Filed: 1980-08-11
Abstract: PURPOSE:To reduce the number of arranged gratings formatching on an Si substrate, by providing a mask substrate with circuit patterns of X-ray absorptive material as well as with diffraction gratings for matching of X-ray transmitting material. CONSTITUTION:A mask substrate 31 is provided with circuit patterns 32 using Au and diffraction gratings 33 using Cr. The Si substrate 35 is prearranged periodically with V-grooves 36 playing a part of diffraction grating. Both gratings 33 and 36 are made to match by shifing by 1/2 periode for X-ray exposure. Thereby, the circuit pattern 32 forms a latent image within a resist 34 while the diffraction grating 33 does not form an image. Accordingly, when the resist 34 is fo negative type, the grooves 36 are protected by the resist at the subsequent etching, while when the resist is of positive type, the grooves are uniformly etched thus in both cases the original periode is not damaged to be fully useful for the subequent matching operation so that the diffraction gratings required for mathching are widely reduced with three spots X, Y and theta in the lease case.

Abstract: PURPOSE:To prevent abnormal increase of temperature, by a method wherein, when an evaporating combustion part is extraodinarily increased in temperature, combustion is stopped and energization to an evaporating heater is disconnected, and only a burner motor is operated to feed blast to the evaporating combustion part. CONSTITUTION:In case a contact 15a is brought into a welding state, energization to an evaporating heater 3 is continued, and when the temperature of an evaporating combustion part is increased to an excess rise detecting level determined by resistors 9, 10 and 11, the output of a comparator 13 is inverted to be brought to ''1''. This causes OR circuits 21 and 22 to be inverted a ''1'' output, and brings a combustion control circuit 26 into a stop state, forces driving parts 27 and 29 into an OFF-state, and brings a relays 30 and 31 into a non-exciting state, resulting in stop of combustion. Simultaneously, a transistor 25 is brought into an ON-state, the input of a driving part 16 is brought to ''0'', and a relay 15 is brought into a non-exciting state. Further, a signal is fed to a driving part 28, the relay 30 and a contact 30a are brought into an exciting state and a closing state, respectively, and a burner motor 4 is driven. This causes the air to be fed to the evaporating combustion part to cool it, and permits prevention of abnormal increase in temperature.

Title: Paper feeder for photocopier or the like
Inventor: ISHII YASUAKI
IPC: G03B27/00
Filed: 1979-08-31
Abstract: PURPOSE: To keep the thrusting force of a paper feed roller at a constant level independently of paper feed conditions and the progress in paper feed, by setting the weight and gravity center of a movable auxiliary bottom plate provided in a cassette and the stiffness constant of a spring for swinging a bottom plate push-up arm, so that the weight, gravity position and stiffness constant meet prescribed conditions.  
     CONSTITUTION: The torque T and stiffness constant (a) of a spring 11 are determined in accordance with formulae 1, 4 to optimize the thrusting force of a paper feed roller 3 for copying papers of one kind in size, thickness and weight. The weight P 3  of an auxiliary bottom plate 7, the position l 5  of a pin 7a, the gravity center l 3  of the plate 7, the gravity center l 2  of a copying paper stack 5, etc. are adjusted in combination so that the thrusting force P 1  of the paper feed roller 3 remains constant even if the weight of the copying paper stack 5 alters due to the change in the size and weight of each copy paper. The constant (b) of the formula 4 is determined by the unit weight and gravity center of the copying paper and the fulcrum of the auxiliary bottom plate 7. The thrusting force of the paper feed roller is thus kept constant despite the change in the properties of the copying paper and the fluctuation due to the progress in paper feed.
