Title: Amplitude modulation transmitter
Inventor: SAGAWA MASATO
IPC: H04B14/04
Filed: 1990-11-30
Abstract: PURPOSE:To prevent production of an undesired harmonic component and to reduce the distortion factor by using a high frequency distributer to input a carrier signal fed from a carrier frequency oscillator to plural high frequency amplifiers and an A/D converter. CONSTITUTION:An analog signal inputted from an A/D converter 3 is converted into a multi-bit digital signal by using a carrier frequency as a sampling frequency, a decoder 4 receives the multi-bit digital signal outputted from the A/D converter 3 and outputs a control signal. The control signal outputted from the decoder 4 applies on/off control to high frequency amplifiers 51-510. Then a high frequency distributer 13 distributes a carrier signal to the high frequency amplifiers 51-510 and the A/D converter 3, and a carrier frequency oscillator 6 applies the carrier signal to the high frequency distributer 13 to allow an output synthesis circuit 7 to synthesize output signals of the high frequency amplifiers 51-510. Thus, the production of an undesired harmonic component is prevented and the distortion factor is reduced.

Abstract: PROBLEM TO BE SOLVED: To facilitate a protection and a removal of a tube plate surface in an inlet attached prevention device mounted on a tube inlet of a feed water heater of a boiler by enabling mounting of a protective part from outside instead of conventional mounting of the protective part into the inside of the tube. SOLUTION: A water chamber 7 is divided by a partition 11 into two portions which are provided with a supply water inlet nozzle 8 and a supply water outlet nozzle 9 respectively. A multiplicity of U-shaped steel-made tubes 2 which are communicated with the water chamber 7 are mounted on a tube plate 1. On the supply-water-inlet side surface of the plate tube 1, a porous plate 3 having a multiplicity of apertures which have the same diameter at the same position as those of the tubes 2 are mounted on the surface of the semi-circular tube plate 1 by way of a gasket. The thickness of the porous plate 3 is more than 10 times greater that the inner diameter of the tubes 2 and is equal to or less than 200mm. Accordingly, peeling-off of an oxide film which is caused by the generation of a vortex flow occurs only on the porous plate 3 so that the tubes 2 are prevented from becoming thin.  At the same time, the surface of the plate tube 1 is protected and the replacement of the porous plate 3 is facilitated.

Title: Delay controller and sound image controller
Inventor: KUWANO TAKATSUGU
IPC: H04S1/00
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To change delay at high speed without generating any noise by knowing the change of delay coefficient, holding a non-changed coefficient, outputting a 1st signal delaying an input signal from the outside just for the delay designated by the non-changed coefficient and a 2nd signal delaying the input signal just for the delay designated by the changed coefficient, and mixing both signals. SOLUTION: A delay change detecting means 11 checks whether the delay coefficient from the outside is changed from the delay coefficient perceding for one sampling cycle or not and outputs the result as a delay quantity change detecting signal A. When the delay coefficient from the outside is not changed, this delay change detecting signal A becomes '0' but when the delay is changed, this signal becomes '1'. When the delay from the outside is changed, a delay detecting means holes the delay coefficient before that change. A cross fade mixing means 13 outputs the input signal after delaying it corresponding to the delay to be changed.

Title: Method of manufacturing silicide structure
Inventor: KA SOGI
IPC: H01L21/336
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a silicide structure which is more improved in quality and where a leakage current is prevented from occurring. SOLUTION: A method of manufacturing a silicide structure is that the silicide structure is self-aligned and prevented from increasing in sheet resistance due to a reduction in a wire width by taking advantage of the specific characteristic of cobalt in which cobalt moves downward to react on silicon atoms. Furthermore, the characteristics of silicon atom in which silicon atoms move upward to react on titanium is also utilized. Titanium induces the upward movement of silicon atoms. A titanium layer is used as a barrier layer, by which cobalt acts less on silicon atoms, and a leakage current is prevented. A silicide multilayered structure is kept stable in resistance and capable of preventing a leakage current from occurring.

Title: Hybrid electric vehicle driving main electric motor arranged between battery and an auxiliary power source in accordance with charged state of battery
Inventor: LYONS ARTHUR PAULL
IPC: B60L50/15
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To make simple and effective the operations and operating characteristics of a hybrid electric vehicle. SOLUTION: Batteries 20, when they are in a charged state between a partial charging and full charging, suppress capacity of the charging of the batteries 20 with an auxiliary power source 16 and from dynamic braking. The shortage between the demand of a main electric motor 40 and energy obtained from the auxiliary power source 16 is supplied from the batteries 20 depending on their charged state. When the batteries 20 are almost in a fully charged state, the whole amount of the shortage is supplied from the batteries 20. If they are almost in a fully discharged state, nearly no energy is supplied by the batteries 20. In a charged state between nearly full charging and nearly full discharging, the batteries 20 supply the amount of energy simply in compliance with the charged state.  If the batteries 20 is in a nearly full charged state, the charging of the batteries 20 from the auxiliary power source 16 is decreased during dynamic braking. The amount of energy to be returned during dynamic braking is controlled by controlling the conversion efficiency of the main electric motor 40 working as a generator.
