Title: Disk device
Inventor: YAMAMURO MIKIO
IPC: G11B7/09
Filed: 1991-07-03
Abstract: PURPOSE:To prevent a data signal taken out from the cathode of a photodiode from being influenced by a tracking signal taken out from the anode by converting the detection current of an optical head to voltage only at a low band, by-passing a high frequency component and simultaneously converting it to voltage at a high band. CONSTITUTION:A tracking signal inclusive of a data signal and a header signal is outputted by using the current from photodiodes 8a, 8b by a preamplifier 36. That is, the anode side of the diodes 8a, 8b are converted to current/voltage by a low speed amplifiers 52, 53 for making the tracking signal. Further, the signal from the cathode is supplied to the inverted input side of a high speed amplifier 51, converted to the voltage and becomes the header signal and the data signal. At this time, since the high frequency current flows to the diodes 8a, 8b by capacitors C1, C2, the high speed current is taken out by a high speed amplifier 51.

Title: Carrier generator
Inventor: IHIRA KUNINOSUKE
IPC: H04L27/12
Filed: 1978-12-25
Abstract: PURPOSE:To realize a carrier frequency of a true value as to a random frequency by attaining access with address width made variable, by using ROM stored with sine- waveform data. CONSTITUTION:Address-width signal generator 2 generates an address width signal for generating a required carrier signal corresponding to modulated data from input terminal 1 and it is a cumulative value in accumulator 3. The address signal from accumulator 3 is subtracted by the same value by subtracters 4-7 in sequence, and code bits S1-S4, difference outputs, are inputted to encoder 11 to express positive code bits by ''0'' and negative ones by ''1''. Encoder 11, composed of ROM, converts them into three-bit codes C1-C3 corresponding to a combination of code bits and they are inputted to respective selectors 12-14. Here, since ROM15 uses only data corresponding to the 1/4 period of a sine wave, codes outputted by substracters are inverted into an address signal. Consequently, a carrier frequency of a true value can be obtained.

Title: Electronic component mounting board
Inventor: ASAI MOTOO
IPC: H05K1/18
Filed: 1995-06-29
Abstract: PURPOSE: To provide an electronic component mounting board where an insulation space can be easily ensured, and wiring troubles are lessened by a method wherein a linear pattern is so set in line width as to be smaller in a region relatively high in wiring density than in a region relatively low in wiring density. CONSTITUTION: Fine patterns 8 formed near the center of a board 1 and thick patterns formed on the periphery of the board 1 are linearly connected together with short tapered patterns 10, so that signal wires 2 are lessened in wire width W6 near the center of the board 1 where a wiring density is relatively high. Therefore, a space W7 between the fine patterns 8 can be secured, and an adequate insulation space can be comparatively easily ensured, so that wiring troubles easy to occur in a region of relatively high wiring density can be eliminated. Therefore, even if pads 3 are located close to each other, one or more signal wires 2 can be made between the pads 3, so that an electronic component mounting board of this kind can make finer constitution besides eliminating wiring troubles.

Title: Voltage-frequency converter
Inventor: SEKINE SATORU
IPC: H03M1/60
Filed: 1982-09-21
Abstract: PURPOSE:To obtain a voltage mean value output without adjusting the gain, by providing a frequency divider changed in interlocking with the change of a sampling time between a V/F converter and a counter. CONSTITUTION:A pulse train having a density proportional to an analog input voltage is supplied to the counter 3 by the V/F converter 1. An output of the counter 3 is sent to a register 4 at each sampling time set by a timer 5 and is reset. Thus, an output of a counter 4 corresponds to the mean value of the analog input voltage. Although the sampling time of the counter 3 is changed at a control circuit 7, since the frequency dividing ratio of the frequency divider 2 is changed at the same time, the average voltage value is obtained without adjusting the gain for the output of the register 4.
