Title: Analytic device for photographic survey
Inventor: OKUYAMA ATSUSHI
IPC: G01C11/06
Filed: 1990-03-30
Abstract: PURPOSE:To easily judge the position of a measurement point which is observed so far even with the naked eyes by providing an index projecting means or at least one observation optical systems of a binocular observation optical means. CONSTITUTION:A fixed observation optical system 10 has an index projection optical system 20. Luminous flux (m) from an index M is imaged as a projection index M' at the gauge point (a) of an aerial photograph 2. Then when the position of the measurement point (a) which is enlarged and observed so far is desired to be confirmed, the eye is moved away from an ocular lens 18 so as to observe the photograph 2 with the naked eye and then the brow of the observer OB leaves a brow pad 53. Consequently, a light shielding plate 54 moves as the brow pad 53 returns to its initial position with the elastic force of a spring 52 and luminous flux from a light emitting element 55 is released from being cut off. A photodetecting element 51 outputs its light receiving signal to turn on a thyristor 40 and then a light source 21 illuminates to project an image of the index M. Consequently, the observer OB can confirm the position of the measurement point (a) with the index M' and moves the photograph so as to align the index M' at a next-time observation point position, thereby aligning a measurement line N to the next-time measurement point position.

Title: Vertical magnetic recording head
Inventor: WATANABE YOSHIHIKO
IPC: G11B5/255
Filed: 1982-05-18
Abstract: PURPOSE:To prevent a signal from being recorded by an auxiliary magnetic head and a previously recorded signal from falling into disorder, and to improve wear resistance, by sticking an amorphous thin plate which is wider than the auxiliary magnetic pole at the top of the auxiliary magnetic pole on a medium contacting surface side. CONSTITUTION:A vertical magnetic recording head consists of a main magnetic pole 1' made of a several mum thickness thin magnetic film in a strip shape and the auxiliary magnetic pole 3' wound with a coil 2' for recording and reproduction which has a larger-area amorphous thin plate 8' stuck at the top of the medium contacting surface side. Consequently, the method of avoiding the convergence of magnetic flux by increasing the area of the auxiliary magnetic pole itself evades various losses such a an increase in inductance and an increase in necessary current, prevents a signal from being recorded by the auxiliary magnetic pole and a previously recorded signal from falling into disorder, and also improves the wear resistance.

Abstract: PROBLEM TO BE SOLVED: To easily prevent the deviation of a phase between horizontal and vertical synchronizing signals by measuring a phase difference between a signal synchronizing with a latent image forming means and a signal synchronizing with an image carrier or/and a transfer means and controlling the driving speed of a transfer means. SOLUTION: A horizontal synchronization detector 71 generates the horizontal synchronizing signal synchronizing with the latent image forming means (laser scanning optical system) forming a latent image on an image carrier (photoreceptor), and a vertical synchronization detector 40 generates the vertical synchronizing signal synchronizing with the image carrier or/and the transfer means (intermediate transfer medium and transfer medium roller) 102 forming a final image by successively superimposing plural visible images successively formed on the image carrier. A measuring means 100 measures the phase difference between the horizontal and the vertical synchronizing signals and a control means 101 controls the driving speed of the transfer means 102 based on the measured phase difference between the horizontal and the vertical synchronizing signals.  Thus, the deviation of the phase between the horizontal and the vertical synchronizing signals is prevented by correction performed in a comparatively short time with simple constitution.

Title: Binary-coding circuit control system
Inventor: KANEMITSU NORIO
IPC: G06K9/38
Filed: 1979-07-04
Abstract: PURPOSE: To reproduce a thinly darwn part by determining a slice level by detecting the maximum and minimum levels of thickness information.  
     CONSTITUTION: A pattern signal obtained by every scan on a picture is applied to shift register 10 and successively shifted, four by four bits, to shift registers 11W14. Every time it is shifted once, levels are extracted from registers 10W12 three times each and the mean value is calculated to obtain a center level. It is applied to shift register 16 and a level, extracted every time the input is shifted to shift registers 17W20 in sequence, is applied to 5×5 matrix part 35, which detects the maximum and minimum values of the black level to determine a slice level that corresponds to the value. This slice level signal is applied to binary-coding threshold-level determining circuit 38 and compared to a peak value output from n-scan peak detecting  circuit 37 to output larger one. On the basis of this signal, the input signal is  converted into a binary-coded slice pattern signal.

Title: Hot water temperature/quantity detecting unit
Inventor: OKADA JUICHI
IPC: F24H1/00
Filed: 1986-04-11
Abstract: PURPOSE:To make it possible to judge the existence or non-existence of water or hot water and to detect the temperature thereof by constituting the unit of an indirectly heated thermistor, a temperature detecting circuit, a heater heating power supply circuit, a voltage detecting circuit, a control circuit for carrying out a voltage control, a temperature setting circuit, and an output circuit for outputting data. CONSTITUTION:At the time of starting, in order to judge the existence or non-existence of hot water or water, a voltage of a power supply circuit 7 is increased, and a thermistor 1 is heated by a heater 5. The voltage and temperature upon this occasion are reported to a control circuit 4 by a voltage detecting circuit 8 and a temperature detection circuit 2. When an indirectly heated thermistor 6 is in hot water, the existence or non-existence of hot water in the initial period can be judged because the temperature of the thermistor 1 does not reach 100 deg.C even if a maximum output voltage is applied to the heater 5. If there is no hot water, the control circuit 4 repeats ON-OFF operation of the power supply circuit 7 by means of a voltage at which the thermistor 1 shows 100 deg.C, and an output circuit 3 emits a signal reporting that no water exists and the measured temperature of air at the OFF time of the power supply circuit 7. When the hot water reaches the location of the indirectly heated thermistor 6, the output signal is changed to indicate the existence of the hot water and its temperature.

Abstract: PURPOSE:To compensate the deterioration of the characteristics due to non-uniformity of ground inductance by making each ground inductance from each transistor cell to external grounding leads identical. CONSTITUTION:An input metallized pattern 2a and an output metallized pattern 2b are formed on an insulator 2k facing each other and a grounding metallized pattern 2c is formed between them. One end of each corresponding external drawing-out lead 2g is fitted to the end of the pattern 2c. At that time, the width of the central portion of the pattern 2c is formed larger than that of the portion near the lead 2g. Accordingly the ground inductance of the central portion is made smaller than those of the both end portions and the length of a bonding wire 2j from a transistor chip 2h is made shorter, so that the ground inductance of the bonding wire is also made smaller.
