Patent JP-S5681862-A (JP)
Title: Scanning exposure device
Inventor: TORIKAI SHIROU
IPC: G03G15/04
Filed: 1979-12-08
Abstract: PURPOSE: To alter the magnification ratio of projection in a simple constitution and without changing the velocity of the moving component, by providing the 1st, 2nd and 3rd reflecting components to the incident ray axis with a prescribed angle and then securing a fixed velocity for movement of these reflecting components.  
     CONSTITUTION: With illumination the light source 3, the picture at the end part (f) of the microfilm 2 set statically is reflected by the reflecting components M 1 , M 2  and M 3  which are set at the solid-line positions before scanning and by the luminous flux 8 to be projected in magnification at the position of the slit 6. The luminous flux 7 passing through the other end (e) of the film 2 is reflected by the reflecting component at the 1-dot chain line position where each of the reflecting components completes its movement at a fixed velocity in the direction of the arrow, and thus the flux 7 is projected in magnification at the position of the slit 6. In such way, the scanning exposure is possible without changing the moving velocity of the reflecting component or the photoreceptor but by altering the magnification ratio of projection using the lenses having different focal distances in place of the lens 1.

Title: Commodity rack for automatic vending machine
Inventor: ISHINO YUJI
IPC: G07F9/10
Filed: 1995-06-27
Abstract: PURPOSE: To eliminate such a trouble where a rack door of a commodity rack storing the heated commodities in a box of an automatic vending machine has a high temperature and an operator is astonished by the heat or anxious about a burn when he supplies the commodities. CONSTITUTION: A rack door 7 of a commodity rack which is contained in a box consisting of an adiabatic room is conventionally made of iron. However, the door 7 of this vending machine consists of an iron thin inner plate 71, a plastic outer plate 72 which has a knob 7a, and a strap-shaped adiabatic spacer 73 which is put between the side end parts of both plates 71 and 72. Thus the heat is hardly transmitted to the plate 72 although the plate 71 is heated by the heated commodities stored in the commodity rack. Furthermore, the heat caused by a high temperature in the box is not easily accumulated in the plate 72. Therefore, an operator is not astonished so much by the heat of the door 7 and never anxious about a burn even if he touches the door 7 to supply the commodities into the vending machine.

Title: Semiconductor device and manufacture thereof
Inventor: MUTO KOJI
IPC: H01L23/52
Filed: 1986-07-08
Abstract: PURPOSE:To obtain a polycrystalline semiconductor which can easily obtain a high resistance and be largely trimmed by providing a region which contains an insulating substance by coupling with the semiconductor at least at a part in the semiconductor having a predetermined value or more of an impurity density. CONSTITUTION:A high resistance layer 14 is presented between a first polycrystalline silicon layer 12 and a second polycrystalline silicon layer 5, and both are substantially electrically insulated therebetween. When the both are energized by a trimming power source 16 therebetween by 1X10<6> A/cm<2> or more of a current density in this state, the energy consumption of the current is increased in the layer 14, a boundary layer among crystal grains is melted over a wide range in the layer 14. When the energization is stopped, the melted region is solidified, but the segregation of an impurity occurs from a solid phase to a liquid phase. As a result, the concentrated part of an impurity density is formed at a part of the boundary layer. Accordingly, a passage of the current is formed in the boundary layer, and the resistance value of the layer 14 is substantially reduced to a value near the resistance value of the layer 12.

Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To obtain an IF signal, from which an image signal is removed, even when two communication bands to be used are of higher and lower frequencies than a local signal frequency. SOLUTION: Local signals having the mutual phase difference of 90 deg. at a local phase shifter 112 are respectively multiplied by two received RF signals distributed by a distributor 111 by multipliers 113 and 114 and the results are converted into IF signals. Then, the phase of one of two If signals provided by this conversion is advanced by 45 deg. by an IF phase shifter 115 and the phase of the other signal is delayed by 45 deg. by an IF phase shifter 116. While using these signals, an adder 117 and a subtracter 118 respectively perform adding synthesization and subtracting synthesization. Corresponding to whether the communication band to be used is higher or lower than the frequency of the local signal, any one of outputs from the adder 117 and subtrascter 118 is selectively outputted.

Filed: 1980-11-17
Abstract: PURPOSE:To enable an operator to make magnification varying operation easily by so constituting a titled machine that the association of a set original size and a selected copying paper size is distinctly identifiable through visual sense. CONSTITUTION:When an original is set on contact glass and is held by a pressure plate after turning of an electric power source to a copying machine body, a size pattern 12 corresponding to the original size is displayed on the display surface 1 of a display device. Namely, the original size is detected by an original size detecting means, and the predetermined code signal corresponding to that size is outputted from a control part, by which the size patter 12 on the display surface 1 is displayed. When the operator selects a desired copying paper size from the size display 2 and pushes a selection key 3 in succession to this, the corresponding code signal is outputted from the control part, and a size pattern 13 corresponding to the copying paper size is displayed. With such constitution, the operator is able to know the difference between the original and the copying paper size and therefore, he can vary magnifications easily.

Filed: 1984-07-31
Abstract: PURPOSE:To prevent an optical fiber from the reduction of strength and to detect disconnection precisely by inserting metal which is a conductive element for detecting disconnecting into a glass tube similar to the optical fiber, inserting the tubes into through holes formed into a preform and then drawing the preform. CONSTITUTION:Two through holes are symmetrically formed into a clad part 2 of the preform 6. After inserting a platinum wire into a quartz tube, its one end is sealed, its inside is reduced at its pressure from the other end under said state and the whole quartz tube is heated successively from the sealed part to unify the platinum wire with the quartz tube. The formed quartz wires are inserted into the through holes 7 of the preform 6 and the whole preform 6 is heated to unify the quartz tube with the preform 6 and to form the preform 6 including the conductive element. Consequently, an optical fiber characterized by sufficient mechanical strength and precise detection of disconnection can be easily produced.
