Title: Temperature compensating the voltage controlled piezoelectric oscillator
Inventor: ARAKI YOSHIAKI
IPC: H03B5/32
Filed: 1989-02-01
Abstract: PURPOSE:To compensate the temperatures despite the change of the temperature characteristics of an oscillation frequency by connecting a temperature compensation circuit also to the other terminal where the frequency control input voltage of a variable capacity element of a Colpitts type voltage controlled oscillator is applied. CONSTITUTION:The frequency control input is connected to the anode of a variable capacity diode 5 forming a Colpitts type voltage controlled piezoelectric oscillator together with the output of a temperature compensation circuit 10 connected to the cathode of the diode 5 respectively. The voltage higher than the anode side voltage is supplied to the cathode of the diode 5, therefore the oscillation frequency of the voltage controlled piezoelectric oscillator is increased with the increase of the output of the circuit 10. While the oscillation frequency of the oscillator is reduced with output reduction of the circuit 10. In such a constitution, the output changing rate of the circuit 10 can be optionally set against the change of the ambient temperature. Thus it is possible to compensate the temperatures even though the temperature characteristics of the oscillation frequency are changed by the variance of the temperature characteristics of a piezoelectric vibrator 1 and the diode 5.

Title: Surface potential sensor element
Inventor: IKUSHIMA HIROSHI
IPC: G01R29/12
Filed: 1985-02-07
Abstract: PURPOSE:To create the same function as when two independent sector-shaped surface potential sensor elements are used, by mounting one each of a double- layer structural body on the tips of both legs of one piezo-electric tuning fork so as to function as surface potential detecting electrodes different in the distance from a surface to be measured. CONSTITUTION:Right and left highly conductive films mounted on the tips of both legs of a piezo electric tuning fork differentiate the gap (d) up to the open face W of a common line of electric force introduction port from each other. As the movement of right and left legs of the piezo-electric tuning fork is opposite in the phase from each other while they act in the same phase when receiving the line of electric force to accumulate or release electric charge, they are regarded as equivalent to two conventional sensor elements in the detection of the surface potential, only if the electrode areas thereof is equal to each other. Thus, when two amplification circuits for detection signals are incorporated or provided externally corresponding to right and left electrodes thereof, only one independent piezo-electric tuning fork and a shield case can provides the work equivalent to that of two pieces of the conventional sensor elements.

Title: Optical memory element
Inventor: BAN KAZUO
IPC: G11B7/24035
Filed: 1989-01-30
Abstract: PURPOSE:To enable recording, reproducing and erasing based on PHB phenomenon which occurs significantly even at high temp. by forming a specific optical memory layer in a polymer matrix and constituting the polymer matrix of three-dimensional crosslinking polymers. CONSTITUTION:Informations are recorded, reproduced and erased by irradiating a recording medium, namely, an optical memory layer with light. The recording medium is constituted by dispersing in a matrix of three-dimensional crosslinked org. compd. which is photochromic or causes rearrangement of hydrogen atoms by laser light. By this method, thermal dynamics of matrix molecules 4 around a guest molecule 3 are limited and the local structure around the guest molecule 3 remains even at high temp., so that the stability of the PHB hole in the absorption spectrum caused by laser light is more stabilized against temp. Thus, recording, reproducing and erasing based on the PHB phenomenon can be performed at high temp.

Abstract: PURPOSE:To reduce a leakage current during a pinch-off by controlling a drain current from a source to a drain by using a gate electrode composed of at least two kinds of metals. CONSTITUTION:In a field-effect transistor whose gate length is short, an active layer 5 used to form a current channel is formed on a high-resistance substrate 6 by using an ion implantation method or an epitaxial method.

By this setup, the inclination of a cross section of a depletion layer 7 due to a position in the source-drain direction to be caused during an operation of a field-effect transistor is corrected; it is possible to eliminate a leakage current as far as possible during a pinch-off of a drain current.
