Filed: 1994-11-24
Abstract: PURPOSE: To save labor for a worker who is preparing a machining program so as to enhance the working efficiency by obtaining an offset shape from machining shape data and offset data so as to compute a turning angle of a C-axis in a block. CONSTITUTION: A turning angle computing part 22 computes coordinate values of a cross point of a machining shape at a boundary between a block and a block before the block, and coordinate values of a cross point of a machining shape at a boundary between the block and a block next to the block. Further, coordinate values of a cross point of an offset shape corresponding to the cross point of the machining shape can be computed from the offset shape obtained by an offset shape computing part 21. Straight lines connecting between the coordinate values of the cross point of the machining shape and the coordinate values of the cross point of the offset shape are obtained, and a turning angle of a C-axis is obtained from an angle between two straight lines. Thereby, thus obtained turning angle is added to a moving instruction value of the block.

Title: Musical tone synthesizer
Inventor: NAKANISHI MASAHIRO
IPC: G10H7/00
Filed: 1989-12-04
Abstract: PURPOSE:To realize the change of a tone due to that of a driving input point by inputting data read out of first and second storage parts to a data working part, respectively, and sending an vocalization instruction from a table part to first and second adders, and tone height and the tone from a word length instruction part which instruct word length to first and second address generating parts, respectively. CONSTITUTION:Driving data sent from the table part 1, after being inputted to the first and second adders 92, 93, are stored in first and second storage parts 11, 12, respectively, and after being delayed for certain time, it is worked at first and second data working parts 95, 98, and is returned to the first and second adders 92, 93. A desired musical tone can be obtained by repeating such operation. Also, it is possible to realize the change of the tone same as that of the tone due to the change of the driving position of the string of a stringed instrument by controlling the number of stages of the first and second storage parts 11, 12 with the first and second address generating parts 13, 14 and the word length instruction part 15. Thereby, since it is enough to control only two storage parts, the change of the tone can be realized with simple configuration.

Title: Demodulator
Inventor: UEDA HIROYUKI
IPC: G11B20/14
Filed: 1993-12-15
Abstract: PURPOSE:To improve the data read rate by switching a pulse frequency received by a counter with an external control input so as to switch the discrimination coefficient of the demodulator. CONSTITUTION:A variable frequency divider 9 being a 2nd frequency divider applies 1/n (n is a natural number) to an output pulse of a pulse oscillator 1. Various frequency division ratios are selected by an external control input terminal (s) (n is variable in a range of 1/2m<n<m). A second counter 5 down counters the output of the divider 9. Since the frequency of the pulse signal given to the counter 5 is made variable by the frequency divider 9 in this way, the pulse width of a discrimination signal (e), that is, a discrimination coefficient n/m is selected by the external control input terminal (s). Thus, a read rate of data is enhanced by adjusting the discrimination coefficient n/m for a card whose data are hardly read because of locally different recording frequencies and reading the data again.

Abstract: PROBLEM TO BE SOLVED: To limit output to a driving wheel and safely and surely run to an aimed place, even when abnormality occurs at a driving system or a control system and normal transmission of motive power to a driving wheel cannot be carried out. SOLUTION: When abnormality occurs, in at least an engine system and at the same time abnormality occurs in a motor (A) controller system, the engine is stopped by an injector power-supply stopping signal (S152), and each control power for first and second motor is turned off to stop the first and second motors (S153, and S154) and stop the vehicle. Further, a contactor is turned off by a contactor control signal to cut off the motor (A) controller and the motor (B) controller from as battery (step 155). An abnormal-time control signal for the motor A controller and the motor B controller is made as a normal-time control signal, and the normal-time control is put in a state of implementation (S156, and S157).  Then, a control signal for turning off a lock-up clutch and a gear ratio command for making a CVT (belt-type continuously variable transmission) in a given transmission ratio are fed to an T/ M-ECU (step S159), so that safety is ensured.

Title: Production of highly abrasion-resistant aluminum alloy
Inventor: KIM JUN-SU
IPC: F02F1/08
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To obtain an aluminum alloy having high wear resistance and good mechanical properties by dispersing silicon particles on only required part for wear resistance of a preform and permeating the molten aluminum alloy into the preform under a specified pressure.  
     SOLUTION: Preform is manufactured so as to disperse silicon particles on required part for wear resistance, e.g. inner wall of cylinder block The molten aluminum alloy is permeated into the preform under a pressure of 20-200 MPa. In this case, if the pressure is < lower limit, it is impossible to get strong composite materials because the permeation state is unstable, on the other hand, even if the pressure is > upper limit, no effect of elevating the pressure is brought about. As preform, the one containing 12-54 vol.% silicon particles with 5-90 μm diameters is preferable. If the diameter of particle is > upper limit, there are problems in mechanical properties e.g. in tensile strength, and if it is < lower limit, there are problems in the manufacture of the above preform and the permeability of the molten alloy.
