In accomplishing an LC-oscillation VCO circuit which is immune to frequency deviation and a frequency-hopping radio communication apparatus using the VCO circuit, a modulation semiconductor integrated circuit device is designed to control the LC-oscillation VCO directly with data to be transmitted thereby implementing the modulation and switch the carrier frequency for frequency hopping. The integrated circuit device includes a current adjusting circuit which varies the current value of a D/A conversion circuit for producing a control voltage of VCO in accordance with the carrier frequency so that the variation of a modulation control voltage of VCO has a characteristic that is opposite to the characteristic of modulation frequency deviation, thereby nullifying the modulation frequency deviation of VCO.

A solid state imaging device includes a plurality of photoelectric conversion elements arranged in an imaging area of a semiconductor substrate. Above each of the photoelectric conversion elements, a light-gathering microlens for gathering light on the photoelectric conversion element is disposed. Further, a microlens for shape inspection having the same shape as that of the light-gathering microlens is disposed outside the imaging area. A base pattern for inspection is disposed below the microlens for shape inspection. The shape of the microlens for shape inspection is inspected through observing an image of the base pattern through the microlens for shape inspection. A result of this inspection applies as it is to the light-gathering microlenses.

In a computerized numerical controller for a grinding machine, various grinding modes in which a plurality of portions on a cylindrical workpiece are respectively ground and plural sets of machining data each for use in machining a corresponding one of the workpiece portions are input by a manual data input device for storage in a memory device under the control of a data processor. For preparation of an NC program for the workpiece, the data processor first decides a grinding order in which the workpiece portions are successively ground, based upon the grinding modes and the machining data stored in the memory device. The grinding order is decided in accordance with a predetermined rule designed to decrease the number of dressing operations effected on a grinding wheel of the grinding machine. Then, the data processor automatically prepares a NC program based upon the decided grinding order and the machining data. In an NC operation, the data processor controls a pulse generating circuit in accordance with the NC program. Therefore, first and second feed devices responsive to feed pulses from the pulse generating circuit effect relative movement between a grinding wheel head and a workpiece support table in accordance with the NC program, whereby the workpiece portions can be successively ground in the automatically decided grinding order.
