Title: Self-oscillation circuit
Inventor: TERAI HARUO
IPC: G01K7/24
Filed: 1986-07-04
Abstract: PURPOSE:To detect the temperature change a frequency change in an output with high accuracy quickly by changing a current flowing to a thermo-sensing resistive element depending on an output of a comparator so as to cause self- oscillation. CONSTITUTION:Since the temperature of a thermo-sensing resistive element (NTC thermister)1 is low at application of power, the voltage across the element 1 high and an output of the comparetor 5 goes to an L level. A transistor (TR) 7 is turned on, a resistor 8 is smaller than a resistor 2 and a large current flows to the NTC thermister 1. Then the NTC thermister 1 is heated in itself, its resistance is decreased, the voltage across the theimister 1 is lowered gradually and reaches a reference voltage, the output of the comparator 5 goes to an H level to turn off a TR 7, then the voltage across the NTC thermister 1 is dropped rapidly. The temperature of the thermister 1 is decreased gradually, the resistance is larger, the voltage of the thermister 1 rises gradually, and when the voltage reaches the reference voltage, the output of the comparator 5 goes again to L level, then the TR 7 is turned on. The operation above is repeated to cause the self-oscillation.

Title: Cellular receiver
Inventor: OGINO TORU
IPC: H04B1/06
Filed: 1990-06-16
Abstract: PURPOSE:To prevent the degradation in a reception sensitivity characteristic by providing a high frequency changeover switch and selecting the high frequency changeover switch so as to bypass a high frequency amplifier when a reception input electric field strength is a prescribed level or above and no SAT signal is detected. CONSTITUTION:When the strength of a reception input electric field is weak, a high frequency changeover switch 16 allows a reception signal to pass through a high frequency amplifier 3. Thus, the reception at a high reception sensitivity is attained. Consequently, when the reception input electric field is strong and a disturbing wave is inputted, an H level is outputted from a reception electric field strength detection circuit 12 and a SAT signal detection circuit 14 outputs an L level. Consequently, a NAND circuit 17 outputs an L level, the switch 16 is switched to short-circuit the amplifier 3. Thus, when a disturbing wave from other device is present thereon, the high frequency amplifier 3 is short- circuited to decrease crosstalk in a 1st mixer 5, thereby improving the inter- modulation characteristic of the receiver.

SOLUTION: A film surface 64 is curved in the longitudinal direction of the exposure screen in order to correct the field curvature of the photographic lens 60. The photographic lens 60 is constituted of a 1st meniscus lens 61 having a convex face on an object side and a 2nd meniscus lens 62 having a convex face on an image side, and provided that a length from the film surface 64 to an exit pupil 63 on the optical axis 60a is expressed by Ep, the projecting amount toward the object side of the film surface 64 at the corner of the exposure screen with reference to the film surface 64 on the optical axis is expressed by δ, and when Db=(δ/Ep)×100 is established, the optical distortion DS(%) of light going from the exit pupil toward the corner of the exposure screen on a plane 65 including a paraxial focus is controlled so as to satisfy '-10<=Ds<=Db-0.5'.  Thus, the image where various kinds of aberration other than the distortion are suppressed is exposed on the film 64, and in the case of improving the image quality at the digital image processing, the image of high quality is obtained only by correcting only the distortion.

Title: Semiconductor photo-electric surface and its manufacture
Inventor: MATSUMOTO SHOHEI
IPC: H01L27/146
Filed: 1991-07-01
Abstract: PURPOSE:To form a semiconductor photo-electric surface with which a desired photo-electric sensitivity is secured in a normal degree-of-vacuum environment without using an ultra-high degree-of-vacuum environment around 10<-7>Torr. CONSTITUTION:A CsO or Cs active layer 5 is formed over the surface of a P-type GaAs layer 3 provided on a P-type Al0.5Ga0.5As layer 2, which is affixed to a glass window 1, and a semiconductor photo-electric surface is produced. Between these active layer 5 and GaAs layer 3, a single atomic S layer 4 is formed under a normal vacuum around 10<-7>Torr. This single atomic S layer 4 has a stong bond with the surface of the GaAs layer 3 to hold the interface crystalline condition extremely stably without admitting interferential existence of oxygen at the surface, and production of a natural oxide film is suppressed which otherwise hinders remarkably the photo-electric sensitivity generated at the over-surface of the P-type GaAs layer 3. An incident beam of light 101 passes through the Al0.5Gao.5As layer 2 to reach the GaAs layer 3 to generate an electron-hole couple. After passing the S layer 4 in the form of thin film, it further penetrates the active layer 5 owing to the tunnel effect to then be emitted as photo-electron.

Title: Atmospheric pressure ionization ion trap mass spectrometry method and device

IPC: H01J49/34
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To quickly obtain mass spectra containing molecular weight information and structure information and reduce the consumption of a valuable sample. SOLUTION: Charged fine liquid drops 40 discharged from the tip of a metal capillary 2 advance through the atmosphere 4 along an electric field, collide against atmospheric molecules to be divided into very fine particles, and finally ions are exhausted into the atmosphere. The produced ions are accelerated with an intermediate pressure part 9 of an ion introducing part, and introduced into a mass spectrometry part 24 through an ion focusing/transfer line part 20 of the ion introducing part. The ions are trapped and stored in three- dimensional quadrupole field of the mass spectrometry part 24. The stored ions fly out by the sweep of the quadrupole field, are detected with a detector 15, and produce mass spectra. During the storage of ions, accelerating voltage is switched in two steps. Therefore, collision/dissociation of ions to neutral molecules is conducted in the different collision/dissociation conditions, and the mass spectra have both molecular weight information and structure information.
