Abstract: PROBLEM TO BE SOLVED: To make portable radio device small in size and excellent in handeability and workability by converting space wave frequency received by means of mobile station on board device into an inductive radio frequency, transmitting it to a ground base station, directly receiving the inductive radio frequency of a transmitting signal from the ground base station without conversion and demodulating it. SOLUTION: A voice signal from a drive commanding place 5 is modulated in the ground base station to be the inductive radio frequency f1 and radio wave transmitted to an inductive line 3 is received by the receiving antenna 15 of mobile station on board device. The received radio wave is added to an inductive radio receiver 19 from a distributor 17, demodulated and amplified. In the meantime, the voice signal from a microphone 21 is added to an inductive radio transmitter 23, demodulated and amplified to be the inductive radio frequency f2 and electromagnetically induced to the inductive line 3 from a transmitting antenna 24 as the inductive radio frequency f2. The inductive radio frequency f2 is demodulated and amplified in the ground base station 4 and transmitted to the drive commanding place 5 so that mutual communication is executed.  Therefore, handling is simplified and work efficiency is drastically improved.

Title: Pulse type ultrasonic object detector
Inventor: YAMANE TOSHIKI
IPC: G01S7/527
Filed: 1985-12-13
Abstract: PURPOSE:To prevent erroneous operation due to noise, by providing a signal processing circuit comparing the receiving signals of a noise receiving sensor and a transmitting- receiving sensor to remove a noise component and outputting the detection signal of a reflected wave. CONSTITUTION:A transmitting-receiving sensor 3 is driven by a transmitting signal circuit 5 to emit an ultrasonic pulse (w) and receives the reflected wave rw of the pulse (w) reflected by matter 2 and returned therefrom to convert the same in to a receiving signal which is, in turn, sent to a receiving circuit 6. The transmitting signal circuit 5 sends a transmitting signal (s) to the circuit 6. The circuit 6 receives the signal (s) from the circuit 5 to take out only the part of the signal (s) contained in receiving gate preset after a definite time from transmission to send the same to a subtractor circuit A. Next, a noise receiving circuit 7 receives noise (n) containing a noise component, which is received by the sensor 3 with respect to the noise pulse N1 received by the circuit 3 and converted by the circuit 6, through a noise receiving sensor 4 and converts said noise (n) in to a noise pulse N2. The circuit 8A detects the difference between the output of the circuit 5 and that of the circuit 7 to remove the pulse N1 generated in the circuit 6 and erroneous operation due to the pulse N1 is prevented.

IPC: H04L1/18
Filed: 1991-10-28
Abstract: PURPOSE:To provide a communication system which can perform the communication of data with high efficiency for the communication of data carried out between the information processors. CONSTITUTION:The information processors 3a and 4a are communicatably connected to the radio equipments 1a and 2a which contain the transmitting data buffers 7c and 7d and the receiving data buffers 8c and 8d respectively. The communication of data is carried out between both processors 3a and 4a by radio through the buffers 7c, 7d, 8c, 8d. That is, the transmission data are previously divided into the blocks of each prescribed size and transmitted. When the divided data are received by the equipment 2a of the receiver side, the information is transmitted to decide for each block whether the received data include an error or not. Thus the equipment 1a of the transmitter side receives the information and transmits only the relevant block 3/N that has a reception error.

Filed: 1988-11-08
Abstract: PURPOSE:To increase the saturation magnetization of a magnetic layer so that a double layer type magnetic recording medium whose output is improved can be obtained by applying a magnetic paint for a second magnetic layer before a paint film by a magnetic paint for a first magnetic layer becomes dry.

IPC: A61B6/00
Filed: 1989-10-31
Abstract: PURPOSE:To prevent the part of a photographic image void by a name imprinting part by turning a press contact plate in the plane of the plate in a process where the press contact plate is moved from a standby position to a photographing position, and displacing the name imprinting part of an X-ray film held with the press contact plate to a different position. CONSTITUTION:The press contact plate 1 is rotated in a plane including the plane of the plate centering a rotary shaft 35 while it is moved from the standby position A to a name imprinting position B. Thereby, the direction and the position of the press contact plate 1 are changed by 180 deg.. An image can be formed by receiving the X-ray emitted from an X-ray tube and transmitting a subject. In such a case, since the name imprinting part Fa of the X-ray film is located at an upper part shown in the Figure where no influence is applied to the image of the photographing part of the subject formed on the film F, a satisfactory image can be obtained without being obstructed by the name imprinting part Fa of the X-ray film F. Thereby, it is possible to prevent the image formed on the X-ray film F voided by the name imprinting part Fa of the X-ray film.

Title: Manufacture of semiconductor device
Inventor: KUDO SATOSHI
IPC: H01L21/225
Filed: 1986-11-28
Abstract: PURPOSE:To pile impurities up in a substrate, thereby forming a shallow pn junction by depositing a metallic film of such as W and the like on the surface of the Si substrate and then, by implanting the impurity ions in the metallic film and performing a sinter treatment. CONSTITUTION:Diffusion of B (Boron)-ions through implantation is carried out after photoetching of a base region and a base p diffusion layer 3 is formed at the surface of a silicon substrate 1. Metals such as W or Mo are spattered on the full face and a metallic film 4 of around 2-3000Angstrom  thickness is formed. And then, an impurity ion implantation such as that of As (arsemic) is carried out in the metal (W) film. In such a case, an implantation energy is controlled so that As will not thrust a W film. The W film is treated by a sinter process at a temperature of about 600 deg.C and As in the above W is diffused (piled up) in the silicon substrate. Then a diffusion layer 5 formed by piling up turns into an emitter n<+> region with an exceedingly shallow junction that is around 500Angstrom  deep.
