Title: Frame synchronizing signal detection circuit
Inventor: NAGASHIMA KENSUKE
IPC: H04L7/08
Filed: 1989-07-17
Abstract: PURPOSE:To detect a frame synchronizing signal and its N-bit error value at the time of transmitting at a high speed by using the serial-parallel conversion output of received data as the address of a ROM. CONSTITUTION:Serial-parallel reception data 60 from a receiver 10 is converted to parallel data of 16 bits synchronized with a reception clock 50 with a serial- parallel converter 20, and also, is shifted bit by bit synchronizing with the clock. The data goes to the address of the ROM 30. In the ROM 30, the data is written so that only output of 17 parts of the frame synchronizing signal and its one-bit error value in total can be changed. Therefore, when the parallel data 70 of 16 bits which goes to the address and changes bit by bit coincides with the frame synchronizing signal or its one-bit error value, the output is changed during one clock and the detection of the frame synchronizing signal can be performed.

Title: Method and system for monitoring fire using multiple transmission
Inventor: FUJIKI HITOSHI
IPC: G08B26/00
Filed: 1989-07-17
Abstract: PURPOSE:To make design simple and to reduce cost by providing a fire accident receiver and a repeater, converting mutually received signals to a prescribed level, returning the signals, reducing the function of the repeater and concentrating processing function onto the fire accident receiver. CONSTITUTION:The transmission switch signals of multiple transmission levels designating a repeater address are transmitted from a fire signal machine 1 through a multiple signal line l to a repeater 2 by a polling system. In the repeater 2, a monitor signal is converted to the level corresponding to a signal line l3 and sent to a sensor SA. In the sensor SA, the returned signal is converted to the multiple transmission levels again by the repeater 2 and returned to the receiver 1. The receiver 1 decodes this returned signal and senses the announcement of the sensor SA connected to the line 3 of the repeater 2. Then, the repeater 2 is equipped with the function to execute the level conversion only and the receiver 1 improves the signal processing function. Then, the announcement of the sensor SA without setting the address can be detected. Thus, the design is made simple and the cost is reduced.

SOLUTION: A casing 1 is divided into independent casing blocks 20a-20e, and chambers 3a-3e separated by each casing block are provided with a filter and a heater 4, respectively. The filter members 5-1, 5-2 of the filter capture soot and dust, and the filter is regenerated by stopping the circulation of an exhaust gas in a regeneration chamber and heating the heater 4. The thermal expansion of the casing block in a regeneration phase is larger than the other casing blocks. However, a stress brought to the unit area of an interface due to a thermal expansion difference does not generate between the casing blocks, i.e., the casing.

Filed: 1992-07-10
Abstract: PURPOSE:To prevent a fog due to malfunction by detecting accurately the operation such as panning and inhibiting the drive of a focus lens when panning is detected. CONSTITUTION:Panning is detected based on a change in a sharpness signal and a change in iris information. In this case, the device receives a sharpness signal S and iris information F respectively (S61), a difference ds between the sharpness signal S and a sharpness signal SP at a focus is calculated and its absolute value ¦ds¦ is obtained (S62). Moreover, a difference dF between the current iris F and an iris Fp at a focus is calculated and its absolute value ¦dF¦ is obtained (S63). When panning is detected, the focus lens is kept in the halt state regardless of the presence of a change in the sharpness signal and when no panning is detected, a change in the object is detected from a change in the sharpness signal and whether or not restart is to be implemented is discriminated.
