Title: Digital/analog converter
Inventor: TAGUCHI TAKASHI
IPC: H03M1/76
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To provide a DAC capable of preventing the situation of simultaneously selecting plural voltages, accurately selecting the voltage-and reducing power consumption. SOLUTION: Synchronized with loading signals, voltage selection signals D1-D6 are outputted from a data register DR2 and supplied to a decoder circuit DA1. However, inverted loading signals inverted by an inverter IN11 are supplied to the AND circuits AND1-AND64 of the decoder circuit DA1 and output is not performed from any AND circuits AND1-AND64 while the loading signals are at a high level. Thus, the switching control signals of the high level are prevented from being simultaneously supplied from the plural AND circuits AND1-AND64 to switching elements SW1-SW64. When the loading signals are returned to a low level, one of the AND circuits AND1-AND64 is turned ON, the corresponding one switching element SW is turned ON and the voltage (v) applied to one terminal of the switching element SW is selected and outputted.

Title: Disc brake
Inventor: KITA YASUO
IPC: F16D65/18
Filed: 1978-01-19
Abstract: PURPOSE:To accomplish simplification in working and assembly as well as miniaturization by housing a piston for pushing a pad and a piston into the cylinder chamber for generating hydraulic pressure. CONSTITUTION:With the operation of a lever 24, a piston 14 is turned so that a ball 25 and a cam surface 16 combine to push the piston 14 forward. The resulting hydraulic pressure drives a first piston 14 to push a pad 15 against a disc D. When the piston 14 is in the most retracted position, i.e., out of braking, a working rod 27 pushes the tip of a valve rod 33 inclined, whereby a reservoir 18 is communicated to a cylinder chamber 12 to compensate for the deficiency in oil due to abrasion of the pad or the like. In braking time, the pressure is withdrawn from the rod 27 so that the rod 33 returns to the vertical position to prevent reverse flow of the oil to the reservoir 18.

Title: Metal mold for centrifugal casting of double-flanged pipe
Inventor: NAKAISHI MASAO
IPC: B22D13/02
Filed: 1980-01-17
Abstract: PURPOSE: To enable a double-flanged pipe free from neck cracking of flange parts to be centrifugally cast with ease of knock-out by using the metal molds inserted with insert metal molds provided with simple shrink absorbing mechanism at one end to the inside surface of an outer cylindrical metal mold.  
     CONSTITUTION: A double-flanged pipe is cast by using the metal molds consisting of an outer cylindrical metal mold 1, two-split insert metal molds 4, an asbestos ring 3, and an adjust ring 2 consisting of an inner cylindrical part 2a, a step part 2b and an outer cylindrical part 2c, rotating the metal molds by a conventional method and pouring molten metal. At the time when the poured molten metal solidifies and shrinks, the amount of shrinkage is absorbed by the deflection deformation of the asbestos ring 3, and this obviates making the removal of the insert metal molds 4 infeasible. The occurrence of a neck cracking phenomenon owing to the cracking at the root part of both flange parts of a casting 5 by yielding to the strength of the metal molds 4 is prevented as well. In the final, the adjust ring 2 of the ring 3 is inserted into the casting 5, and the sound double-flanged pipe is easily cast.

Title: Production of wax pattern for precision casting
Inventor: WATABIKI SEIJI
IPC: B22C7/02
Filed: 1982-01-18
Abstract: PURPOSE:To produce a wax pattern for precision casting which decreases surface shrinkage and torsional deformation by allowing unsolidified wax to flow to the outside of the cavity of a metal mold after the molten wax charged into the cavity solidifies near the inside surface of the metal mold. CONSTITUTION:Molten wax 3 is charged into the cavity of a metal mold 1 through a wax packing port 2 by a method such as dropping by gravity. Refrigerant liquid such as liquid nitrogen or cold water is passed through the fluid flow passages 5 provided in the mold 1 to cool the mold 1, whereby the wax 3 near the inside surface of the mold 1 is solidified. When the thickness of the solidified wax layer 4 is preferably about 2-5mm., the unsolidified wax in the cavity is allowed to flow out. In succession, the mold 1 is opened and the wax pattern is removed. At the time when the plastic deformation of the layer 4 is possible after the outflow of the unsolidified wax, fluid such as gas of 0.2-10kg/ cm<2> is forced into the cavity, whereby the more precise wax pattern is obtained.
