Title: Amplifier circuit for transmission
Inventor: ITOU HITOSHI
IPC: H04M1/60
Filed: 1979-06-11
Abstract: PURPOSE:To prevent the click tone accompanied with the hook-on and -off of a handset, by connecting a discharging resistor in parallel with the bypass capacitor and connecting a diode between the discharging resistor and the DC bias circuit of the current amplifier circuit. CONSTITUTION:In parallel with the bypass capacitor C1, the discharging resistor ra or diode Da is provided. Further, when the handset M is removed through the deinsertion of the plug of the headphone, since the residual charge of the capacitor C1 and the DC power supply current do not flow in the bias circuit including the resistor (r) because of the diode Da, the transistor TR is immediately OFF. Simultaneously, the charge on the capacitor C1 discharges through the resistor ra and the voltage across the capacitor C1 is 0. With this state, when plug-in is made again, current starts to flow in the current amplifier circuit to cause click, but it is bypassed with the capacitor C1 and the amplitude is attenuated.

Title: Crosstie
Inventor: SAEGUSA OSAO
IPC: E01B3/16
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a large and lightweight crosstie by installing it only at a rail joint on one side without connecting parts corresponding to right and left rails with each other and forming it into a metal box. SOLUTION: A crosstie 12 for a rail joint is installed only in the joint 3 of one rail without connecting parts corresponding to right and left rails 1, 2 with each other. Therefore, no electrical insulation problem occurs in a railway having a track circuit. The crosstie 12 is formed into a flat square box with an opening in the bottom, using a metal material such as a ductile cast iron so that ballast may be packed into the inside through the opening at the bottom. The retention of a gauge by connecting the right and left rails 1, 2 with each other is made by ordinary crossties installed nearby. Thus a large but lightweight crosstie corresponding only to a rail joint can be formed.

IPC: H01L27/115
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To form a capacitor electrode of high adhesion by forming an electrode having a third conductive film, that contains a second metal which is different from a first metal. SOLUTION: For example, a lower electrode 36 of Pt/Ir/IrO2 structure is formed by depositing sequentially an IrO2 film 30, an Ir film 32 and a Pt film 34 on a silicon oxide film 28. On a ferroelectrics film 38, an upper electrode 46 of Pt/Ir/IrO2 structure is formed by depositing sequentially an IrO2 film 40, an Ir film 42 and a Pt film 44. Namely, for the lower electrode 36, instead of a Pt film 34 not being deposited directly on an IrO2 film 30, an Ir film 32 which is not an oxide film is sandwiched between the two. Due to this structure, adhesion of the Pt film 34 is improved, and peeling of the Pt film 34 can be prevented. Similarly, by adopting Pt/Ir/IrO2 structure for the upper electrode 46, adhesion of the Pt film 44 is improved, and peeling of the Pt film 44 can be prevented.

Title: Apparatus for processing photosensitive material
Inventor: YAMAMOTO TAKERO
IPC: F26B13/10
Filed: 1993-03-31
Abstract: PURPOSE:To provide the apparatus for processing photosensitive materials which prevents unequal drying by subjecting photosensitive materials to uniform heating for the purpose of accelerating evaporation by heat rollers over their entire surface. CONSTITUTION:The films 20 in a drying section 50 are first transported by means of two pieces of transporting rollers 44 which come into contact alternately with the front and rear surfaces of the films. Drying air is blown to the films, by which the water drops remaining particularly at the front ends or rear ends in the transporting direction of the films as well as the water drops, etc., remaining nonuniformly over the entire part of the films are made into a relatively uniform state. The evaporation is accelerated on the films by four pieces of the heat rollers 60 and the atmosphere contg. much moisture is expelled by the drying air from blow-off pipes 47, by which the evaporation is further accelerated. There are no unequal water drops at this time and, therefore, the partial delay or advance in evaporation does not arise and the evaporation is accelerated uniformly over the front surfaces of the films.

Abstract: PURPOSE: To make the bias force of a bias means for biasing a stylus of a touch probe for measuring position of work piece to a prescribed position adjustable by displacing the bias means a little and, at the same time, to reduce the total length of the probe. CONSTITUTION: A spring 40 having a small spring constant and another spring 42 having a large spring constant are serially combined together by respectively connecting the springs 40 and 42 to each other between a shuttle 44 for adjusting bias force and an intermediate member 48 and between the member 48 and a stylus supporting member 14. The spring 40 is energized in advance and, in an adjusting extent, only the spring 42 is made to be extended and contracted. When a stylus 22 is displaced largely, on the other hand, both springs 40 and 42 are deformed. When the springs 40 and 42 are deformed, the bias force becomes weaker than that when only the spring 42 is used and the stylus is not damaged. In addition, the intermediate member 48 is partially put in and on the springs 40 and 42 so as to reduce the length of a probe.
