Patent JP-H01226217-A (JP)
Title: Oscillating circuit for proximity sensor
Inventor: KANDA YOSHIMI
IPC: H03B5/12
Filed: 1988-03-04
Abstract: PURPOSE:To set a threshold voltage to a considerably low level and to improve a distance to an obstacle and the linearity of the amplitude of oscillation by feeding back a current in an LC resonant circuit through a current mirror circuit so as to start oscillation and turning on and off a fourth transistor by means of the slight rise of the base voltage of a third transistor. CONSTITUTION:A current I3 flows which is decided by a variable resistance R2 for current adjustment in a transistor Tr7 in a current mirror circuit 11. The current is fed back to the LC resonant circuit 1 through the current mirror circuit 11 and oscillation starts. Since an emitter current flows in Tr9 when the terminal voltage of the LC resonant circuit 1 becomes negative, the emitting voltage comes below 0.6V, Tr8 is turned off and current feedback is stopped. Thus, Tr9 and Tr8 are alternatively disconnected by the voltage of the both terminals of the LC resonant circuit 1. When the base voltage of Tr9 slightly rises, a constant collector current flows in Tr8. When the rise of a saturation current for 10%-90% is displayed as a threshold Vref2, the threshold Vref2 shows the value of about 0.1V, for example.

Abstract: PURPOSE:To display with uniform lightness by expanding the picture element width of the character signal so as to be suited to an NTSC signal, and changing a signal level of a corresponding picture element based on the arranging state of a specific picture element string extracted from said expanded signal. CONSTITUTION:The picture element width of the character signal outputted from a personal computer, e.g., RS signal is expanded by passing the RS signal through a delay circuit 11. Then, the expanded character signal is inputted sequentially to a shift register 12 to output a 5-bit picture element string to a discriminating circuit 13. The circuit 13 discriminates the arranging state of the picture element of 1- level of each picture element string and outputs the result. That is, a picture element string having one or plural picture elements is extracted at least one of before and after the corresponding picture element at each picture element and the arranging state of the picture element having the specific signal level in each picture element constituting this picture element train is discriminated. A signal level changing circuit 15 changes the signal level of the corresponding picture element and controls an output transistor TR.

CONSTITUTION:A lowly heat-conductive friction material such as asbestos is fed to a mold of a predetermined shape, and irregularities are preformed by a press on the surface which is laminated with a highly heat-conductive friction material. During this preforming, the mold and the lowly heat-conductive friction material fed are preheated to about 80-120 deg.C to effect partial curing of the material. The material is then laminated with a highly heat-conductive friction material such as a metallic friction material, then pressed to a predetermined external shape, and heat-formed at a temperature of about 150-160 deg.C to obtain the purpose friction material for disc brakes. In this way, the bonding strength between the laminate surfaces can be improved because the irregularities are not damaged during the heat forming.
