous annealing. CONSTITUTION:The melt of the dead soft steel contg., by weight %, <0.006% C and <0.006% S is continuously cast to a sheet shape having <=50mm thickness at 2-50m/min drawing speed by a continuous casting method and the cast sheet is coiled in a coiling box. The coiled sheet is subjected to finish hot rolling to form a sheet material having 3mm thickness. Such hot rolled steel sheet is subjected to a pickling treatment, by which the scale formed in the hot rolling is removed; thereafter, the sheet is worked to a thin sheet having 0.7mm thickness by the cold rolling. The thin sheet is finally subjected to the continuous annealing at 850 deg.C, by which the cold rolled steel sheet for deep drawing is produced. The need for the stage to reheat the steel slab which is the stock and to subject the same to hot rough rolling is eliminated according to the above-mentioned method; therefore, the heat energy is conserved and the process is simplified. The cold rolled steel sheet is thus produced at low cost.

Title: Cassette tape loading device
Inventor: TANABE MINORU
IPC: G11B15/675
Filed: 1982-09-06
Abstract: PURPOSE:To prevent the damage of a cassette tape loading device when it is under abnormal operation, by discharging a cassette to the cassette inserting position by giving one turn to the cam of a loading mechanism without actuating a lock if the cassette is adversely loaded. CONSTITUTION:A lock cam part 8c is provided to a loading arm 8 which drives a slide angle 11 serving as a cassette shfting means, a shift arm 10, etc. At the same time, a lock arm 16 which is actuated by a solenoid is set opposite to the cam 8. When a cassette is loaded in a correct way, a switch 2 is turned on to revolve a motor 3. Then the solenoid 15 is energized to release the lock, and the cam 8 turns half to shift the arm 10 and the angle 11 in the direction B. Thus the cassette is loaded, and the cam 8 is locked. If the cassette is adversely loaded, the cassette holder does not drop to a normal position. Thus the 2nd switch is not turned on, and the cam 8 has one turn as it is to discharge the cassette to the inserting position. This prevents the damage of a cassette tape loading device when it is under abnormal operation.

Abstract: PURPOSE: To carry out the operation certainly and safely and to enable the use in the filtering of a viscous fluid by a mechanism wherein a hammer blow apparatus is provided between a screw shaft driving a scraper for scraping filtered substance along a filter and an air motor.  
     CONSTITUTION: If substances to be filtered out such as fine particulate soil, sand, ore, scale, metal segments, sludge or the like are contained in a fluid entered from an inlet 12, filtered substances 33 are deposited on a filter 9 to prevent a fluit passage.

When the rotation of an air motor 3  is started, a pinion gear 22 and a large gear 22 is rotated. Because a hammer flow  apparatus is provided between an air motor 3 and a screw shaft 6, a small air  motor can be used even if static friction coefficient of a filter 9 and a scraper 7 is  large and a strong starting torque is needed.

Abstract: PURPOSE:To facilitate manufacture of an oil sump and contrive to facilitate fitting and detaching an oil strainer, by a method wherein a pair of openings are provided at a bottom wall part of an oil sump, one of the openings is communicated with an oil strainer, while the other is communicated with an intake port of an oil pump, and an oil sump cover for covering the openings is fitted from the outside. CONSTITUTION:Since an opening 8a and a penetrating intake passage 9a are provided at a bottom wall of the oil sump 7 and the oil sump cover for covering the opening 8a and the passage 9a and constituting a communicating chamber 13a is fitted, it is unnecessary that a communicating passage extending from the oil strainer to the pump is provided at the bottom wall 8. Since it is sufficient to simply provide the oil pump 7 with the opening 8a, the intake passage 9a and a discharging passage 9b, it is unnecessary to use a core for an oil passage when obtaining the oil sump 7 by casting, and a die casting method can be adopted. In addition, since the oil strainer 14 is fitted to the opening 8a from the outside of the sump 7 by utilizing the fitting of the cover 13, the strainer 14 can be fitted or detached simply by fitting or detaching the cover 13, workability is made favorable.

Filed: 1987-06-23
Abstract: PURPOSE: To obtain a hardly malfunctioning circuit of little power loss by sending a signal of large amplitude corresponding to a voltage drop of diode to a receiving discriminator.  
     CONSTITUTION: When there is no signal in a signal generator 1, the voltage of a battery 2 passes through the parasitic diode 4 of a power MOSFET 3 and is applied to a receiving discriminator 5 and a controller 6. However, said devices neither detect a signal nor make an action so that no power is supplied to a load 7. When the output of a signal generator 1 is applied between the gate 8 and source 9 of said power MOSFET 3, an ON-state is obtained at the level '1' and an OFF-state, at the level '0', and a signal voltage overlapped by a battery voltage is applied to the input terminal of said receiving discriminator 5. The receiving discriminator 5 discriminates said signal and drives the controller 6 to supply said load 7 with power. In said power-supplying state to the load 7, a sufficient DC bias voltage is applied to the power MOSFET, so that the voltage drop of said power MOSFET is very small.
