Title: Digital broadcast receiver
Inventor: SATO MAKOTO
IPC: H04N5/44
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To stably receive the digital broadcast wave of a specified channel while holding low noise characteristics irrelevantly to whether or not there is a disturbing wave of high signal level in an adjacent channel. SOLUTION: Signal levels of respective analog broadcasting channels are previously held as channel information in a channel information memory part 120 and when a specified channel is selected, a delay point control part 121 obtains the analog broadcast wave signal level of a channel adjacent to the specified channel from a channel information detection memory part 120 and selectively switches an RF-automatic gain control(AGC) control part 116 and an IF-AGC control part 115 at the delay point corresponding to the signal level. When the digital broadcast wave of the specified channel has a disturbing wave of high signal level, the delay point is made high to increase the tolerance to the disturbing wave, but when not, the delay point is made low to secure a dynamic range.

Title: Automatic equalization device for half rate code
Inventor: MITA SEIICHI
IPC: H04B3/06
Filed: 1989-09-27
Abstract: PURPOSE: To detect only the equalization errors occurring in a recording/ reproducing systems, to perform automatic equalization by selecting an odd number to a half rate code as the number of sampling at the time of setting tap coefficients of a transversal filter. CONSTITUTION: An equalization error Hj occurring in the recording/reproducing system is calculated in accordance with a formula I, by using a computer 10, and the value of a DA converter 11 is increased/reduced according to the result. A threshold of a comparator 8 is so controlled that it becomes the amplitude value of a required reproduced value ak' (the value obtained by discriminating and reproducing the value of a pulse train from an information source by a comparator 7). The threshold of the comparator 8 is varied in this manner to equivalently obtain the function of a gain adjuster. A converter having commercially available several tens or more quantization bits and operable with >=10MHz frequency is used as the converter 11.  As a result, only the equalization error occurring in the recording/reproducing system is detected with a high precision, without the effects of a gain adjustment circuit on a main line signal. This, automatic equalization is made possible.

Title: Carry circuit
Inventor: YAMADA KOUICHI
IPC: G06F7/507
Filed: 1983-12-27
Abstract: PURPOSE:To speed up the arithmetic by forming a carry circuit split into blocks having plural bits to miniaturize circuit components. CONSTITUTION:The carry circuit consists of the 1st stage block 7 and next stage blocks 11, 18. The carry output delay of the carry circuit has a value becoming larger sequentially from the 1st stage 7 to the next state and not negligible. In case of majority bits, when the relation between a delay tiem DELTAt and the output delay DELTAT is known in advance, blocks 7, 11 and 18 can have the large number of bits as they reach the end of stages. Thus, the block of the next stage can have block constitution more by one bit than the presenting block and the result of arithmetic is outputted at the same time even if the block of the n-th stage is increased by (n-1)-bit in comparison with the block of the 1st stage.

Title: Resin coating of surface grinder
Inventor: NAKAJO YOSHIHIRO
IPC: B24B37/12
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of rust on the upper and lower surface plates and an area adjacent thereto by coating the parts to be contacted with an abrasive, of the upper and lower surface plates with a resin. SOLUTION: When the flatness is impaired by the scratching of an abrasive pad mounting surface of the upper and lower surface plates 2, 5, the grinding work of a wafer is impaired, but by applying a resin coating 121 onto at least the abrasive pad mounting surface of the upper and lower surface plates, the impairing of the grinding work of the wafer can be prevented. The rust is generated by the abrasive when the abrasive is used in the grinding work, even though the upper and lower surface plates 2, 5 are not scratched, which also causes the impairing of the durability of the upper and lower surface plates 2, 5. But the durability can be also improved by applying the resin coating.  The rust by the abrasive is generated not only on the upper and lower surface plates 2, 5 but also on the bases 65, 120 supporting the upper and lower surface plates, so that the resin coating 121 is also applied onto the bases 65, 120.
