Title: Automatic sensitivity adjusting system for fish finder
Inventor: MATSUTANI HIROBUMI
IPC: G01S7/529
Filed: 1987-02-18
Abstract: PURPOSE:To adjust sensitivity automatically, by automatically controlling amplification factor in relation to a received signal level and two preset signal levels. CONSTITUTION:When the level of a reflected wave received by an ultrasonic wave transmitter/receiver 11 exceeds a set value of a comparator 17, amplification factor of an amplifier 14 is lowered through an amplification factor control circuit 22. When the level is below the set value of a comparator 18, the amplification factor is lowered. When the level of the reflected wave is between the two set values, the state of the current amplification factor is held. Thus, a control circuit 21 controls the amplification factor of the amplifier 14 to be between the two set values through the circuit 22. This enables automatic adjustment of sensitivity regardless of the level of the received signal when a set level is fixed at a specified value.

IPC: B29C33/40
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a simple mold which can be precisely formed by a low manhour at a low cost in a short delivery date, and its manufacture. SOLUTION: Optically shaped simple molds 1, 3 are composed of optically set resin which is set optically, and reinforcing particles which are mixed by dispersion in the optically set resin. In the optically shaped simple mold, the mold itself is basically composed of optically set resin, which is different from an absolute common sense in a conventional optically shaping process. Therefore, the simple mold can be directly (without any model) manufactured by an optically shaping process capable of being kept in contact with a so-called CAD and CAM system.

Title: System for synchronizing with multiplex spread spectrum receiver
Inventor: NAGAZUMI YASUO
IPC: H04J13/00
Filed: 1987-02-20
Abstract: PURPOSE:To supply an accurate clock to a pseudo noise generator by using two series of modulation codes included in a received signal so as to execute a partial demodulation and mutually exchanging chip synchronizing signals included in the signal obtained by demodulating the obtained part between two series of routes. CONSTITUTION:The binarization data of outputs from binary quantizing means 20 and 22 is given to coherent integration means 24 and 26. Namely, by using the means of the coherent integration so as to successively monitor the code change of the data, the bit timing of a modulated code which remains after demodulating the part is detected. The chip synchronizing signals obtained in such a manner are mutually exchanged as the clock signals clk-2 and clk-1 and respectively given to faulse signal generators 14 and 12. Therefore, internally composite clocks given to the pseudo noise generator are given from the timing information of the modulation code bit included in the input signal, so that accurate synchronism can be attained.

Title: Combined error control interleave system
Inventor: YASUDA YOSHIYUKI
IPC: H03M13/27
Filed: 1987-02-20
Abstract: PURPOSE:To prevent the deterioration of the combined effect of an external error control and to attain the effective transmission of signals even if burst error characteristic after Viterbi-decoding is changed by the state of a line by changing the timewise order of data series by the optimum interleave size according to the state of the line. CONSTITUTION:In a base station 1 and a mobile station 2 in which voice lines have been already set and the request of executing the communication of a non-telephone signal is issued, the mobile station 2 side selects the interleave size I from a table according to the fading period fD and the depth D of fading obtained by comparing the intensity of received electric field with the threshold level of (n) level and informs the interleave size information to the base station 1. After that, a transmission part changes the timewise order of the data coded with a second error control with considering the interleave size I as a unit and the data subjected to a convolution coding to be transmit. A reception part restores the data which is Viterbi-decoded based on the interleave size information and executes decoding of the second error control. Thus, the lowering of the efficiency of combined error control caused by the alteration of the state of the line can be prevented, so that the effective transmission of signals can be possible.
