Title: Optical breaker
Inventor: KIN SHIYUNBAI
IPC: G02B5/04
Filed: 1994-03-31
Abstract: PURPOSE: To improve the light efficiency of a light projection system by including many specific reflection surfaces and the same number of slits as reflection surface in a light shielding device. CONSTITUTION: A light shielding device 30 includes a base 32, many, for example, three reflectors 34a to 36a, and the same number of slits as reflectors. Each of reflectors 34a to 36a consists of a glass block having a triangular section, and they have flat reflection surfaces 34b to 36b, where a light reflecting metallic material such as Al is depositied, on one side faces, and one faces are attached to the base 32 apart from one anther. Light from a non-point light source 11 is focused on reflection surfaces 34b to 36D of the light shielding device 30. Light reflected from them diverges along an optical path 14 and is converted to quasi-parallel rays by a second lens 40 and is thrown to, for example, m×n actuated mirror arrays 50. Each actuated mirror 54 corresponds to a picture element to be displayed and is controlled by the deformation of a coupled actuators 56.  Polarized reflected beams from respective mirrors 54 are focused and are partially projected through slits.

Title: Circuit quality monitor device
Inventor: HIROSE TSUGIHIRO
IPC: H04L1/20
Filed: 1987-03-18
Abstract: PURPOSE:To always monitor the quality of a circuit with no insertion of a specific signal for check of the circuit quality by performing the soft decision (multi-value decision) of the output of a demodulator to obtain reliability degree data on each information bit and to carry out statistic processing by an amount equal to an information bit string of prescribed length and deciding the circuit quality. CONSTITUTION:A soft deciding circuit 1 gives the soft decision (multi-value decision) to an analog output signal of a demodulator and outputs soft decision data. A bit reliability degree calculation circuit 3 converts the soft decision data into the reliability degree data to show the reliability degree of each information bit. A bit string reliability degree calculation circuit 4 performs the statistic processing of said reliability degree by an amount equal to the number of bits of the prescribed length and converts in into the reliability degree data of an information bit string of the prescribed length. A circuit quality deciding circuit 5 refers to said reliability degree data on the information bit string to decide whether the circuit quality higher or lower than a prescribed level and outputs the result of this decision. Thus it is not required to insert a specific signal for check of the circuit quality into the transmission data. Therefore, the circuit quality is monitored with no deterioration in transmission efficiency.

By detecting the load (weight of the chassis 1 plus load-carrying platform 2 plus movable load) directly, the calculating mechanism 40 judges whether movable load is proper or not or whether there is a danger of turning over of a vehicle due to one-side movable load or not based on the results of the detection, the weight of the chassis 1 and the load-carrying platform 2 which is stored in advance, or the total weight of the vehicle body when there is no movable load.  The calculating mechanism 40 displays the calculated value in a display device 41 and gives an alarm by an alarm unit 42 when the load exceeds the allowance value.

Title: Noise reducing circuit of video signal
Inventor: MURANAGA KOUTAROU
IPC: H04N5/21
Filed: 1983-04-12
Abstract: PURPOSE:To reduce the generation of a group delay time distortion to reduce the noise of a video signal by taking out high frequency components of the video signal with a high-pass filter and a cosine equalizer to eliminate noise components in an amplitude selecting circut and taking out low frequency components with a gauss filter. CONSTITUTION:A high-pass filter 2 is set to such low cut-off frequency that a horizontal synchronizing signal frequency fH can be attenuated sufficiently. A cosine equalizer 3 has a characteristic not to generate the delay time distortion,and its fequency characteristic shows a high band rise characteristic having a peak in a frequency fP indicated with 1/(2tau). Consequently, the frequency fP is set to, for example, about 7M Hz in the cosine equalizer 3, and high frequency components of the output signal of the high-pass filter are selected and taken out. The transmission of a low-level part is stopped by an amplitude selecting circuit 4 to reduce the noise which is a problem in sight. A gauss filter 5 shows a high band attenuating characteristic as known, and the generation of the group delay time distortion is very little. An adding circuit 6 adds said both signals in a proper level ratio, and the video signal which has the noise reduced is outputted from a terminal 7.
