Title: Binary coding device of video signal
Inventor: MORIMOTO HIROYUKI
IPC: G06T1/00
Filed: 1982-12-21
Abstract: PURPOSE:To extract only the effective pattern component to be detected out of a video signal by applying a superposed synthetic signal to a peak value holding circuit. CONSTITUTION:A superposed synthetic signal is applied to a peak value holding circuit PH to obtain at an output terminal 4 a waveform that traces along the voltage rise part of the superposed synthetic signal and holds the peak value obtained immediately before the voltage fall part. This waveform is approximately equal to the sum of the background component BG2 and the auxiliary ramp voltage. Therefore only the effective pattern signal component to be detected remains if the waveform (superposed synthetic signal at a terminal 3) is subtracted from the waveform (terminal 4) by a subtractor SB2. Thus a waveform emerges at an output terminal 5 of the SB2. This waveform is binary coded by a comparator CP on the basis of the threshold voltage of an output terminal 6 for threshold voltage. Then a binary coded signal of the waveform is obtained at an output terminal 7.

Title: Method and device for detecting reduction in tire air pressure
Inventor: NAKAJIMA MIKAO
IPC: B60C23/06
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To accurately detect a reduction in a tire air pressure even when an air pressure for a follower tire is reduced by determining a reduction in the air pressure of the follower tire by utilizing an actual vehicle turning radius calculated based on the slipping rate of a driving tire. SOLUTION: A turning radius RR for a follower tire is calculated based on each rotational angle speed of the follower tire detected based on the output of a wheel speed sensor (S4). On the other hand, a turning radius R(I) for a driving tire as a candidate for an actual vehicle turning radius is calculated based on a difference between each rotational angle speed of a driving tire corrected according to a distance from a turning center and the slipping rate of the driving tire (S7). Then, based on the turning radius R(I) for the driving tire, reduction reference turning radiuses R(I)1 and R(I)2 when each air pressure of the follower tire declines by 30% are calculated (S8). Then, based on a size relationship among the turning radiuses R(I)1 , R(I)2 and RR, a reduction in the air pressure of the follower tire is determined (S9 to S14).

Title: Painting method
Inventor: KATO SHINJI
IPC: B05D7/06
Filed: 1989-08-31
Abstract: PURPOSE:To prevent the generation of a recessed pit on a painting finish surface due to the moisture absorption or drying of a base material by forming a bottom coat layer to a base material and subsequently applying shape processing thereto before forming a top coat layer. CONSTITUTION:After a bottom coat layer 2 is formed to one surface and side surface of a base material to which rough processing is applied, for example, a hole 5 is formed to the base material 1 and a top coat layer 6 is subsequently formed to the surface of the bottom coat layer 2 and the inner peripheral surface of the hole 5. Since the exposed surface of the base material 1 is covered with the top coat layer 6 by this method, the base material 1 generates no moisture absorption or drying and a problem generating unevenness on a painting finish surface is not generated. Further, by making the film of the top coat layer 6 thin after shape processing is applied, a problem bringing about trouble in the assembling with a plastic part by the accumulation of paint at a corner part, that is, a problem caused by the lowering of shape accuracy is not generated.

Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To minimize the loss of data by detecting a signal informing start and end of data transmission and deciding the level of a busy signal depending on the level, and controlling transmission/reception, thereby sensing accurately a current communication state. SOLUTION: Transmitted serial clock(SCL) and serial data(SDA) are given to signal detection sections 10, 20, which sense a high level start signal OUT1 and a low level end signal OUT2. The high level start signal OUT1 and the low level end signal OUT2 are fed to a busy signal generating section 30, which generates a high level busy signal OUT. The busy signal OUT is fed in to a microprocessor, and it recognizes that a current communication network is in a busy state and controls the communication so that no data are transmitted. Thus, transmission of data in the way of communication between other auxiliary devices is prevented thereby protecting the data.
