Title: Optical device doped with erbium
Inventor: REONAADO SESHIRU FUERUDOMAN
IPC: H01S3/05
Filed: 1993-06-29
Abstract: PURPOSE: To raise natural radiation intensity from an active region and spectrum purity by making the thickness of an active layer doped with a rare earth element selected from elements of lanthanides series integral multiple of an operation half wavelength of a device and making a basic mode of a cavity resonate with a radiation wavelength of a rare earth element. CONSTITUTION: An active layer 13 is doped with ions of a rare earth element of lanthanides series of elements of atomic numbers 57 to 71. Dopant is introduced according to a material of an active layer by MBE, CVD or OMVPE when an active layer grows. An important condition is that the number of ions are restricted by the active layer 13. The thickness of the active layer 13 is an integral multiple of λ/2 where λ is operation of cavity or a radiation wavelength. The integer is selected from a range of 1 to 5 so that resonance cavity to natural radiation of rare earth dopant selected by combination with mirrors 12, 14 can be provided.

Title: Rotary compressor
Inventor: WATANABE TAKEJI
IPC: F04C23/02
Filed: 1988-06-27
Abstract: PURPOSE:To keep off any stirring of lubricating oil due to rotation of a lower bearing as well as to prevent any gaseous phase from being mixed in the lubricating oil by setting up an oil-level protector in an interspace between this rotating lower bearing and a suction port which feeds a sliding part with lubricating oil in the lower part of a closed housing. CONSTITUTION:When a stator 18 is energized with current, a permanent magnet 17 and a rotary yoke plate 16 both are rotated so that a lower bearing 15, a cylinder 11, an upper bearing 13, a vane 9 and a discharge valve 14 are all rotated as well. Accordingly, refrigerant gas inhaled in a cylinder chamber from a suction port 3 is compressed by a volumetric variation with rotation of the cylinder 11 and the vane 9, and it is discharged into a closed housing 19 from a discharge port 12. Lubricating oil 20 flows into an oil sump part 7 by way of an oil passage 6 from a suction port 5, while it flows into an oil groove 4 of a shaft 1. At this time, any stirring in the lubricating oil 20 due to air pressure or the like attendant upon rotation of the lower bearing 15 is kept back by an oil-level protector 21, thereby preventing any gaseous phase from being mixed in the lubricating oil 20.

Title: Optical disk and method for reproducing optical disk
Inventor: MATSUMOTO HIROYUKI
IPC: G11B7/24085
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To obtain high-level reproduction signals even from information by small projecting-recessed marks, by enlarging a step difference at an area of projecting- recessed marks where information is recorded beforehand, and forming a reflectance- changing film which changes its reflectance in accordance with temperatures. SOLUTION: A step difference of projections and recesses of the optical disk is set to be not smaller than 100nm which is larger than in a conventional disk. When a thin film is to be formed to a substrate 11 by sputtering or vapor deposition to obtain the step difference, sputtering particles are introduced from a slantwise direction. The particles do not reach the recesses at a vertical wall face and consequently a film thickness at the recesses becomes small. A heat capacity at the recesses is accordingly smaller than that at the projections. When reproduction beams are projected to read out recorded information, a temperature rise at a beam-condensing part is larger at the recesses than at the projections because of a difference of the heat capacities. A reflectance is varied by a difference of the temperatures.  For instance, if a material is used at a predetermined or lower temperature which is turned to amorphous when its temperature exceeds a crystallization, melting point, information can be read out by detecting the amount of reflected reproduction beams.

IPC: H04N7/18
Filed: 1992-06-18
Abstract: PURPOSE:To form the device making the higher burglar preventing effect by providing the video door phone device sending a response message only when a man falls on TV camera. CONSTITUTION:When a visitor presses a calling button 2, a signal makes a video recorder 13 and a sound recording device 14 to start. A human recognition device 15 senses the temperature of the body standing in front of a TV camera 9. When accepting an infrared-ray signal, the TV camera 9 equipped with, automatic focusing outputs a focal distance signal to sense a subject standing about 50cm forward the TV camera 9. By the pattern recognition of the picture signal, the figure, eyes, eyebrows, ears, nose or the like are sensed by a video recorder 10. Thus, when the recording of the human face is recognized, a start signal is sent from a signal line 21 to a response message generating device 16. The response device 16 makes a response for the first time, 'We are absent now. Message, please'. Thus, the burglar preventing effect can be improved.

Title: Single-gate nonvolatile memory cell and method for accessing the same
Inventor: PARRIS PATRICE M
IPC: H01L21/8247
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile memory cell with a simple structure which enables low-cost manufacture, and a method for accessing the memory cell for electrical erasure and programming. SOLUTION: A nonvolatile memory cell 10 includes a single insulating gate FET 11. In the FET 11, an electrostatic capacitance 24 of a parasitic gate-source capacitor is less than that of a parasitic gate-drain capacitor 26. This is attained by manufacturing the FET with an asymmetric structure or controlling the electrostatic capacitance of the parasitic capacitor through the bias of a terminal. The potential of a floating gate 12 is controlled by biasing a source 14, a drain 16 and a substrate 18. The cell 10 is programmed by moving charge to the floating gate via hot carrier injection. Erasure is performed by moving the charge from the floating gate via tunnel process. Reading is performed by detecting the conductive state of the FET.

Title: Sheet stacker
Inventor: ABE MASAHIRO
IPC: B65H31/34
Filed: 1982-09-16
Abstract: PURPOSE:To securely stack sheets conveyed, by providing a sheet movement stopper and an engaging member which is located in such a position that the distance between a rotary member and the position is smaller than the length of the sheets in the direction of its being delivered in. CONSTITUTION:When a sheet P has reached a rotary member 9, the front edge of the sheet is bitten in and pushed on the large-diameter part of the rotary member. The rear edge of the sheet P is brought into contact with the peripheral surface of the large-diameter part of the rotary member 9 and moved toward a return passage 7 and delivered in until the rear edge of the sheet comes into contact with an engaging member 10. Since the distance L between the engaging member 10 and the rotary member 9 is smaller than the length of the shortest sheets to be stacked, a V-shaped opening is certainly defined over the rotary member and the sheets already stacked. For that reason, even if sheets different in length are brought by conveyance in a mixed state, the edges of the sheets do not interfere with those of sheets already stacked. As a result, the sheets are neatly stacked.
