Inventor: KONDO HIDETOSHI
IPC: H03F3/68
Filed: 1991-12-06
Abstract: PURPOSE:To achieve the wide band of a millimeter-wave radar apparatus. CONSTITUTION:A millimeter-wave oscillator is composed of the following: a quartz oscillator 1 which supplies a signal having a frequency of Fc; a pulse generator 2; a phase synchronization oscillator 3; and an up-converter 4 which generates a pulse signal having a frequency of Ft=(N1+N2) Fc.

Title: Clock for vehicle
Inventor: KONO KUNIYASU
IPC: G04R20/00
Filed: 1989-12-12
Abstract: PURPOSE:To enable correction of time in natural fashion by a time casting signal, by changing a pulse signal by a prescribed number of times in the direction of eliminating gradually an error detected by an error detecting means. CONSTITUTION:A time casting signal contained in a broadcasting wave received by a radio set 4 is detected by a time casting signal detecting circuit 24. An error detecting circuit 25 detects an error of the hour of a clock 1 detected by an hour detecting circuit 23, in respect to the time casting signal detected by the circuit 24, and outputs a signal of change of a pulse interval corresponding to the error to a pulse changing circuit 22. When the time casting signal is detected after the hour of the clock, for instance, a control circuit 20 changes the interval of a pulse signal inputted to a driving means, so that it is made longer by the number of times corresponding to the error than a regular pulse interval. When an hour hand indicates the hour after the detection of the time casting signal, to the contrary, the control circuit 20 changes the interval of the pulse signal so that it is made shorter by the number of times corresponding to the error between them than the regular pulse interval. By this method, the error is eliminated gradually as the time passes.

Title: Measuring apparatus for x-ray standing wave using photoelectron
Inventor: KAWAMURA TOMOAKI
IPC: G01N23/20
Filed: 1988-12-21
Abstract: PURPOSE:To enable measurement of an X-ray standing wave even in an ultra- high vacuum by using a rotary shaft having a microscopic rotary mechanism equipped with a differential exhaust mechanism and by rotating a sample precisely in the ultra-high vacuum. CONSTITUTION:An X-ray emitted from an X-ray source 16 is transmitted through an incident window 13 and led into a vacuum tank 10. The X-ray entering the vacuum tank 10 causes Bragg reflection due to a sample 12, and the intensity of photoelectrons radiated from the sample 12 on the occasion is measured by a detector 15. In order to confirm the occurrence of the Bragg reflection in the sample 12, the X-ray radiated from the sample 12 through an emission window 14 is measured by a scintillation counter 17. Since the sample 12 needs to be rotated with precision of 0.1 second or less in an X-ray standing wave method, a rotary shaft equipped with a differential exhaust mechanism is rotated in the vicinity of the Bragg reflection by a goniometer 11 for rotation having a microscopic rotation mechanism, and thereby measurement of an X-ray standing wave is executed. In this way, the X-ray standing wave can be measured even in an ultra-high vacuum.

IPC: G11B21/10
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To control the positioning of a magnetic head with high accuracy at a high speed by realizing a converting ability which is equivalent to that of a D/A converter having higher resolution than a used D/A converter has by outputting a manipulated variable which is computed from head position information obtained from the positional information of a magnetic disk so that the D/A converter may output a value having resolution higher tan its rated resolution. SOLUTION: Of the data A outputted to a 16-bit D/A converter in a CPU, a manipulated variable (u) is outputted to an 8-bit D/A converter and, at the time of expanding two bits of a 2 to the seventh bit and 2 to the sixth bit the remaining discarded data left in the CPU, four manipulated variables of 2 to the second are outputted at the timing obtained by quartering one sample period. The manipulated variable is decided based on the expanded data and outputted so that the average of the four manipulated variables may become equal to one controlled variable of a 10-bit D/A converter. Namely, when the expanded data are two-bit data, four-gradation data are generated. Therefore, it can be said that the resolution corresponding to 10 bits is obtained.
