Title: Semiconductor device
Inventor: KUSHIDA TOMOYOSHI
IPC: H01L29/749
Filed: 1986-04-07
Abstract: PURPOSE:To simultaneously satisfy three conditions of a high speed switching, a low forward voltage drop and a high main electrode blocking voltage by forming local regions having relatively short charge carrier life on the vicinity of a gate region and a region depleted eventually in a main current interrupting step to an eventually depleted region. CONSTITUTION:A cathode region 11 and an anode region 12 made of opposite conductivity type high impurity density regions, a low impurity density region 14 formed at part between the regions 11 and 12, and a gate region 13 formed near the region 11 for controlling a main current are formed. in such a semicon ductor device, local regions 16, 15 having relatively short charge carrier life are formed on a region near the region 11, a region eventually depleted in a main current interrupting step and an eventually depleted region of the region 14. For example, after a P<+> type anode region 12, a P<+> type gate region 13 and an N<+> type cathode region 11 are respectively formed on an N-type silicon substrate, a photon beam is emitted from both side surfaces of an element to form regions 15, 16, thereby forming a static induction thyristor.

Title: Use limit sensor for friction brake
Inventor: NAGARA HIROAKI
IPC: F16D66/00
Filed: 1986-04-07
Abstract: PURPOSE:To detect the use limit brought by vapor lock of working fluid and fade of a friction pad as well as the use limit brought by abrasion of the friction pad by providing a fixed electrode member with an auxiliary electrode member made of shape memory alloy. CONSTITUTION:When either vapor lock of working fluid or fade of a friction pad 4 occurs, temperature rises. An auxiliary electrode member 26 made of shape memory alloy is expanded to be in contact with the inner surface of a movable electrode member 25, so that an indication lamp is turned on electricity to distinguish the use limit of a friction brake. Further, when the abrasion loss of the friction pad 4 reaches a designated amount, the auxiliary electrode member 26 is brought into contact with an inward flange portion 28 even in the winding state by movement of the movable electrode member 25 caused by a spring 24, so that the indication lamp 30 is turned on electricity to distinguish the use limit. Accordingly, the use limit can be reliably detected and furthermore the friction brake can be used repeatedly by replacing the friction pad 4.

Filed: 1983-05-09
Abstract: PURPOSE:To obtain a fluorescent lamp which gives the same optical color, freshness and whiteness as a fluorescent lamp of the three-wavelength-range emission type by using a phosphor film consisting of a calcium halophosphate having a specified chromaticity range and yttrium oxide activated with europium. CONSTITUTION:A phosphor film is obtained by mixing a calcium halophosphate phosphor activated with antimony and manganese with a yttrium oxide phosphor activated with trivalent europium. When the above calcium halophosphate is used in a lamp, its chromaticity point is located on a line connecting the center (x=0.330, y=0.361) of a circle and the center (x=0.330, y=0.366) of a circle in oblique xy-coordinates, used to deform the MacAdam's deviation ellipse into a circle, and located in a circle having a diameter of 5SDCM. For instance, in order to adjust the mean color rendering index to not less than 75: addition of 0% of yttrium oxide activated with europium is necessary for a calcium halophosphate phosphor located at point (S) in the figure; addition of about 5% is necessary for that located at point (T); and addition of about 10% is necessary for that located at point (U).

Title: Photodetector
Inventor: OTSUKA RIE
IPC: G01J1/44
Filed: 1985-04-16
Abstract: PURPOSE:To expand the measuring range of a photoelectric converting element by detecting an output from the photoelectric converting element, and making the incident light on the photoelectric converting element variable. CONSTITUTION:The light which has transmitted through a light depreciating element 5 and has been made incident on a photoelectric converting element 1 is inputted to a comparator 4 through an amplifier 2. In this case, the comparator 4 having a hysteresis characteristic compares an output voltage of the amplifier 2, and a reference voltage of a reference voltage generator 3, generates an H level signal in case when the output voltage from the amplifier 2 is lower than the reference voltage, and generates a signal of an L level in case when said output voltage is higher than the reference voltage. When the signal of an L level has been generated, the transmittivity of the light depreciating element 5 is lowered in order to limit the incident light on the photoelectric converting element 1, and also switches a feedback resistance by interlocking an amplification degree changeover switch 6. In this way, in case when the light of a range being out of the linearity has been made incident, an output of the amplifier 2 of the photoelectric converting element 1 is detected, and the incident light is limited electrically, therefore, the measuring range of the photoelectric converting element 1 can be expanded.

Filed: 1981-05-27
Abstract: PURPOSE:To allow accurate measurement of air fuel ratio with cheap constitution, by changing the air fuel ratio periodically, and detecting the ratio of the output inversion time of the oxygen sensor installed in the exhaust system to the one cycle. CONSTITUTION:When the fuel injection equipment 2 which is installed to the suction manifold 7 being connected to the Otto cycle engine 8 is controlled by electronic control circuit 12, and the flow of the fuel 3 injected from the equipment 2 is varied periodically around the mean value, the fuel/air ratio which is the value of fuel flow divided by the air flow corespondingly changes periodically around the average fuel air ratio. If the theoretical fuel air ratio falls in the varying range of this fuel air ratio, the oxygen sensor 10 issues output of for example 0.2V in the time t in which the fuel is lean, and the other time of the period (T-t) will be fuel rich to output 1V, and the wave figure as shown in the drawing is obtained. Then, fuel air ratio can be obtained by calculating t/T by the arithmetic circuit 13.
