Title: Magnetic recording and reproducing device
Inventor: IZAWA MASATO
IPC: H04N9/83
Filed: 1989-05-31
Abstract: PURPOSE:To reduce beat disturbance and to obtain an excellent video signal by controlling a characteristic of a trap circuit eliminating a voice signal component leaked in a chrominance carrier signal reproduced by a detection signal of an audio signal detection means. CONSTITUTION:A detector 16 detects the presence of an audio signal subject to frequency modulation sent from a band pass filter 15 and the characteristic of an audio carrier trap circuit 8 is switched with an output from the detector 16. When the audio signal is detected, the characteristic of the audio signal carrier trap is utilized and when the audio signal subject to frequency modulation is not detected, the audio signal carrier trap is eliminated. Thus, beat disturbance is less and when the audio signal subject to frequency modulation is not recorded, an audio signal carrier trap circuit 8 of the color signal reproduction processing system is eliminated to obtain an excellent reproduction picture without losing the color signal band.

Title: Manufacture of semiconductor laser
Inventor: HASHIMOTO AKIHIRO
IPC: H01S5/12
Filed: 1988-06-08
Abstract: PURPOSE:To stably form a grating by a method wherein a multiple-quantum-well structure of a light guide layer is made partially disordered by an ion implantation operation and an annealing operation using a a focused ion beam. CONSTITUTION:For example, Si is implanted into a multiple-quantum-well light guide layer 3 in a prescribed width at equal intervals by using a focused ion beam method. After that, an annealing treatment is executed, e.g., at 800 deg.C for 30 minutes under atmospheric pressure. Then, a multiple-quantum-well structure is destroyed; a region into which Si has been implanted in the guide layer 3 becomes a disordered region 5. A refractive index of the region 5 is different from that of an obliquely disordered region; accordingly, a distribution of the refractive index in the longitudinal direction, i.e. a grating, is formed on the guide layer 3. By this setup, the grating can be formed stably.

Title: System for measuring call loss
Inventor: NAKAYAMADA MASAYOSHI
IPC: H04M3/32
Filed: 1983-08-01
Abstract: PURPOSE:To attain the measurement of two-way call loss at a channel at the same time by providing a function increasing gradually a test tone transmission level to a master station device and providing a function allowing a slave device to be sensed at a certain level or over of a test tone and returning the test tone at a prescribed level to a master station side immediately after the sensing. CONSTITUTION:The maintenance personnel of a master station increases gradually the output of a test tone from a low level to a high level. When the output reaches a certain level, a level meter LM in a slave device is sensed. Then a test tone oscillator OSC in the slave station device is activated immediately and the test tone of a prescribed level is returned to the master station device. The transmission level value of the master station when the level meter LM of the slave station is sensed is recognized by allowing the maintenace personnel to listen to the test tone at a telephone set circuit TEL. Thus, the call loss in the direction from the master station to the slave station is recongnized. The test tone transmitted from the slave station is drawn to the master station level meter LM by allowing the maintenance personnel to operate a K2 key so as to measure the level. Thus, the call loss from the slave station to the master station is recognized.
