Title: Pcm voice multiplex method
Inventor: HIOKI TOSHIAKI
IPC: H04N19/00
Filed: 1986-02-20
Abstract: PURPOSE:To reduce a data error by converting a voice data into a 4-value level signal at 2-bit each, applying base band multiplex during the vertical blanking period and setting the 2-bit pattern to a pattern different from the adjacent bit pattern. CONSTITUTION:A PCM voice signal subject to base band multiplex is inputted to a shift register 5 during the vertical blanking period of a band compression video signal. The register 5 outputs the PCM voice signal at 2-bit each from output terminals Oa, Ob. A D/A converter 7 converts the 2-bit at input terminals ia, ib into a 4-value level signal analogically. An analog switch 8 outputs a band compression video signal of a clamp circuit at a period other than the vertical blanking period and outputs an output signal of the converter 7 during the vertical blanking period.

Abstract: PURPOSE:To obtain a uniform image which is not affected by a mechanical vibration and has no toner coagulation, by forming a developer carrier into an elastic hollow cylinder and dispersing the pressure, which is applied to a developer at a pressurizing time, by subjecting to deformation of this carrier. CONSTITUTION:A toner 7 is send to an electrostatic latent image 2 by the rotation of a hollow and cylindrical developer carrier 3 consisting of an elastic material and is pressurized and brought into contact with the latent image 2 to develop 10.

Further, a photosensitive layer on a holding material 1 is not destroyed mechanically, and setting of development conditions is facilitated. The width of contacting between the holding material 1 and the carrier 3 is 5-15mm. and is 2-5 times as wide as a conventional width to prevent the development variance due to the mechanical vibration, and the effect of a bias 11 is improved, thus obtaining a good image without fog.

IPC: G11B5/09
Filed: 1987-02-20
Abstract: PURPOSE:To record a digital signal with high density by recording a digital signal obtained by modulating the phase of a reference frequency in an audio cassette tape. CONSTITUTION:A frequency waveform (reference frequency) having no phase shift from a digital signal consisting of the prescribed number of bits in a front edge part A is outputted to an audio cassette tape recorder. When a digital signal in a data part B is phase-modulated so that the phase of its frequency waveform is shifted by 180 deg.(pi) and a 2nd bit '1' in the data part B is phase- modulated, the phase of the frequency waveform coincides with the '0' phase of the preceding phase because the preceding bit is '1'. When a 3rd bit '0' in the data part B is inputted, the phase of the frequency waveform is shifted by 180 deg.(pi) because the preceding bit is '1'. Then, the phase of a digital signal in a check part C is modulated. Thus, the recording density can be improved approximately 5-10 times as compared to recording density in an ordinary recording system.

Title: Cavity depth measuring device
Inventor: AANORUDASU YOSEFU BORUSUTO
IPC: A61C19/04
Filed: 1982-03-11
Abstract: A measuring instrument for the depth of the periodontal cavity comprises a probe needle (2), a needle holder (3) and a handle (1). The needle (2) with the needle holder (3) is restrictedly pivotable from a start position determined by an abutment against the action of a bias spring, the deformation of which caused by the needle movement causes no substantial change of the spring force. To this end the needle holder (3) and the handle (1) each are attached to parts of a hinge (4). The hinge parts (5, 6) are biased to the closed position of the hinge (4) by a spring (8, 12, 13, 14) with a spring characteristic which is substantially flat at least within the restricted pivoting range of the hinge. 
<??>In this manner the hinge of the measuring instrument can be made compact and especially flat whereby the user of the instrument has a good view on the probe position under all circumstances. The measuring instrument is constructively simple, can be manufactured relatively cheap and can be more easily sterilized.
