Title: Sound recording device
Inventor: YOSHIZAWA KEIICHI
IPC: G11C27/00
Filed: 1986-07-25
Abstract: PURPOSE:To obtain a sound recording device which is excellent in portability, operational function and preservation and also efficiently records without omission by cyclically selecting the address of a storage circuit and sequentially rewriting to inputted voice information. CONSTITUTION:The voice collected with a microphone 4 is converted into digital data in an A/D conversion circuit 5 and encoded in and encoding circuit 6 so as to be sequentially written in the storage circuit 7. Since it is previously decided that the storage capacity of the storage circuit 7 is about 4sec, when a write is executed to the last address the write is executed from the first address again, namely, the write is cyclically executed. Since a user has only to stop recording sound about 4sec after the voice which he wants to record is given, he can record sound without omission and without needless part of sound recording. And also since the storage circuit 7 is detachable, only this storage circuit can be sent as a taped letter. And the device is extremely small, so that it is excellent in portability and preservation.

Abstract: PURPOSE:To enable an obstacle for an aircraft which is located on or near an approach surface at an airport to be found previously by radiating a first beam at an elevation which matches an approach angle of the aircraft and at the same time radiating a second beam onto a ground surface at an elevation of 0. CONSTITUTION:A circulator 12 outputs a transmission energy from a transmitter 11 to an antenna 10. The antenna 10 is wide in vertical direction, radiates an antenna beam with a small angle width in a direction of azimuth angle, receives an echo from a target, and then outputs a second reception signal. An antenna 14 is narrow in vertical direction, radiates an antenna beam with a large angle width in the direction of azimuth angle, receives the echo from the target object, and then outputs a first reception signal. A receiver 15 receives the second reception signal and outputs an output signal B which indicates that the target exists when a signal intensity where an aircraft signal is eliminated exceeds a specified level. A receiver 16 outputs an output signal A which indicates that the target exists when a reception signal intensity from the antenna 14 exceeds a specified level. An obstacle-discriminating portion 20 judges an obstacle according to the signals A and B, thus enabling a danger to be indicated.

Title: Plasma spot welding method
Inventor: SASANO RIYOUICHIROU
IPC: B23K10/02
Filed: 1983-09-22
Abstract: PURPOSE:To prevent generation of the cavity in a weld zone and formation of oxide and nitride in the stage of welding while spraying gaseous plasma at a high temp. by adjusting the flow rate of the gaseous plasma prior to and after completion of a decrease in welding current. CONSTITUTION:The flow rate of gaseous plasma 109 is increased after the increase of welding current is started. The flow rate of the gaseous plasma 109 is decreased before the welding current is decreased. The decrease of the gaseous plasma 109 is continued even after the completion of the decrease in the welding current. The flow rate of the gaseous plasma 109 is thus adjusted in association with the welding current. Spot welding is thus executed without generation of a cavity 113 and without oxide and nitride.

Filed: 1989-07-10
Abstract: PURPOSE:To allow an operator to know parity data without using a measuring instrument by reading out the parity data stored in a reading parity latching means from a processor. CONSTITUTION:A storage part 3 reads out parity data added to data simultaneously with the sending of the data to the processor 1 and sends the parity data to the reading parity latching means 4.

At the time of receiving a reading request of the parity data stored in the means 4 through a parity reading command line 9, a parity reading means 5 sends the parity data to the processor 1. Since the parity data are read out from the storage part 3 by this operation, the parity state can be checked without using a logic tracer or the like.
