Title: Manufacture of hard alloy powder
Inventor: MARUYAMA MASAO
IPC: C22C1/05
Filed: 1990-09-21
Abstract: PURPOSE:To manufacture the above hard alloy powder suitable to pressing by adding solvent to the specific element constitution of raw material powder, wet-mixing, pulverizing and drying the powder. CONSTITUTION:To the raw material powder consisting of cemented carbide and cermit composed of carbide, nitride and carbonitride of IVa group, Va group and VIa group metal elements in the periodic table of elements and iron group metal elements, ethanol containing 2-15wt.% water is added as solvent, the mixture is wet-mixed, pulverized and further, dried. The reson why the content of ethanol to be added to 100% water is specified to 2-15wt.% is that in the case of <2wt.%, effective addition is not attained and in the case of exceeding 15wt.%, drying velocity is undesirably low. By this method, the good hard alloy powder having only a small number of blow holes, and a small variation of particle size and being suitable to press forming, is obtd.

IPC: G06F21/10
Filed: 1984-11-30
Abstract: PURPOSE:To prevent a sly watching by stopping the channel selecting function when a specified counter for paid watching is overflowed. CONSTITUTION:In the controlling part of a terminal device, a down command is inputted to a shift register 7 through a decoder 4, compared 9 with the signal of a terminal address 8. When the comparison shows coincidence, a trigger signal is transferred to a command decoder 10 and counters 13 and 14. From the decoder 10, only when a specified command is furnished, a trigger signal is outputted so that the data stored in a register 11 is transferred to the counter 13. The operation cycle of the counter 13 is decided by the central station, and at the time when it overflows, the counter 14 operates. The counter 14 receives a gate signal from a discrambler 3. The counter 14 counts only when being scrambled by the image signal, and does not count when the normal image signal is being furnished. When the counters 13 and 14 overflows, a stop command is given to a PLL (phase locked loop) 15, and the channel selecting function of a converter 2 is stopped.

IPC: B23C5/10
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To reduce pitching further even when a previously quenched high hardness material is cut, and obtain the long service life by setting a rake angle in a cross section in the radial direction from the circular arc center of a ball blade to a negative value in the vicinity of outer peripheral cutting edges and to 0 or a positive value in the vicinity of a nose. SOLUTION: In a solid ball end mill composed of plural twisted outer peripheral cutting edges and a circular arc-shaped ball blade of an almost 1/4 circle continuously connected to these, when a rake angle in the vicinity of a nose is a negative value, large cutting resistance is applied, and useless force and heat are generated. On the other hand, in a part close to the outer peripheral cutting edges, a burden of useless force and heat is reduced, and it is useful for lengthening the service life.  Therefore, a part close to the outer peripheral cutting edges is set to a negative value of (-) 2 deg. to (-) 20 deg. with a position projecting most forward in the rotational direction as a reference, and strength of the cutting edges is strengthened, and a part close to the axis of a tool is set so as to have a part being a value of not becoming a negative of 0 deg. to (+) 10 deg., and convenience is offered for removal of chips, and cutting performance is enhanced.

Title: Hydraulic assisting type multiple disc clutch
Inventor: KATO MASAYA
IPC: F16D25/063
Filed: 1986-10-28
Abstract: PURPOSE:To reduce the operation stroke, by setting a biasing force of a control spring to be greater than that of a clutch spring, so as to let the clutch spring be flexed prior to the control spring. CONSTITUTION:A biasing force of a clutch spring 43 biasing a clutch pressure plate 27 is set to be smaller than a biasing force of a control spring 4 biasing the clutch pressure plate 27. Accordingly, an operational reaction force upon displacement of the pressure plate 27 is maintained at a substantially constant value owing to the characteristics of the clutch spring 43, and the constant reaction force is therefore applied to a lifter plate 39 at all times. Accordingly, before the lifter plate 39 directly abuts against the pressure plate 27, the clutch spring 43 is flexed to move the pressure plate 27, thereby reducing an operation quantity of the lifter plate 39.
