Title: Casting device for continuous padding
Inventor: HASHIMOTO MITSUO
IPC: B22D19/08
Filed: 1992-02-12
Abstract: PURPOSE:To reduce stirring of molten metal at the solidified interface between a mold and the molten metal, to prevent the entrapment of foreign material and to form a padding layer without surface defect by forming a protruding part in a continuous communicating passage between a tundish and the mold. CONSTITUTION:Molten metal circulated stirring force by induction current formed with an induction heating coil 4 is shut off by the protruding part 10 formed in the pouring part of the tundish 3. Further, by forming stagnation P caused by the protruding part at the upper part of the inner surface in the mold, extremely little quantity of impurity invaded into the mold is made to be stayed at the upper corner part of the mold, and the invasion of the impurities into the solidified interface can perfectly be prevented. Further, by using bulging 5 of a molten metal incorporating part in the tundish together with the bulging shape corresponding to flow of the molten metal by the induction current, the shut-off effect for the impurities with the protruding part is increased. By this method, the stirring of the molten metal at the solidified interface between the mold and the molten metal is reduced, and the foreign material is not entrapped to form the padding layer without the surface defect.

Title: One-way clutch
Inventor: HARADA TSUTOMU
IPC: B41J33/38
Filed: 1988-02-08
Abstract: PURPOSE:To perform reliable transmission of a rotation drive force at a low cost, by a method wherein, in a title clutch used for the feed of the ink ribbon of a typewriter, the clutch is formed with a gear rotationally driven in a 2-way and a drive body rotationally driven only in a one-way. CONSTITUTION:During the feed of an ink ribbon, a ribbon winding gear 11 is rotationally driven in a direction (a), and a gear part 11a is rotated in the direction (a). In this case, through a relation between inclination of the tooth of the gear part 11a and that of a tooth 12d of an engaging part 12c, the rotational drive force in the direction (a) of the gear part 11a is exerted on the engaging part 12c, a ribbon winding shaft 12 is rotated in the direction (a), and the feed of an ink ribbon is effected. Meanwhile, during the feed of a correction tape, the ribbon winding gear 11 runs idle based on the ribbon winding shaft 12. This constitution enables formation of a clutch at a lost cost, and performs reliable transmission of a rotational driven force.

Abstract: PURPOSE: To reduce a high speed phase synchronizing current drain when a PLL exists in either one of ends of a lock-up range by turning a current source to a disabled circuit when voltage on the output of a circuit is larger or smaller than a prescribed value. CONSTITUTION: A current supplying source 48 or a current absorbing source 50 is turned on by a gate circuit 46 for leading a voltage controlled oscillator(VCO) 16 to a proper direction in order to obtain synchronization. The mutual connection of the current sources 48, 50 connected in series is connected to a low pass filter on a terminal A so as to quickly charge/discharge a capacitor 22 with electricity. When the PLL is deviated from a phase synchronized state in order to hold control voltage to be supplied to the VCO 16 in the action range of the VCO 16, clamping TRs 42, 44 control the variation of the control voltage on the terminal A. Thereby the VCO 16 is maintained within the controllable range.

Title: High luminance discharge lamp switching circuit
Inventor: SHIDONII EE OTSUTENSHIYUTAIN
IPC: H05B37/02
Filed: 1988-02-08
Abstract: PURPOSE: To ensure operation of a high luminous intensity discharge lamp by providing the first switch to respond to heat which is generated in a resistor and the second switch to respond to an ambient temperature, so that it is lit when the resistance of a photoelectric cell is increased during sunset or the ambient temperature becomes lower than a preset value. CONSTITUTION: During daytime, heat from a resistor 46 keeps a switch S1 in the opening condition. As the sun sets, the resistance of a photoelectric cell 45 increases, and the heat generated in the resistor 46 thus decreases. With the decrease of the heat generated in the resistor 46, the switch S1 is closed, and then power is supplied from a power source 10 to a high luminousity discharge lamp HID 11. As a result, the HID lamp 11 is lit. The second bimetal switch S2 is closed, when an ambient temperature becomes lower than a preset value. With the switch S2 closed, power is supplied to the HID lamp, independent of the quantity of ambient light and whether or not the switch S1 is opened.

IPC: F04B37/16
Filed: 1983-02-21
Abstract: PURPOSE:To prevent the splinters from scattering to outside by accommodating a vacuum rotary apparatus rotatably in an installation housing, by allowing the colliding splinters as product of breakage to rotate the whole vacuum apparatus, and thereby absorbing the energy given by the collision. CONSTITUTION:When a turbo-rotor 32 of a turbo type molecular pump 30 in a vacuum rotary apparatus 14 is damaged of any cause and goes into breakage, the rotation energy of this turborotor 32 is transmitted to the stationary part of this vacuum rotary apparatus so as to impart the impact force due to splinters collision to this stationary part. At this time, the casing 25 of this vacuum apparatus 14 receives the rotational force owing to this collision of splinters to be put into rotation along with the above-mentioned molecular pump 30, and thus the energy given by the colliding splinters is absorbed.

IPC: G04G9/00
Filed: 1995-02-15
Abstract: PURPOSE: To prevent a drop in the service life of a battery by controlling a display drive section and a sound reporting means using a lighting signal and an alarm signal as input data. CONSTITUTION: A lighting means 6 emits light, and illuminates a liquid crystal display body 3, upon receipt of a lighting signal from a lighting switch 5. Also, an alarm signal is outputted at a high level from a count information generation means 1, when a time falls on an alarm setting time. In this case, if the means 6 is not operating, the lighting signal is at a low level and an output signal from an AND gate 7 turns to a low level. At the same time, a signal at a high level is inputted to another AND gate 8 via an inverter 9. Also, an output signal from the gate 8 turns to a high level and a sound reporting means 4 generates an alarm sound. If the the means 6 is operating, the lighting signal is at a high level, thereby keeping an output signal from the gate 7 at a high level and an output signal from the gate 8 at a low level via the inverter 9.  Thus, the means 4 does not operate. According to this construction, the means 4 does not operate even at the alarm setting time, while the means 6 keeps lighting.
