Title: Reader of cards in plural columns
Inventor: KOMATA KIICHI
IPC: G06K7/00
Filed: 1984-02-29
Abstract: PURPOSE:To obtain a system free from erroneous reading in card having 80 columns reading by reading out the 1st line of a card in plural columns by means of converting a change in the difference of an output waveform of surfaces in plural columns into a sample pulse. CONSTITUTION:The titled reader is constituted in such a way that the difference of an output waveform of a change in a surface of a card (non-printed part, printed part, punched part, etc.) is made into a sample pulse as it is. Since an output of the 1st row functions as a sample pulse at the same time reading indication is given to sensors for the 2nd, 3rd rows... when a counted value of the 1st row is ''1'', and these sensors operate. The time inherent to the device is required for such processing. During the processing cards are fed at the specific speed. A sensor 21 of the 1st row is shifted by a distance DELTAx away from the 2nd and the subsequent sensors 22, 23.... Since an output of the 1st row functions also as a sample pulse, reading indication is given to other sensors at the actual point when a reading part reaches sensors; therefore high accuracy of card feeding is not required.

Title: Drying furnace
Inventor: KADOWAKI HIROYUKI
IPC: F26B15/12
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To dry a coating formed on a substrate uniformly by shaking a substrate held at a drying position in a tact transfer furnace for transferring the substrate between drying positions by means of a shaking mechanism. SOLUTION: A coating is dried by heating a substrate by means of a heater 21. Air is sucked through a duct into a furnace and the air containing a volatile solvent is discharged through a duct 22 to the outside. When the substrate is carried in to the lower stage of a drying furnace 20, the substrate carried onto the roller 12 of a frame 11 is carried, as it is, onto a carry roller 23 at the lower stage of the drying furnace 20. When the substrate is carried onto the upper stage of the furnace 20, the frame 11 is moved to an ascending position if the substrate is present on the roller 12 and the substrate is carried onto a carry roller 23 at the upper stage of the furnace 20.  Fluctuation in the plane of the substrate caused by presence/absence of a rear surface holding mechanism, i.e., the carry roller, can be suppressed by shaking the substrate at the drying position thus realizing uniform drying of coating.

Title: Shape measuring method
Inventor: UBUSAWA YOSHIHIRO
IPC: G01B17/06
Filed: 1992-01-28
Abstract: PURPOSE:To accurately measure the three-dimensional shape of a human body wearing cloths by projecting acoustic waves upon the human body and detecting reflected acoustic waves with an acoustic-wave receiver, and then, subtracting components other than the reflected waves from the human body from detected interference signals by performing arithmetic operations. CONSTITUTION:Acoustic waves are continuously projected upon the human body wearing clothes from an acoustic-wave oscillator 1. An acoustic-wave receiver 3 detects acoustic waves produced by the superimposition of individual amplitude and phase components of a plurality of reflected acoustic waves from the human body and clothes by interference. Then only the reflected waves from the human body are found by subtracting components other than the reflecting acoustic waves from a plurality of components of detected interference acoustic signals by performing vector arithmetic operations. The distances from the oscillator 1 and receiver 2 to the surface of the human body are found from the reflected signals from the human body. When the same-distance locus 6 is drawn based on the 'oscillator 1-object 3-receiver 2' distance, the locus becomes an elliptic sphere circumscribing the object 3. Therefore, when a plurality of elliptic spheres 6 circumscribing the object 3 are drawn based on the measured results, the shape of the human body can be found.

Title: Rotary head type magnetic recording and reproducing device
Inventor: OKABE YOSHIMASA
IPC: H04N5/92
Filed: 1990-02-20
Abstract: PURPOSE:To eliminate the need for the correction of a horizontal synchronizing signal even at special reproduction by varying a clock frequency with write and read of a reproduced video signal to/from a memory so as to cancel expansion and compression of the video signal. CONSTITUTION:A control signal (f) is recorded on each of two tracks on a tape, detected by a control head 5 and a time interval of a control signal is measured by a counter 6 operated at a stale clock obtained by an oscillation circuit 8. Since the time interval is inversely proportional to the tape speed, a microcomputer 7 calculates the period of the horizontal synchronizing signal of the video signal reproduced based thereon. Thus, the clock frequency is varied with write and read of the reproduced video signal into the memory 11 to apply extraction and contraction to cancel the expansion contraction of the video signal. Thus, the correction of the horizontal synchronizing signal is not required even at the special reproduction.

Title: Focus detector
Inventor: ABE TAKAYUKI
IPC: G02B7/28
Filed: 1989-02-21
Abstract: PURPOSE:To always stably detect the in-focus state with high precision without having influence upon birefringence of an object to be irradiated by providing a prescribed reflecting member in the reflective optical path of the object to be irradiated and providing a 90 deg. optical rotating element between a photodetector and this member. CONSTITUTION:The radiated light from a laser light source 21 is converged on the surface of a recording layer 26B through an optical system and a transparent protective layer 26A. The reflected light from this surface is made incident on a half prism 24 and is reflected by a prism surface 31. This reflected light passes a halfwave plate 33 and is made incident on a detecting prism 34 and is reflected by a reflecting face 35 and is received by a photodetector 36 having two-divided light reception areas 36A and 36B. In such a case, the reflected light from the recording layer 26B is elliptically polarized by an influence of the protective layer 26A, and p-polarized light and s-polarized light are mixed in the incident light to the prism 30, but almost all s- polarized light is reflected by the surface 31. This s-polarized light has the plane of polarization rotated at 90 deg. by the plate 33 and is made incident on the face 35 as p-polarized light. Consequently, the detection sensitivity is not degraded though s-polarized light is included in the incident luminous flux to the prism 30, and the in-focus state is stably detected with a high precision.
