Patent JP-S61248569-A (JP)
Title: Hetrojunction field effect transistor
Inventor: HIRAOKA YOSHIKO
IPC: H01L29/10
Filed: 1985-04-26
Abstract: PURPOSE:To obtain a high performance heterojunction FET, by sequentially laminating non-added GaAs having a broad band gap and n-GaAlAs through a p-GaAS layer on a semi-insulating GaAs. CONSTITUTION:A p-GaAs layer 2 is held between a semi-insulating GaAs substrate 1 and an undoped i-GaAs layer 3. Therefore, a barrier DELTAE is generated between the substrate 1 and the channel layer 3. When the concentration of the p-type layer 2 is 1X10<19>/cm<3>, DELTAE 0.7eV is obtained. The barrier prevents the intrusion of a large amount of electrons in the substrate in order to compensate for the decrease in electron density in a drain beneath a gate electrode 6 when a drain voltage exceeding a drain-current saturated state is applied. The barrier also limits the current to the channel 3 and substantially reduces the electron velocity component in the vertical direction with respect to the substrate. As a result the component in parallel with the substrate is increased, and the saturation value and gm of the drain current are increased. The degree of increase depends on the thickness of the layer 3, the height of DELTAE and the length of the gate. When the band gap of the layer 2 is larger than the layer 3, the higher effect can be obtained.

Title: Speed controller for dc motor
Inventor: OKADA YASUHIRO
IPC: H02P7/288
Filed: 1982-05-26
Abstract: PURPOSE:To enable to control the speed of a DC motor by maintaining the variation in the rotating speed of the motor to the environmental temperature regular even when a temperature sensitive resistance element having positive temperature coefficient is used so as to maintain the change in the temperature of load characteristic regular. CONSTITUTION:A constant current IS is flowed through resistors 11, 4 by a reference voltage source 5, resistors 6-8 and transistors 9, 10. Positive and negative input terminals of an error amplifier 12 become equal voltage state in the motor control state. Accordingly, Ea+RaIa=RTIT+RsIs (IT=Ia/K, where K means current distribution ratio) exists. Then, Ea=KaN (where N means the rotating speed of the motor 1, and Ka means a constant), and when RT=KRa is set, the motor rotates at constant speed without influence of the armature current Ia. Even if a temperature sensitive magnetic reluctance element is used as a resistor RT so as to compensate the temperature coefficient of the armature coil resistance Ra, the variation in the environmental temperature is made regular.

Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To provide a handheld optometer that reduces the errors of measuring angle information. SOLUTION: An angular position about a measuring axis is detected by an inclination sensor 210. A processor 201, in accordance with the result of detection by the inclination sensor 210, indicates on a finder 130 that there is an inclination. Also, the processor 201 corrects measurement data using the result of detection by the inclination sensor 210.

Inclinations in directions such that the detecting accuracy of the inclination sensor 210 is affected are detected by another inclination sensor 220. If the result of detection by the inclination sensor 220 exceeds a preset limit value, correction using the result of detection by the sensor 210 is not performed.
