Title: Measuring device of dynamic mtf of optical system of slit exposure copying machine
Inventor: SAKUMA NOBUO
IPC: G01M11/02
Filed: 1983-04-07
Abstract: PURPOSE:To enable the evaluation of an imaging performance in a dynamic state by a method wherein black-and-white fringes of a reflecting plate set at an angle of 45 deg. to the scanning direction are received through slits tilted at an angle of 45 deg. to the position of exposure and MTF is computed from reception outputs. CONSTITUTION:A reflection type chart 15 having a one-dimentional lattice with a pattern of black-and-white fringes arranged at equal intervals is set on a original stand at an angle of 45 deg. to the direction of scanning an original copy. On the other hand, a photosensitive body being removed when measurement is conducted, a light-receiving unit 16 in which slits l1-l3 are formed is disposed, with the direction of the slits tilted at an angle of 45 deg. to the direction of exposure, at the position of slit exposure, and is connected to an MTF operation unit 17. When an optical system is driven in these conditions, light-and-dark fringes of the chart 15 are transferred perpendicularly to the longitudinal direction of the slits, and the variations of the output signals thereof generate sine waves approximately. MTF is calculated by the operation unit 17 from the maximum, minimum and mean values of said signals. Thus, the imaging performance of the optical system in a dynamic state can be evaluated objectively.

Title: Logarithmic amplifier
Inventor: YAMADA TAKAHIKO
IPC: G06G7/24
Filed: 1980-05-09
Abstract: PURPOSE:To obtain an accurate logarithmic amplifier with a small number of parts, by utilizing the fact that the resistance between the drain and the source of an FET and the voltage between the gate and the source are in logarithmic relations with each other. CONSTITUTION:The drain of an FET17 is connected to the inversion input terminal of a DC amplifier 16, and the source is connected to the earth. The gate of this FET17 is connected to the noninversion input terminal of the amplifier 16. The input signal is applied to this noninversion input terminal, and the output signal is taken out from an output terminal 2 of the amplifier 16. Since the resistance R1 between the drain and the source of this FET17 is changed logarithmically for the voltage between the gate and the source, the resistance R1 is expressed by h.expVGS (h is a constant) when the voltage between the gate and the source is denoted as VGS. If the resistance value of a feedback resistance 18 is selected properly, the input voltage and the output voltage of this circuit are in logarithmic relations with each other.

Filed: 1978-05-23
Abstract: PURPOSE: To prevent buttons in a gondola except for a door opening button, an information button, etc. from functioning even if the former buttons are pressed when an illumination lamp is off, a motor generator is stopped and the door of the gondola is closed.  
     CONSTITUTION: When the gondola is stopped at a floor and the door is closed and the motor generator is stopped, a door open/close state signal 13 is at logic "L" and a motor generator state signal 14 is at logic "H" so that an AND gate 18 is opened. Since the output of an inverter gate 17 is at logic "L" and the output of an OR gate 16 is also logic "L", AND gate 19W28 are closed. Whichever button in the gondola is pressed at that time, one of button signals 1aW12a becomes "H" and passes through an OR gate 15 so that the output 18a of the AND gate 18 becomes "H". The output 18a is applied as a door opening instruction to a control unit to open the door.

Title: Method for pressure molding optical element
Inventor: YOKOTA MASAAKI
IPC: C03B11/08
Filed: 1986-03-19
Abstract: PURPOSE:To prevent air bubbles from forming on the optical face of a molded article in the drum part of a mold for molding an optical element by providing a heat insulator between a part introducing a material for molding and parts holding the upper and lower molds and retaining the material for molding at higher temp. than the upper and lower molds. CONSTITUTION:In a drum mold 3 of a molding die, a heat insulator 13 is arranged between a part 3a introducing a material 10 for molding and the parts 3b, 3c holding an upper mold 1 and a lower mold 2. Therefore the material 10 introduced into the drum mold 3 can be convergently heated by both a light source 7 for heating and a radiation heater contg. a reflective plate 8. In such a way, while making temp. difference between the material 10 for molding and the upper and lower molds 1, 2 in the drum mold 3, the material 10 is heated, softened and pressurized and molded by the upper and lower molds 1, 2. Thereby a fault such as air bubbles is not formed in the contact faces 19 between the upper and lower molds 1, 2 for the molded optical element 18 and the pressure molding is performed in a short time.

Title: Guide system for incoming call when one is absent
Inventor: TAJIMA RYOICHI
IPC: H04M1/57
Filed: 1989-03-14
Abstract: PURPOSE:To allow the subscribers not only of an analog network but of an ISDN network to receive respective types of guidance service by sending information on the basis of digital code when a calling side uses an ISDN network telephone device, and sending the information after converting it into a voice when the calling side uses an analog network telephone set. CONSTITUTION:When the telephone device is set in an absent mode by a mode set operating means 4, a CPU 2 always supervises an incoming call from an ISDN network, when the incoming call is generated, the CPU 2 reads the call setting message sent from the ISDN network through an S interface 1, and discriminates the type of the subscriber telephone network of the calling person by network discriminating information included in a call control message. When the calling person is the ISDN network subscriber, the CPU 2 outputs absence guidance, transmission ID notifying guidance, etc., on a sentence basis, and when the calling person is the analog network subscriber, it outputs the guidance on a voice basis. Thus regardless of the types of the subscriber telephone network of the calling person, the respective types of the guidance service for the incoming call when one is absent can be outputted.
