Title: Spectroscope
Inventor: KASHIMA TAKUZOU
IPC: G01J3/06
Filed: 1986-03-03
Abstract: PURPOSE:To calculate the wavelength of dispersing light and to perform spectral diffraction within a short time with good accuracy, by calculating a wavelength value on the basis of the angle of rotation of an element by conversion or operation due to a table. CONSTITUTION:The angle of rotation of the wavelength data DA stored in RAM 30 corresponds to the count value of a counter 28. Therefore, the wavelength data DA corresponding to the angle of rotation of a dispersing element 12 is outputted to a DA converter 42. This data DA is converted to an analogue signal by the converter 42 to be inputted to the X-terminal of an oscilloscope 24 while a high frequency component is removed from said analogue signal by LPF 44. Dispersing light having the wavelength corresponding to the data DA is incident to a light receiver 18 to be converted to a voltage signal which is, in turn, amplified by an amplifier 20 to be inputted to the Y-terminal of the oscilloscope 24. The frequency spectrum of incident light PA is displayed on the picture of the oscilloscope 24. Further, when the output voltage of the converter 42 reaches reference voltage or more, a display apparatus 50 displays that the intensity of dispersing light is equal to or more than a predetermined level.

Title: Rotation detector
Inventor: HASHIMOTO TOSHIO
IPC: H02K29/14
Filed: 1993-03-04
Abstract: PURPOSE:To prevent magnetism sensitive elements from being affected by leakage magnetic fluxes from rotor magnets. CONSTITUTION:Magnetism sensitive elements 31 are printed on a substrate 32 formed of an insulating material. The substrate 32 is fitted to a bottom plate 21 by means of a supporting section 33 formed of a magnetic material. As a result, the elements 31 are prevented from being affected by leakage magnetic fluxes from rotor magnets 11, because most of the leakage magnetic fluxes pass through the supporting section 33. Therefore, the rotational speed of a capstan motor 1 can be accurately detected, since the element 31 can accurately detect the variation of the magnetic field of an FG magnet 13. In addition, the constitution of the detector can be simplified.

Title: Inverter device
Inventor: ISHIZUKA TOMOTSUGU
IPC: H02M7/483
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent the AC current of a snubber circuit connected in parallel with a turned-off switching element from caused to flow in switching elements which continue to be turned on, and from increasing the loss, when a switching state changes in the case of a multi-level inverter device. SOLUTION: When a second switching element continues to be turned on, a third switching element 5 is turned off, and a first switching element 3 is turned on in an inverter device in which the first to fourth switching elements 3 to 6 are connected in series, the gate current or gate voltage of the second switching element 4 is made to increase for given period of time, when the first switching element 3 is turned on. This causes the charging current of a snubber circuit connected in parallel with the turned-off switching element to flow, which in turn makes it possible to suppress a transient on-voltage which occurs in the switching elements maintaining an on-state, thereby reducing loss.

Title: Field effect transistor
Inventor: ITOU TOMOHIRO
IPC: H01L29/80
Filed: 1983-03-17
Abstract: PURPOSE:To enable to obtain good Schottky junction and high withstand voltage by making a structure wherein the band gap width of an N type semiconductor operating layer is continuously increased from the interface between a substrate toward the surface. CONSTITUTION:The N type AlxGa1-xAs operating layer 12 is grown on the semi-insulation GaAs substrate 1 so that the molar ratio (x) of the AlAs continuously reduces from the surface toward the substrate interface. Next, N<+> contact layers 13 are formed, and further a gate electrode 3, source electrode 4, and drain electrode 5 are formed. By such a structure, electrons run at the high electron mobility almost in the GaAs because of running in the close neighborhood of the substrate interface operating in normal operated state. On the other hand, the barrier height of the Schottky gate slightly increases more than that of the GaAs, and further the band gap width becomes large in AlGaAs. Therefore, the yeidling phenomenon at the Schottky gate interface is extremely difficult to occur, thus enabling high withstand voltage and high performance.

Title: Preventing mechanism of double recording
Inventor: FUKUDA TADATOSHI
IPC: G11B19/04
Filed: 1983-03-17
Abstract: PURPOSE:To prevent the double recording of an electronic camera by permitting the recording operation when it is detected that a counter driving hub is fitted to a counter ring with energizing of a spring. CONSTITUTION:The disengaged state of a counter driving hub 23 is detected by a sensor 26. When an unrecorded cartirdge is set, pawls of the driving hub 23 and engaging grooves 5b, 5c, and 5d of a ring 5 concide with each other, and therefore, the engaged state is set immediately. However, when a cartridge where information is laready recorded partially is set, the driving hub 23 is depressed to allow a reflective ring 27 face the sensor 26, and the obtained sensor output closes the output gate of a recording circuit, and a head access motor is driven. When the driving hub 23 turned by driving of the motor has pawls matched to engaging grooves of the ring 5, the driving hub 23 rises to be engaged with the ring 5, and therefore, the sensor output is deenergized to open the gate of the recording circuit, and the motor is stopped when outputs of rotation detecting means 19 and 20 are generated, and the recording holding state is set. Consequently, double recording is prevented.
