Title: Floor plate material for railroad crossing
Inventor: UMEMOTO HIROYUKI
IPC: E01C9/04
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To easily scale off snow or ice stuck on the surface of a floor plate by elastically deforming the surface by passing vehicles by laminating a urethane layer in which rice hulls are dispersed, on a base material and forming a number of small projections on the surface. SOLUTION: An about 10 mm thick urethane layer 44 is overlapped on the upper face of a base material 42 and a number of small projections 44a are formed on the surface of the urethane layer 44 by using a number or rice hulls 46 dispersed in the urethane layer 44 to constitute a floor plate 40 for a railroad crossing. In this way, when vehicles pass thereon, the surface of the urethane layer 44 is elastically deformed to easily scale off snow or ice stuck on the surface and prevent the surface of the floor plate 40 from forming an Eisbahn- shaped state. When the urethane layer 44 is laminated on the base material 42 provided with grooves on the upper face, tires can be prevented from slipping owing to the edge effect of the grooves. Composite wooden material, FRP, concrete, metal, etc., except wooden material can be used as the base material 42.

Title: Numerically controlled oscillator
Inventor: KANEZUKA NAOMI
IPC: G06F1/02
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To make the circuit scale small by reducing data to be stored in a ROM being a component of the numerically controlled oscillator. SOLUTION: An address generating circuit 1 multiplies a multiple of 1/m with a phase mθ (0<=θ<=θmax, θmax=π/2m) and provides an output of a ROM address θ. A ROM 2 stores functions cosθ, sinθ corresponding to the phase θ(0<=θ<=θmax) and configures a lockup table that outputs the functions cosθ, sinθ. A phase multiple circuit 3 obtains cos(mθ), sin(mθ) multiplying a phase of the cosθ, sinθ being an output of the ROM 2 by a multiple of (m) by using a recurrence formula using the addition theorem of the trigonometric functions and provides an output of the result.

Title: Passivation film structure of semiconductor device
Inventor: SATO NOBUYOSHI
IPC: H01L21/318
Filed: 1990-03-19
Abstract: PURPOSE:To prevent cracks of wiring pattern with excellency in acid resistance, alkali resistance, and water resistance as well as with less wafer warps by making silicon oxide nitride film thicker than a silicon nitride film in a double- layer structure where the lower layer is a silicon nitride film and the upper layer is a silicon nitride film. CONSTITUTION:A silicon oxide nitride film 1 is formed thicker than a silicon nitride film 2 in a double-layer structure where the lower layer is a silicon oxide nitride film and the upper layer is a silicon nitride film 2. Since the silicon nitride film 1 is formed on the surface of a semiconductor device at a low temperature (about 300 deg.C) by plasma CVD or the like, hillocks caused by a high temperature (about 400 deg.C) can be prevented in a wiring layer. The silicon oxide nitride film 1 can suppress wafer warps and diminish stress migration because of low stress, thereby preventing cracks in the wiring zone of a semiconductor device. This structure can provide high-reliability semiconductor devices excellent in acid resistance, alkali resistance, and water resistance.

Title: Processing method for base
Inventor: ORIGASA TOSHIYUKI
IPC: C08J7/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide an effective processing method for a base containing a formaldehyde resin with exhaling quality and lessen the exhalation quantity of formaldehyde contained in the base. SOLUTION: First, a base 1 is irradiated with an ionizing radiation 4 and is contained into a bag made of a sheet composed mainly of a resin with gas barrier properties and containing a formaldehyde scavenger and the bag is airtightly sealed. Under this sealing condition, the base 1 is left alone for a specified time. Alternatively, a leaf sheet of the same sheet quality and the base 1 are alternately lapped over each other and are left alone under this lamination state for a specified time. Further, the exhalation and emission of the formaldehyde from the base 1 is promoted by irradiation with the ionizing radiation 4. Next, the formaldehyde emitted from the base 1 is scavenged by a bag-like or a leaf-like sheet to be removed. This processing method neither adversely affects the performance of the base 1 nor the manufacturing of the base 1 and the suitability for post-processing.

Title: Ring oscillator
Inventor: OGAWA SUMIO
IPC: H03K19/094
Filed: 1987-03-23
Abstract: PURPOSE:To contrive to decrease the power consumption by connecting a two- way constant current drive means in cascade between two transistors (TRs) constituting an inverter so as to eliminate the through-current of the inverter. CONSTITUTION:When the 1st and 2nd input terminals go both to a low potential in a no through-current inverter 1, since a P-channel MOSFET Q1 is turned on, a 1st output terminal is charged immediately and reaches a high potential, but a 2nd output terminal is charged slowly due to the current limit by a constant current circuit section 4 and reaches a high potential with a delay to the 1st output terminal. Thus, the 1st input terminal reaches a high potential in the no through-current inverter 2 earlier than the 2nd input terminal, if the current limit is sufficiently large, after the P-channel MOSFET Q3 is turned off at first, the N-channel MOSFET Q4 is turned on and the both are not simultaneously turned on and no through-current flows to a no through-current inverter 2. Thus, low power consumption is attained.

Title: Exposing device for copying machine
Inventor: IBUCHI YOSHIAKI
IPC: G03G15/04
Filed: 1987-03-23
Abstract: PURPOSE:To prevent leakage of light even if copying is executed by opening an original cover by disposing a device for detecting the rear end of an original to the position forward of a position where the original is irradiated in the moving direction of said device. CONSTITUTION:A control circuit 5 executes the next cycle if a cover switch 9 is open when a user pushes a copy switch 10. Namely, a copy lamp 2 is turned on and a driving signal is outputted to a driving circuit 12 for a moving device to drive the moving device for the irradiation position. An LED 4a which is the device for detecting the rear end of the original is then turned on and the output of a phototransistor Tr 4b is monitored to find the rear end of the original. The circuit 5 turns off the lamp 2 upon lapse of the prescribed time after the detection when the rear end 1a of the original is detected. The leakage of the light to the outside of the original region is thereby prevented even if the copying is executed while the original cover is held open. Since a black solid state is not attained in regions except the original region, the waste of a toner is eliminated.
