Title: Radiation detector
Inventor: NARUSE YUJIRO
IPC: G01J5/20
Filed: 1986-09-04
Abstract: PURPOSE:To detect X-rays with high efficiency by alternately laminating metallic films and semiconductor films onto a substrate with irregularities in succession and connecting the metallic films to a signal leading-out terminal as a ground electrode and signal electrodes. CONSTITUTION:Mo metallic films 2, N-type a-Si films 3 and Ta metallic films 4 are deposited periodically onto a glass substrate 1 with irregularities. When X-rays 5 are projected from the cross direction, the metallic films having an irregular shape absorb X-rays extremely effectively. The energy of X-ray photons being absorbed is converted into the kinetic energy of photoelectrons by a photoelectric effect, and travels in the a-Si films 3, thus generating a large number of electron and hole pairs. On the other hand, the Mo metallic films function as a Schottky electrode and the Ta metallic films as an ohmic electrode, thus collecting signal charges generated to a signal electrode 6 by the same principle as a Schottky type photodiode.

Title: Device for detecting size of original
Inventor: ANDO HIRONORI
IPC: G03G15/04
Filed: 1988-08-19
Abstract: PURPOSE:To automatically and appropriately correct the variance of the characteristics of respective optical sensor by successively selecting the optical sensors according to a reference level calibration command, successively changing a reference level and storing the value in a reference level output means. CONSTITUTION:An original size sensor calibration switch 8, a print button 7 and a light emitting diode Di are turned on. epsiloni is inputted in a differential amplifier 2 from a D/A converter 4 as a reference voltage E from a microprocessor (MP) 5. Since epsiloni is smaller than an output Vi from a phototransistor Ti, the output Gi from the amplifier 2 is '0' and a comparison output Mi from a comparator is L. When Ei attains the brightness of an original for calibration by being successively increased, the Mi becomes H. Thus, the reference level Ei for the optical sensor Si can be set. After such an operation is performed with respect to i=1 to 6, the switch 8 is turned off and a switch 6 is turned on. The presence or absence of the original on the position of the optical sensor Si can be detected according as the Mi is H or L. Therefore, the size of the original is decided by deciding the presence or absence of the original with respect to i=1 to 6.

Title: Diversity receiver for portable radio equipment
Inventor: URABE SHIYUUJI
IPC: H04B7/08
Filed: 1983-11-07
Abstract: PURPOSE:To reduce the power consumption and to improve the speech quality by selecting an antenna changeover diversity or an after-detection synthetic diversity after detecting the phasing frequency. CONSTITUTION:The phasing frequency is measured by a phasing pitch detector and a controller 14. When the phasing frequency is low, a switch 11 is connected to a switch 10. Then the switch 10 functions as an antenna changeover switch for antenna switch diversity. The controller 14 delivers the commands shown by broken lines to mixers 2' and 4', an amplifier 6', a demodulator 7', a switch 13, etc. Then the parts turn off power supplies to reduce the current consumption. When the phasing frequency is high, the switch 10 is connected to an antenna 1 by a command of the controller 14. While the switch 11 connects an antenna 1' to the mixer 2'. Then the mixer 2' and others (4', 6', 7' and 13) are actuated as the after-detection changeover diversity receiver after the power supply is turned on. Thus the noise problem is solved.

Title: Portable radio equipment for reception of 2-branch diversity
Inventor: CHIBA KOUJI
IPC: H04B7/08
Filed: 1983-11-07
Abstract: PURPOSE:To attain reception of an incoming signal in a store mode of the titled radio equipment with a compact and light weight structure, by discriminating two antennas for an external antenna and a built-in antenna. CONSTITUTION:An external antenna 10 for reception of 2-branch diversity can be freely attached and detached. While another antenna 11 is set within a radio equipment. When the portable radio equipment is set under a calling state, both antennas 10 and 11 perform the diversity reception. Thus the transmission waves are radiated from one or both of the antennas 10 and 11. The antenna 10 is removed when the radio equipment is stored. In such a case, however, the reception is possible through the antenna 11.

Filed: 1989-08-14
Abstract: PURPOSE:To reduce leak current by forming a high concentrated impurity layer of second conductivity type in a second conductivity type layer between junction and a gettering layer. CONSTITUTION:In a semiconductor device having a junction of first and second conductivity type layer 2, 3 in a semiconductor substrate 1 and a gettering layer 4, a highly concentrated impurity layer 5 of second conductivity type is formed in the second conductivity type layer 3 between the junction and the getting layer 4. The concentration of impurity at this time is 10 times of higher than the concentration of the second conductivity type layer 3 forming the junction. In addition, such constitution is made that a first conductivity type layer 6 which can apply voltage to a part of the second conductivity type layer 3 between the junction and the getting layer 4 is formed. Further such constitution is made that the getting layer 4 is embedded in the first conductivity type layer 6 which can apply voltage formed in a part of the second conductivity type layer 3 forming the junction. A semiconductor layer 7 having band gap, different from that of the semiconductor substrate 1 where the junction is formed, is further formed between the junction and the gettering layer 4. Thus diffusion of a small number of carriers into the junction can be suppressed, resulting in the reduction of leak current at high temperature.
