Title: Production of ultrathin metal film
Inventor: MORI MASATO
IPC: G02B5/30
Filed: 1989-01-11
Abstract: PURPOSE:To obtain a thin metal film having superior smoothness and especially suitable for use as an optical deflection circuit element even in the case of a sufficiently small thickness by mixing a sputtering gas with a nonoxidizing gas when a thin metal film is produced by sputtering. CONSTITUTION:A sputtering gas such as Ar is mixed with a nonoxidizing gas such as H2 and sputtering is carried out with the gaseous mixture to produce an ultrathin metal film. By this method, the molecules of the gaseous H2 are decomposed in plasma to generate atomic H and this atomic H is adsorbed on the growing surface of a thin metal film. The surface is temporarily coated with the atomic H, the adsorption of oxygen on the surface is inhibited and the oxidation of the metal film is prevented. By keeping a substrate at a relatively low temp. of about 200-300 deg.C, the surface of the metal film is etched by the atomic H and the smoothing of the surface is accelerated.

Title: Copying machine
Inventor: ITOU MASAZUMI
IPC: G03G15/00
Filed: 1984-01-11
Abstract: PURPOSE:To control conveyance of copying paper by conveying the copying paper in such a way that the succeeding copying paper comes to a copying position after the copying paper is fixed with an image and is discharged to the outside in the stage of continuous copying and stopping the feeding of the succeeding copying paper when the copying paper after copying is jammed. CONSTITUTION:A CPU300 is used to control a copying operation and is connected to respective keys on an operation panel, for example, a key 301 for setting the number of copies, a print key PS, a clear stop key CS, a timing switch 52 for outputting an operation signal of a timing roller 24, a sensor 130 for detecting copying paper, a sensor 131 for paper discharge, etc. The processing by the CPU and the operation of the copying machine are synchronized during running of a motor. Respective steps are executed at the specified period regulated by an internal timer while the motor is in stoppage. If the copying paper after transfer is jammed during continuous copying, the copying paper to be conveyed next is stopped upstream of the transfer position and is thus prevented from being stuck with the toner. The transfer paper is reusable after the treatment of the jam. The waste of the copying paper is thus obviated.

Title: Pump for thawing snow
Inventor: HAYASHI MIKIO
IPC: E01H5/10
Filed: 1995-01-13
Abstract: PURPOSE: To make thawing of snow executable with consumption of water saved by providing a time-ratio setting means that operates for turning-on and turing-off of electric power supplied from an electric variable means to a variable speed pump and changes ratios between the duration of turning-on and the duration of turning-off in accordance with intensities of snowfall. CONSTITUTION: A signal (s) from a snowfall detector 51 is outputted as a snowfall intensity signal (w) to a comparator 54 and compared with a set value. The comparator 54 closes a switch 42 on a signal (d) when the signal (w) is larger than the set value, and supplies electric power to an inverter 43. A comparator 58 compares a pressure signal (h) on a water transfer pipe 37 detected by a pressure detector 40 with a target pressure (m), and outputs a signal (e) to a proportional integration part 59. The proportional integration part 59 outputs a velocity signal (f) to the inverter 43. In the case where the signal (h) is smaller than the pressure (m), the signal (f) increases, and revolution speed of a pump 33 is increased, intensifying the water transfer pressure. In the case where the signal (h) is larger than the pressure (m), the water transfer pressure is decreased.  A timer 56 outputs, based on the signal (w), on/off signals (c) to the inverter 43, and operation is started or stopped for controlling sprinkling of water from a sprinkling nozzle 38.

Abstract: PURPOSE:To synthesize efficiently two adjacent frequency components by setting an electric length of a transmission line so that input waves which have been divided equally into two paths from other input terminal, respectively, on an interface of an input terminal become a roughly opposite phase to each other, and the output becomes zero. CONSTITUTION:A component which has been inputted from an input terminal 1 is divided into two in an interface A, and a phase of the component which passes through a circulator 11 and reaches an interface B, of said two components is delayed by (1/4+n12)lambda based on the interface A as a reference. On the other hand, a phase of the component which phases through an interface C and a circulator 12 from the interface A, and reaches the interface B is delayed by (1/4+n13+n32+1/2)lambda based on the interface A as a reference. Said two components become an opposite phase to each other in the interface B, therefore, they are not outputted to an input terminal 2. On the other hand, a phase of the component which passes through the circulator 11, the interface B and the circulator 12 from the interface A, and reaches the interface C is delayed by (1/4+n12+n23)lambda based on the interface A as a reference, but a phase of the component which reaches the interface C directly from the interface A becomes (1/4+n13)lambda based on the interface A as a reference, and these two components become the same phase and are outputted to an output terminal 3. That is to say, all input waves from the input terminal 1 are outputted to the output terminal 3.
