Title: Original reader
Inventor: SUDA KENICHI
IPC: H04N1/04
Filed: 1985-10-25
Abstract: PURPOSE:To form a picture signal faithful to the shade of an original by providing a solid color image sensor, an invisible light removal filter means and a spectral distribution correction filter means decreasing an output difference corresponding to the each split color of a sensor. CONSTITUTION:Each photoelectric transfer element of the solid color image sensor 5 has a considerably high sensitivity to near infrared light and infrared light. Since a halogen lamp 2 radiates a large amount of near infrared rays and infrared rays, the photoelectric transfer element 521 senses near infrared light and infrared light among reflected rays from an original 0 lighted by the lamp 2. The general spectral sensitivity of the color image sensor 5, which a product between a spectral transmission factor and spectral sensitivity shows, varies with respect to each color light, and the spectral distribution of radiated light from the original lighting lamp is not uniform. A colored layer made of phthalocyanine is coated on a surface opposite to the deposition side of a near infrared light removal optical thin film 62 on a heat ray absorption glass 61, thereby forming a filter with a spectral transmission factor in an optical path. Then filters 6 and 7 are integrally formed and arranged. Thus a color picture signal faithful to the shade of an original can be formed.

Title: Turbine protector
Inventor: MATSUMOTO TAKUSHI
IPC: F01D21/16
Filed: 1983-12-19
Abstract: PURPOSE:To prevent a manual, unnecessary turbine trip by displaying the shaft displacement and vibration based on shaft vibration signals obtained from turbine shaft vibration detectors via an earthquake filter when an earthquake occurs. CONSTITUTION:An earthquake filter 8b is provided between a turbine monitor panel 7 and an indicator 9c. Even if an earthquake of a specified value or less occurs, outputs of seismometers 20a-20z do not reach a preset value alpha, thereby a relay 22 is not operated and a contact 23 is opened, thus only a low-frequency cut filter 8a is connected to the output side of the turbine monitor panel 7. When the outputs of the seismometers exceed the preset value alpha, the relay 22 is operated and the contact 23 is closed, thus signals from shaft vibration detectors 5a-5n are fed to the displacement indicator 9c and a vibration recorder 9d with low-frequency components (25Hz or less) cut off by the earthquake filter 8b, and an operator can monitor by observing the displacement excluding the effect of the earthquake.

Title: Temperature control method of thermostatic chamber
Inventor: KAWAI MOICHI
IPC: G05D23/19
Filed: 1984-11-14
Abstract: PURPOSE:To set quickly the temperature of air to a steady level within a thermostatic chamber by calculating an energization factor of each cycle in consideration with the heat leakage out of the chamber and giving the control of energization to a heater according to said energization factor. CONSTITUTION:A heater 11 is energized in a rising temperature band T1, and the energizing and non-energizing cycles are set to the heater 11 at an excessive temperature band T2 or higher. An energization factor A is calculated as A=alpha(PT/PM)X100(%) when the air temperature within a thermostatic chamber 1 reaches a set level T3. In this case, a constant based on the total leakage amount of heat out of the chamber 1 is shown by alpha; the quantity of heat radiated to the outside of the chamber 1 from the wall surface of said chamber is shown by PT; and the capacity of the heater 11 is shown by PM respectively. While the cycle energization factor B is calculated as B=beta(TS-T)+A(%) when the air temperature reaches the band T2 within the chamber 1. Thus the energization is controlled. Here beta, TS and T show a constant which decides the slope of the air temperature within the chamber 1, a set temperature level and the air temperature within the chamber 1 respectively. Then B=0 is satisfied with B<=0.

Title: Electrostatic capacity type reproducer
Inventor: ADACHI TOMOHIRO
IPC: G11B9/06
Filed: 1983-12-20
Abstract: PURPOSE:To avoid the deterioration in S/N of a detection signal by performing a control so as to increase the signal level of an oscillator which oscillates a resonance circuit. CONSTITUTION:A DC bias control circuit 7 makes use of a fact that the output signal C of an AFT control circuit 4 has a level proportional to a shift ratio from a resonance frequency fo and then divides a part of the signal C to use it as an input signal. Then the circuit 7 applies the DC bias to an oscillator 6 in response to the level ratio of the signal C. In other words, the level of the signal of the output B of the oscillator 6 is increased as the shift ratio of the resonance frequency of the circuit 7 increases to the frequency fo. In such a way, the signal output of the oscillator 6 is controlled even after the resonance frequency is changed to fo from foa by an AFT circuit 3. Thus the reduction of the resonance level can be avoided. This reproducer prevents the deterioration of S/N for a detection signal.
