Title: Electrically ersable programmable memory cell
Inventor: AREN TEII MITSUCHIERU
IPC: H01L27/115
Filed: 1988-11-29
Abstract: PURPOSE: To obtain the structure of a memory cell and its array with high reliability by placing an erasure window apart remotely from an active region of a transistor(TR) of the memory cell. CONSTITUTION: Axes A, B, C and D are extended perpendicularly from a side 14 of a substrate 16 as shown in broken lines. Furthermore, they are in crossing with the substrate 16 as shown in column lines 12 and extended through floating gates 20a, 20b, 20c and 20d of a floating gate layer 20. A lateral cross section of a path 28 is almost formed to be a square, and a width of each side of the square is set almost to an interval D7. Moreover, a tunnel oxide insulation layer 32 is in existence in each path 28, lies on the floating gate 20 and is extended laterally within a limit decided by a side wall insulator 30. A poly layer 34 is extended in a path 29 and in contact with insulators 31, 32. Thus, the insulator 32 acts like an erasure window. Moreover, the insulator 32 assists tunneling.

Title: Dehydrogenating reactor
Inventor: ITO NAOJI
IPC: C07C5/367
Filed: 1986-12-18
Abstract: PURPOSE:To obtain a device to reduce hydrogen concentration in a reaction chamber and to promote dehydrogenating reaction, by at least partially constituting a partition wall of a reaction chamber packed with a dehydrogenating reaction catalyst made of a hydrogen permeable material and taking out formed hydrogen to the outside of the reaction chamber. CONSTITUTION:In a reaction device consisting of an inner pipe 1 and an outer pipe 2, a raw material is fed through a line 4 to a reaction chamber A packed with a dehydrogenating catalyst and a reaction product is taken out through a line 5. An inert gas is sent through a line 3 to an empty part B and extracted through a line 6. Since hydrogen formed in the reaction chamber A is permeated through a peripheral wall 1 made of a hydrogen permeable material and sent to the empty part B and taken out to the outside of the system, hydrogen concentration in the reaction chamber A is extremely reduced to promote dehydrogenating reaction. Pd metallic film, an alloy film of Pd and gold, silver, etc., inorganic porous film, etc., may be used as the hydrogen permeating material.

Title: Laser
Inventor: OTSUTOO BIIRAA
IPC: H01S3/036
Filed: 1990-11-09
Abstract: PURPOSE: To obtain a high output compact laser by providing a plurality of partial sections, and optical coupling sections to be coupled each other through a deflection mirror and arranging the partial parts only in the radial direction with respect to a common center. CONSTITUTION: As shown by an arrow 18, the beam path of a resonator 1 starts from an end mirror 16 and passes through two partial sections 4 arranged linearly while intersecting the center of beam 6 before being deflected from a mirror 10 along an optical coupling section 12. It is then reflected again clockwise by an angular interval α on the mirror 10 and extends along other two partial sections 4 while intersecting a new center beam 6. The regressive pattern continues until it reaches a beam transmitting resonator mirror partially. A laser medium is excited only in the region of partial sections 4, 4' and not excited in the region of the section 12. Since thermal expansion takes place in the radial direction at the time of laser excitation, the angular interval αis varied only slightly thus eliminating the need of adjusting the resonator beam.

Title: Cmos voltage standard/buffer circuit
Inventor: TEIMOSHII BUI KARUSOFU
IPC: G05F3/30
Filed: 1989-11-21
Abstract: PURPOSE: To make a CMOS voltage reference circuit quickly respond to a transient load applied to an output node providing a band gap circuit, a power supply noise rejection circuit, and a unity gain buffer in the voltage reference circuit and reducing the output impedance of a reference voltage source. CONSTITUTION: The output of a differential amplifier 140 is connected to the noninverted input of an operational mutual conductance amplifier 141. The output of the amplifier 141 is connected to its own inverted input and placed in the feedback loop of the differential amplifier 140. Therefore, the low output impedance of the amplifier 141 is further reduced at the rate of the open loop voltage gain of the operational amplifier 140. Therefore, a buffer circuit 25A becomes an extremely low output impedance as a whole and, at the same time, the speed of the response of the circuit 25A which acts against a transient voltage applied across the output of the circuit 25A is increased.

Title: Noise suppressing circuit
Inventor: TODAKA JUNICHI
IPC: H03K17/16
Filed: 1992-11-13
Abstract: PURPOSE:To suppress overshoot and undershoot by suppressing a switching noise generated in the non-saturated area of output potential from a noise suppressing circuit. CONSTITUTION:The noise suppressing circuit has an inverter 1, diodes 2, 5, p-channel type MOSFETs 3, 6, n-channel type MOSFETs 4, 7, and delay circuits 8, 9. When the potential of a point (a) is switched from a low level to a high level, the potential of a point (b) becomes >=Vf of the diode 5 and the diode 5 is turned on. Since the drain electrode of the diode 5 is grounded, the potential of the point (b) is dropped. At the time, a delay circuit 9 transmits the potential (high level) of the point (a) to the gate electrode of the MOSFET 7, which is turned on. Thereby a current flowing into the route of the MOSFET 4 and the diode 5 is allowed to flow into the route of the MOSFETs 4 7 and the potential of an output terminal 10b is stabilized at a low level.
