Patent JP-S6365743-A (JP)
Title: Modulation circuit
Inventor: SHIBANO YOSHIZO
IPC: H04L27/22
Filed: 1986-09-06
Abstract: PURPOSE:To obtain a phase modulation signal with simple constitution by using two diodes subject to on/off control by a control signal to change the length of a transmission line. CONSTITUTION:The diodes 17, 18 are turned on/off in response to an output signal of a control circuit 3. In case of the off-state, an input signal from a conjugation terminal 11 is reflected at a grounded point of transmission lines 15, 16 and outputted from a conjugation terminal 12. In case of the on-state, since the line is short-circuited by a capacitor 19, the signal inputted from the terminal 11 is reflected at the diode connecting point of the lines 15, 16 and outputted from the conjugation terminal 12. Since the transmission line distance for the signal differs depending on the on/off state of the diodes 17, 18 in such a way, the phase is changed up to an angle theta only at the latter half of one time slot corresponding to the mark state of the transmission signal and restored to the reference phase at the latter half of the time slot and a phase modulation signal having the reference phase part only is obtained easily at the entire range of one time slot in the space signal.

Title: Thermal head substrate and manufacture thereof
Inventor: NAKAMORI TOMOHIRO
IPC: B41J2/335
Filed: 1987-08-25
Abstract: PURPOSE:To enable high-accuracy and high-speed printing to be performed with low electric power, by providing a substrate and a glaze layer provided on the substrate, and incorporating a porous glass powder and gel form porous silica into the glaze layer. CONSTITUTION:A glaze layer 12 comprising a porous glass powder 13 and gel form porous silica has excellent heat resistance and a low thermal conductivity. The glaze layer 12 has a high heat-insulating property because of the lower thermal conductivity, so that by only applying low electric power to a heat generating part, the surface temperature of the layer 12 can be brought to a predetermined temperature necessary for printing. The lower thermal conductivity of the glaze layer 12 enables a corresponding reduction in the thickness of the layer 12 while maintaining a sufficiently favorable heat-insulating property. Therefore, it is possible to reduce the heat capacity of the glaze layer 12 itself, whereby heat can be absorbed into the substrate 11 sufficiently rapidly after printing, which provide the function of rapidly lowering the surface temperature.

Abstract: PURPOSE:To clearly distinguish the type of collision, low-speed head-on collision or pole collision in particular, by providing a first integration means, integrating an output signal after corrected with a waveform correction means. CONSTITUTION:The waveform of the output signal of a G sensor GS is waveform-corrected so as to be attenuated from the peak value of the waveform in a given attenuation line CR with a waveform correction circuit S3.
