Title: End face light emitting type diode and manufacture thereof
Inventor: KANEKO TOSHIAKI
IPC: H01L33/10
Filed: 1986-07-18
Abstract: PURPOSE:To reduce the light quantity of a reflected light on an end face of an end face light emitting type diode to be returned toward an active layer thereby to enhance a threshold current necessary for a laser oscillation by obliquely forming at least one of end faces of an end face light emitting type diode. CONSTITUTION:When a current flows from an Au-plated film 10 to an Au-plated film 13, this current is constricted by a hole 7 to flow concentrically at a part of an InGaAsP layer 3 (active layer). A light of the quantity responsive to the current amount is generated in the layer 3. The generated light passes the layer 3, and is partly reflected on the end face. The end face is obliquely formed, and the reflected light according to a first law of reflection is not returned to the layer 3. Thus, since a current threshold necessary for a laser oscillation is enhanced, a linear relation between the current amount and the generated light can be widely maintained. An SiN film 14 of the thickness which satisfies nonreflecting condition is formed on the end face, and the quantity of the light emitted from the end face is increased to enhance the output.

Title: Dynamic semiconductor storage device
Inventor: TAKEMAE YOSHIHIRO
IPC: G11C11/408
Filed: 1982-09-29
Abstract: PURPOSE:To reduce greatly the degree of destruction of information on a non- selection cell by adding a simple circuit which clamps a non-selection word line at a non-selection level. CONSTITUTION:A transistor (TR) Q12 is turned on when a word line WL1 is selected, and therefore the non-selection word line WL2 is clamped at VSS through both terminals. As a result, the rise of potential is kept at a minute level for the line WL2 although the WL1 and N1 have the same change. This prevents the inversion of a cell MC2 opening a gate Q2. In the same way, a TRQ14 is turned on when the line WL2 is selected. Then the line WL3 is clamped at VSS. The effect of a clamping circuit CLP is clearly increased by dispersing the circuits CLP at plural areas in the extended direction of the word line, that is, by taking charge of just a part of the word line by the clamping circuit.

Title: Ultrasonic motor
Inventor: OGINO HIROYUKI
IPC: H02N2/00
Filed: 1994-07-22
Abstract: PURPOSE:To generate ideal traveling waves and to enhance the characteristic of a traveling-wave driven motor which is used for various kinds of uses. CONSTITUTION:An ultrasonic motor is driven in such a way that a plurality of piezoelectric vibrators are used and that traveling waves are generated. In the ultrasonic motor, the outside-diameter size of piezoelectric vibrators 6, 7 situated close to a side on which a stator 5 comes into contact with a rotor is made larger than the outside-diameter of piezoelectric vibrators located apart. At the same time, the ultrasonic motor has a shape which does not have an abnormal-shape part such as a cutout or the like on the outer circumference of the piezoelectric vibrators 6, 7. By this constitution, it is possible to obtain a motor in which admittance characteristic of the stator 5 becomes good, by which ideal traveling waves can be generated and which enhances an output characteristic.

Title: Rolling body
Inventor: KUSANAGI TAKASHI
IPC: A63H11/02
Filed: 1995-06-14
Abstract: PURPOSE: To enable a rolling body to roll in all directions without use of a motor, to enhance its durability, and to facilitate operation programming or the like, by operating one of plural driving elements which is selected by a command, in a direction in which it moves toward or away from the inner surface of an outer shell. CONSTITUTION: If, in an initial stationary state in which all solenoids 5 are not operating, the solenoid 5A, for example, is operated, a core bar 5Ab is projected toward and presses the inner surface of an outer shell 2. An inner shell 3 is entirely moved in the opposite direction by the reaction of the outer shell 2. Therefore, the center of gravity of the entire inner shell 3 deviates from the outer shell 2 in the direction of movement of the inner shell 3, and a rolling body 1 starts to roll in that direction. By selecting the appropriate solenoids 5 and operating them in sequence, the rolling element can be similarly moved in an optional direction.

Title: Image recorder
Inventor: SHICHIJO AKIRA
IPC: B41J2/44
Filed: 1984-08-18
Abstract: PURPOSE:To uniformize light exposure without increasing the period of time required for exposure and form images with uniform density and less blur, by repeating short-time exposure a preset number of times. CONSTITUTION:Light quantity correction information (number of times of exposure) for each LED constituting an LED array 13a is preliminarily stored in a ROM22. Synchronously with a scan clock, a scan clock circuit 14 designates to the ROM22 a storage address of the light quantity correction information for the LEDs to be driven, and causes the information to be outputted from the ROM22. A controlling circuit 21 takes the logical sum of a picture signal inputted through a terminal 11 and the light quantity correction information inputted from the ROM22, and selectively outputs a picture signal required for exposure. Exposure is repeated a larger number of times with light-emitting elements having lower light-emitting capacity, and is repeated a smaller number of times with light-emitting elements having higher light-emitting capacity, thereby forming an image on a photosensitive selenium drum 15a through an optical system 13b. Accordingly, light exposure is uniformized with little increase in the period of time required for exposure, and images having uniform density and free of displacement are obtained.

Title: Rush current avoiding circuit
Inventor: MIZUNO TOSHIO
IPC: H02M7/12
Filed: 1991-07-12
Abstract: PURPOSE:To avoid a rush current caused by a sudden cut-off of an AC input voltage. CONSTITUTION:The rectified output voltage of a rectifying circuit 1 is applied to a load 9 and an output capacitor 2. A rush current produced by closing a power supply switch 10 is avoided by a current limiting resistor 3. When the terminal voltage of a capacitor 6 charged through a resistor 5 exceeds a predetermined value, a switching device 4 is turned to short-circuit the current limiting resistor 3. If an input AC voltage is cut off, a transistor 8 is turned on by the cut-off detection signal of a cut-off detecting part 7 and the discharge time constant of the capacitor 6 is made to be approximately zero to make the terminal voltage of the capacitor 6 decline rapidly. As the switching device 4 is turned off by the decline, when the input AC voltage is recovered, a rush current can be avoided by the current limiting resistor 3.
