Title: Distortion inspecting device
Inventor: SHINOHARA MASAHITO
IPC: G01B11/24
Filed: 1988-06-27
Abstract: PURPOSE:To enable the determining of a distortion in a sample quantitatively by a method wherein a sample is irradiated with light having a well-adjusted wave front to project a distortion in the sample on a screen and the brightness of an image thereof is measured with a photo detector. CONSTITUTION:Light from a light source 2 is condensed with a condenser lens 3, passed through a pinhole 4 to adjust a wave front precisely and made to irradiate a sample 1 rotatable with a pulse motor 7 through a reflector 5. Reflected light from the sample 1 is projected onto a transmission/scattering type screen 8 and an image thereof is measured with a photo detector 9 to supply a detection signal to an arithmetic device 10. Then, the brightness of the image on the screen is calculated. Then, when a warping occurs with a distortion of the sample 1 down outward, the image on the screen grows to reduce a light detection signal with the image darkening. In the case of an upward warping, all are opposite to this. This enables the determining of a value of the warping quantitatively from an output value of the light detection signal.

Title: Output circuit
Inventor: WATARAI SEIICHI
IPC: H03K19/003
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To suppress variations in the output signal amplitude and to reduce a decrease in transmission rate, an increase in power consumption, and an increase of noise generated at the time of signal transmission by providing a voltage control means which controls the supply voltage of a transistor. SOLUTION: A voltage control circuit 3 is provided which is interposed between a power source VDD and the source of a transistor M11 for controlling the supply voltage to the transistor M11. The transistor M11 serves to control voltage in the voltage control circuit 3, and its output potential is the value obtained by subtracting the gate-source voltage of the transistor M11 from the source voltage VDD. The output potential of this voltage control circuit 3 has the quantity of variation in the source voltage VDD as it is in such a case, Therefore, even when the conduction resistance of the transistor M11 varies greatly, the absolute value of the variation can be made small to match a drop in the gate-source potential outputted by the transistor M11 of the voltage control circuit 3, thereby suppressing variation in an output H level.

When switches 8 or 9 is disconnected, an output of the NAND circuit 39 goes to ''0'' and an output of the NOT circuit 41 goes to ''1'', then an output of an OR circuit 46 goes to ''1'' and the output of the NOT circuit 44 goes to ''0''. Since the output of an NAND circuit 40 is at ''1'', an output of an NOT circuit 45 goes to ''0'', an output (b) of the OR circuit 47 goes to ''0'' so as to attain the disconnection of switches 6 or 7.

Title: Radiation thermometer
Inventor: INUI HIROFUMI
IPC: G01J5/00
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To save power by supplying a motor for driving a translucent plate with a battery voltage divided through a resistor thereby reducing power consumption. SOLUTION: Infrared rays corresponding to body temperature radiated from the eardrum of a person, for example, are detected by an infrared sensor 11 through a probe 1. Based on a command from a temperature converting means 16, a motor control means 14 rotates a motor 13 normally or reversely to open or close the light incident window of the infrared sensor 11 with a translucent plate 12 interlocked with the motor 13. When the light incident window is opened, infrared rays corresponding to body temperature detected by the infrared sensor 11 are inputted to the temperature converting means 16 and when the light incident window is closed, temperature of the infrared sensor 11 itself detected by a sensor temperature detecting means 15 is inputted to the temperature converting means 16.  The temperature converting means 16 operates the body temperature based on both detection signals and displays the body temperature on a display means 17. Since the translucent plate 12 is operated through rotation of the motor 13 supplied with the voltage of a battery 10 divided through a resistor 18, applying voltage can be decreased and power consumption can be saved.

Title: Mechanism for conveying photographic paper
Inventor: SASAKI MASAKI
IPC: G03B27/62
Filed: 1983-09-02
Abstract: PURPOSE:To prevent malfunction and to make mechanism compact by transmitting the self-maintaining force when a driving source for conveying the photographic paper stops to a photographic paper winder thereby regulating excessive winding. CONSTITUTION:A winding shaft of a photographic paper winder 15 is driven via gears 30, 31 to wind successively photographic paper P under conveyance. One- way clutch 22 does not drive a shaft 29 during revolution in an arrow direction and drives backward said shaft during reverse revolution. If the shaft 29 is going to revolve in an arrow direction when a motor 11 and the clutch 22 stop, the clutch 22 transmits the rotating direction in the counter arrow direction and therefore the rotational force is transmitted to the motor 11 and is braked by the self-maintaining force of the motor 11. The winding shaft of the winder 15 is driven via a friction mechanism so as to rotate according to the winding amt. of the paper P and since the overrun that the winding shaft is going to make when the feed for the photographic paper stops is braked by the self-maintaining force of the driving motor itself which is interlocked via the one-way clutch mechanism to said shaft, there is no need for providing a damper between a feed roller 12 and the winder.

Abstract: PURPOSE:To carry out a call and any other communication than the call at the same time by dividing the frequency band of a narrow-band communication circuit and then by using an intermediate band for any other purpose than the call. CONSTITUTION:Intermediate part of a sound signal component for a call is removed by a band-stopping filter, its lower frequency component 3a and higher frequency component 3b are transmitted for calling, and a signal for data communication or picture communication is transmitted by using intermediate frequency band 4 with the sound signal component removed by the filter. Here, the transmission of the higher frequency component is to reduce the lowering of articulation as much as possible. Since calling occupied-frequency width 1 of the subscriber's telephone circuit is 3100Hz between 300Hz and 3400Hz, component 3a and component 3b are used for calling being between 300Hz and 1400Hz, and 2200 and 3400Hz respectively, and the remaining band of 1400-2200Hz is used for data communication. Consequently, it is made possible to attain multiplex communication of telephone service and data, and the circuit can be utilized efficiently.
