Patent JP-S5973147-A (JP)
Title: Casting method
Inventor: MURAKAMI TAKASHI
IPC: B22D25/02
Filed: 1982-10-18
Abstract: PURPOSE:To enable prevention of cracking in a thin-walled part in the stage of producing a casting having the thin-walled part in continuation with a thick- walled part by packing sand in the longitudinal through-hole of a core provided freely communicatively with the hole opend in the top and bottom surfaces of a casting mold and using such core thereby cooling forcibly the thick-walled part from the central part. CONSTITUTION:A molten metal is charged through a sprue 5 into a casting mold 8. A shutter 13 is released to discharge the dry sand 12 packed in the longitudinal through-hole 10 of a core 7 and the holes 9A, 9B of a casting mold 8 through the hole 9B when the molten metal on the surface in contact with the core 7 begins to solidify upon lapse of a prescribed time after completion of charging. Then, the core 7 is decomposed and discharged at the same instant. As a result, the vertical through-hole in a boss 1A part is made continuous with the holes 9A, 9B of the mold 8 and the atmospheric air flows vigorously as shown by an arrow on account of a difference in temp. The inside surface of the through-hole in the part 1A is thus forcibly cooled and therefore the cracking of the thin-walled impeller 1B continuous with the part 1A is prevented.

Title: Private branch exchange
Inventor: NAKAMURA TOSHIO
IPC: H04M3/533
Filed: 1991-07-23
Abstract: PURPOSE:To simplify the operation by providing a control means enabling a caller telephone set to send a 2nd called telephone number to the private branch exchange so as to eliminate the need for trouble of a called telephone set requiring 2nd hook-on after 1st hook-on. CONSTITUTION:The private branch exchange is provided with a central controller 12 which receives and stored a called telephone number sent from a caller telephone set, deletes the stored telephone number when it is detected that a called telephone set of the called telephone number is not idle, allows the caller telephone set to send a 2nd called telephone number. When the telephone set 2 is hooked off and connected to a register 14, a called telephone number from the telephone set 2 is stored in the register 14. When the central controller 12 judges based on information from a storage section 13 that the called telephone set is not idle, the controller 12 deletes number information in the register 14 and allows a signal source 15 to send a busy tone to the telephone set 2. As a result, the telephone set 2 in the state of hook-off at first enters other called telephone number again.

Title: Checking method for rotation of columnar bevel cut body
Inventor: HACHITANI EIICHI
IPC: G06K9/00
Filed: 1984-08-31
Abstract: PURPOSE:To simplify the algorithm for rotation check of a columnar bevel cut body by using a tangent line to a curve formed by the contour of a section at an inflection point (a lower intersecting point between a section counter and a columnar contour) of said cut body. CONSTITUTION:The standard of rotation round a center line 18 of a needle (columnar bevel cut matter) 16 of an injector is set in the direction (b-state) where a section 19 is parallel to the direction of a camera (not shown here). In this case, a tangent line is coincident with the section 19 at an inflection point 17. When the needle 16 is turned around the line 18, the contour of the section 19 has variation. This changes the inclination of the tangent line and a cut piece at the point 17. Therefore the variation components of the parameters (cut piece, inclination) of the standard tangent line and the parameter of rotations are stored and then measured for a subject. This measured parameter value is compared with those stored. Thus it is possible to check the rotation of the subject within a practical calculation time and with satisfactory accuracy.

Filed: 1989-07-13
Abstract: PURPOSE:To eliminate a resonance sound generated by the abrasion of a cleaning blade by constituting a multiple number of oscillation preventers which prevent the resonance sound due to frequency intrinsic to the length inside a cylinder adhered by adhesives. CONSTITUTION:Lead weights 2 are stuck by a double coated adhesive tape 3 as preventers of oscillation intrinsic to the length to the inside of the drum 1. Further, anything other than lead which is relatively heavy in weight can be used as the oscillation preventer. That is, a photosensitive drum 1 is made of aluminum blank pipe, inside this drum 1, lead weights 2 are adhered with the double coasted adhesive tape 3, and the position where the weights 2 are adhered are, for example; two at the one third point and two thirds point and one at the one ninth point responding to the resonance frequency. Thus, the resonance can be completely eliminated.

Title: Embossing roll
Inventor: YAMADA TAKASHI
IPC: B29C59/04
Filed: 1994-06-29
Abstract: PURPOSE:To obtain natural hand by avoiding repetition of the same patterns by making use of main spindles identical with each other and cylindrical rolls divided into at least two as a pair of embossed rolls whose surface unevennesses are intertwined each other. CONSTITUTION:Cylindrical rolls 2, 12, 3, 13 possessing combination of main spindles 1, 11 and embossed surfaces turning freely are used. Then the cylindrical rolls 2, 12 and 3, 13 are paired respectively each other under a relation where the surfaces are fitted in respectively each other. When the cylindrical rolls 2, 3 and 12, 13 are turned by fixing them, though the identical patterns are repeated away as a whole, the cylindrical roll 3 is fixed by shifting it a little to the 2 and similarly the 13 is turned by shifting it to the 12. Hereby, it becomes that the pattern is shifted by a half of an embossing width and a different patterns are generated as a whole. This is repeated in order and the different patterns can be repeated every lot or customer.

Abstract: PURPOSE:To obtain a hydraulic booster device which can prevent the liquid leak in a simple manner and reduce the stepping-on loss of a pedal, by separating the opening and closing of a flow valve from the shift of a primary piston so that the high liquid pressure is introduced into a power liquid chamber simultaneously with the shift of an operating member. CONSTITUTION:When an action piston 16 is shifted by stepping on a brake pedal, a valve 21 cuts off the communication between the second flow passage 41b and the inside flow passage 22c of a piston 22. Further, a set pin 15 and a holder 19 are engaged by the shift of the action piston 16, and the holder 10 shifts leftward against a spring 18. Then, a ball valve 21 is opened, and the holding liquid pressure in a flow passage 40a flows into the inside of a power hydraulic chamber 40, and a booster piston 9 and a primary piston 6 are pressed leftward. Accordingly, each hydraulic pressure is generated in the first and the second output hydraulic chambers, and supplied into a wheel cylinder. When the hydraulic pressure increases, a hydraulic pressure introducing valve is opened, and the hydraulic pressure is supplied into a power hydraulic chamber 40.

Title: Device and method for improving response time of electromagnetic action device
Inventor: KEEGAN KEVIN RICHARD
IPC: H02P7/06
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To minimize the mechanical response time of an electromagnetic action device by charging a charge storage capacitor with a coil current flowing to an electric coil after stopping excitation at a voltage higher than that of a DC power source and supplying and discharging the coil current to a discharge circuit through the electric coil at the time of excitation. SOLUTION: When the logic signal of a control terminal 17 is 'H', a certain amount of energy is stored by substantially exciting a coil 15 in a steady state. In such a state, the current flowing to an inductor for the excitation is stabilized to a value following the forced response of the coil 15 after passing through a transient response. When it is assumed that a charge storage capacitor 25 discharges to nearly a power supply voltage V+, an FET 31 is pulled down to grounding by means of the bias resistor 33 of a gate and an FET 19. Since the source of the FET 31 is substantially maintained at the power supply voltage V+, the source is biased and the gate becomes 'L' against the source, and then, the P-channel FET 31 is turned on.  The current flowing to the coil 15 does not cause any momentary change and is branched to a diode 27 and the capacitor 25 and the bothterminal voltage of the coil 15 quickly rises.
