Title: Plane optical waveguide
Inventor: YUI MASARU
IPC: G02B6/122
Filed: 1991-02-14
Abstract: PURPOSE:To prevent radiation loss from becoming excessive even when the radius of curvature of the curved part of the plane optical waveguide is made small by reducing the radiation loss at the curved part of the plane optical waveguide. CONSTITUTION:An electrode 3 is arranged along the outer periphery of the curved part of the optical waveguide part 2 formed by thermally diffusing Ti in the surface of an LiNbO3 crystal substrate 1 which is perpendicular to the optical axis.

Title: Data conversion system
Inventor: TAKEUCHI HIRONORI
IPC: G06F5/00
Filed: 1989-02-27
Abstract: PURPOSE:To reduce the amount of transmitted data by generating plural text data with plural input binary data and key data and compression the same successive data with a data compression identifier using a bit pattern which is never generated by conversion. CONSTITUTION:When the binary data is inputted from an input line 101 of the data, it is stored in a data storage circuit 4 and inputted to rows of the two-dimensional array of a data converting circuit 1 together with the two-byte key data from a key data generating circuit 2. The data converting circuit converts the respective rows into columns and the columns into rows to pass the converted data to a data compressing circuit 3. Then whether or not the same data succeed or not is tested to pass the data to a data transmitter 103 as it is when not. When the same data succeed, on other hand, the data are counted to generate the data compression identifier indicating the number of the same succeeding 1-byte data of the bit pattern which is never generated by a data converting circuit 1, and the identifier is passed to the data transmitter 103 while added behind one data, thereby sending the data. Consequently, the amount of transfer data decreases.

Filed: 1983-03-15
Abstract: PURPOSE:To facilitate detecting an abnormality in an idle switch, by a construction wherein a controlling signal is generated when it is detected that an idle switch is not operated even after the engine reaches a rotating speed indicating an idling condition. CONSTITUTION:When a signal (engine rotating speed Ne) outputted from a rotating speed sensor 3 and converted into a voltage proportional to the rotating speed by a frequency-to-voltage converter becomes not higher than a predetermined value (idle rotating speed N1), a checking signal at a high level is outputted from a timer circuit 5 for a period of time t1. When the opening of the throttle valve becomes not larger than an idle opening and the idle switch 1 is turned ON, a high-level signal is outputted through an inverter In, whereby a high-level signal is outputted from an AND circuit 2 for the period of time t1. In this case, when the idle switch 1 is in an abnormal condition and the output of the inverter In is at a low level, an output from the AND circuit 2 is at a low level, and a controlling signal indicating the abnormal condition is outputted from a micro-computer 6.

Filed: 1982-03-19
Abstract: PURPOSE:To linearize the control voltage-gain characterisics, by inserting a transistor to a diode and supplying the input signal voltage given from an input signal source to the emitter of a current source transistor. CONSTITUTION:It is possible to set the DC voltage of a signal output terminal 11 at a fixed level owing to the function of a dummy circuit 22 despite variations of control voltage VC since diodes D an D' are inserted to the emitters of transistors TRQ2 and Q2' having a base common with each other.

Then the signal current i0 flows to TRQ1 and Q2 with a shunt ratio which is decided by the control voltage VC, and output signal voltage e0 is generated by a signal current i1 which flows to a load resistance RL. The gain control characteristics of this circuit depend approximately on a linear equation of the current I1 of the TRQ1 and becomes linear.
