Title: Digital information reproducing method for rotary head type tape recorder
Inventor: KUSAKA HIROYUKI
IPC: G11B20/10
Filed: 1987-06-20
Abstract: PURPOSE:To fetch only a correct identification code by using parity check and majority decision of frequency of occurrence of signal patterns so as to detect the presence of a reproduction error of a reproduced identification code. CONSTITUTION:A sub information reproduction processing circuit 29 detects the presence of a reproduction error of an identification code, fetches the identification code without reproduction error and transfers it to a control circuit 30. In this case, the presence of reproduction error is detected from the identification code reproduced by one and same track for one trace based on the parity check for odd/even number blocks and the majority decision depending on the number of times of appearance of the signal patterns. Thus, even if a detection mistake takes place by the parity check, since the error detection of the presence of the reproduction error due to the detection mistake is prevented by the majority decision, the presence of reproduction error is detected remarkably accurately than the case with the parity check only.

Filed: 1981-09-29
Abstract: PURPOSE:To measure the actual condition of environmental noises accurately by interrupting the measurement of noises for the period when the sounds detected with a microphone put on the body are above the prescribed value. CONSTITUTION:After the noise signals collected with a microphone 11 are subjected to A characteristic amplification 12, the signals are subjected to square operation 13, and V/F conversion 14 to pulse trains.

On the other hand, the sounds produced by the operator per se is detected with a small-sized microphone 18 put on his body, and is applied via an amplifier 19 and a rectifier circuit 20 to a comparator 21. When the sound pressure thereof rises above the value that affects the measurement of noises, the output of the circuit 21 inverts to close the gate 17 thereby interrupting the inputting to the counter 15.

Therefore, the corner part 14A of the transfer sheet 14 is pulled up so that it is easily separated from the regular paper 12.  After that, the other part in a sticking state is peeled from the regular paper 12, to transfer the image to the regular paper 12 together with the sticking layer.

Title: Manufacture of polarization inverting crystal
Inventor: KOTOU MASAHIRO
IPC: G02F1/37
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To manufacture a polarization inverting element of high performance in high yield by selectively polarizing and inverting only a crystal part positioned right below the deepest part of a recessed groove or its near part. SOLUTION: An electrolyte EL1 which covers the surface of a polarization inverted area is not only present on the surface of surfaces HF between recessed grooves, but also covers the all internal walls of the recessed grooves by spreading to the bottoms of the respective partial recessed grooves H1, H2..., namely, the deepest parts and an electrolyte EL2 covers the entire reverse surface RF of ferroelectric crystal DC. Therefore, when a voltage V is applied between the electrolytes EL1 and EL2, a uniform voltage V can be charged between the top and reverse surfaces of the ferroelectric crystal DC.  The level of the voltage V is adjusted so that the electric field between the deepest parts of the partial recessed grooves H1, H2... and the reverse surface RF reaches right an anti-electric field value and the electric field between the surface HF and reverse surface RF is less than the anti-electric field value. Consequently, the part of the ferroelectric crystal DC right below the deepest part is polarized and inverted and no polarization inversion is caused right below each surface HF.

Filed: 1988-06-24
Abstract: PURPOSE:To prevent floating toner and ozone, etc., from being exhausted outside the machine by efficiently dust-removing/absorbing them by forming a cooling air passage in between an exterior panel and a frame plate surface, and leading the cooling air inside the machine collectively to a machine body bottom part, and exhausting it outside the machine through a dust removing filter, which contains ozone absorber. CONSTITUTION:Heat generating from an electric source/control device is led by the cooling air through a hole in the frame plate 35 and a space 36, formed in between the frame plate and the exterior panel 27, to an exhausting device 29. At the exit of the exhausting device 29 is provided the dust eliminating filter 33, further the ozone absorber is contained in the dust removing filter 33, the dust removal of the floating toner and paper dust, etc. and the absorption of the ozone is carried out here, and the air is exhausted outside the machine after being cleansed. Because this dust removing filter is attached to the machine exterior bottom part, sufficient ventillation area can be secured, the flow velocity of ventillation can be made small, lightening the load on a fan 30 of an exhausting device 29. Thus the dust removing efficiency ratio and the absorption ratio of the ozone are improved, preventing the contamination of the room by floating toner, paper dust, or ozone.
