Filed: 1988-08-09
Abstract: PURPOSE:To improve thermal efficiency by exposing the outer peripheral shell plate of a heat exchanger to washing water under the water level inside a hot water tank to heat water and retain its heat, while sending fresh air into an air chamber formed on the periphery of the combustion-chamber partition wall of a combustion chamber to inject the air as a high temperature air. CONSTITUTION:As a washing object is conveyed to a position B, a washing hot water in a hot water tank 2 is injected via a washing pipe 28, a nozzle header 8, and a nozzle installing pipe 4. Nextly, as the object is conveyed to a position C, a high temperature water which is sent into a heat exchanger 13 by means of a pump 15 and heated is jetted out of the nozzles of a nozzle installing pipe 6 to carry out rinsing. Then, water remaining on the surface is dried by a high temperature air jetted out of a high-temperature air injecting body 7. By this washing machine, since the outer peripheral shell plate 26 of the heat exchanger 13 is exposed under the water level of the washing hot water inside the hot water tank 2, the heating and heat retention of the hot water can be effectively carried out. Also, air is sent into an air chamber formed around the combustion chamber partition wall 30 of a combustion chamber 12 by means of a blower 32 to be used for finish drying as a high temperature air, thereby enabling the effective use of heat.

Abstract: PURPOSE:To adaptively vary the bit allocation of vector quantization by allocating code vectors to respective steps including the final step of a binary tree and executing search until the step of the binary tree corresponding to the number of bits allocated to output data in a vector quantizer which executes binary tree search and encoding. CONSTITUTION:A vector quantizer 30, which executes the binary tree search and encoding, is composed of a code book 20 storing the respective code vectors to be allocated to the respective nodal points of the respective steps in the binary tree, and digital signal processor (DSP) 15 to execute the search until the step of the binary tree corresponding to the number of bits allocated to the output data. Since this DSP 15 stops the search in the middle step of the binary tree corresponding to the number of bits allocated to the output data, the number of bits is adaptively varied for a vector quantizing output (index). Based on the vector of input data through an I/O port 12 and bit allocation information through an I/0 port 13, the USP 15 controls the respective code vectors, which are allocated to the respective nodal points of the respective steps, and the index corresponding to the code vector to be read out from the code book 20.

IPC: F24F11/02
Filed: 1981-12-07
Abstract: PURPOSE:To enable to perform a comfortable heating, by a method wherein, in a subject circuit provided with a room temperature thermostat circuit for controlling turning-ON and OFF of a compressor, a blower is operated in synchronism with start and stop of the compressor, and when a room temperature thermostat is OFF, the operation of the compressor and the blower are controlled by a period timer. CONSTITUTION:In case a heating side is selected by bringing a cooling/heating change-over switch 21 into ON, if an operation switch 20 is brought to ON, a blower 9 and a 4-way valve 10 for change-over of cooling and heating are turned ON to start a heating. In which case, if a switch for a control circuit 22 is ON, room temperature rises due to heating, and when an output of a comparator 27 for comparing room temperature with a set temperature inverses, a compressor 8 stops operating by means of a microcomputer 18, and the blower 9 stops operating tens seconds later. When in the above condition or a thermostat circuit including the comparator 27 is OFF, the compressor 8 and the blower 9 are controlled by a period timer, not shown, and this realizes a comfortable heating without a cold air feeling.

Title: Liquid-filled vibration control device
Inventor: MIYAKE KAZUTOSHI
IPC: B60K5/12
Filed: 1992-07-01
Abstract: PURPOSE:To provide a liquid-filled vibration control device of high performance suitably usable even in a high temperature atmosphere. CONSTITUTION:A liquid-filled space closed by a rubber elastic body 3 is partitioned by a partition plate 5 with a throttle passage 51 formed therein so as to form a pair of liquid chambers A, B. A coil spring 6 is provided between the partition plate 5 and an upper plate 1, and the lower end of the coil spring 6 is fixed to a receiving member 7 sliding on the recessed spherical face 5a of the partition plate 5. Since the static load of a vibrator is suppoted by the coil spring so as to be hardly applied to the rubber elastic body 3, the rubber elastic body 3 is not deformed in the distorted state by the static load nor degraded even in a high temperature atmosphere because of the use of heat resisting rubber. Also, even when the attitude of the vibrator changes to cause the change of the opposed attitude of the upper plate 1 to the partition plate 5, the coil spring 6 is rotated around a fixed point C at one end without changing its attitude to the upper plate 1. Vibration is thereby always inputted to the coil spring 6 from the axial direction to avoid the lowering of its durability.

CONSTITUTION:An element isolated Si substrate 1 having an n<+> layer 4 and an Si electrode 3 is covered with thin films Si3N4 5 and SiO2 6. Poly Si is deposited and a wiring layer 7 is patterned using a resist mask 8. A part of the wiring layer 7 is immediately above the electrode 3 while the other end is separated from the n<+> layer 4. The SiO2 6 is etched away using HF solution as well as the resist 8 and the wiring 7 as masks and then the resist 8 is removed to form the SiO2 6 film beneath the wiring layer 7 by self alignment. Next, SiO2 9 and poly Si 10 are laminated and a wiring 10 is formed using another resist mask 11 immediately above the electrode 3 and the wiring 7 while the end is separated from a connecting hole formation part. Next, the SiO2 9 is etched away using the resist 11 and the wiring 10 as masks and then the resist 11 is removed to form the SiO2 9 only on the part beneath the wiring 10 by self-alignment.

Title: Method of adding hot water to bathtub
Inventor: ADACHI IKURO
IPC: F24H1/00
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To perform filling of hot water in a prescribed amount by measuring the time elapsed from the start of heating provided by a heat exchanger and inhibiting addition of hot water to a bathtub based on a remaining amount of hot and cold water until a period of time elapsed from the start of heating exceeds a predetermined time. SOLUTION: Temperature sensors 41, 42 detect inlet and outlet temperatures of hot and cold water 11 circulating in a heat exchanger 3, and a hot water filling mechanism 6 is connected between the temperature sensor 42 and a bathtub 1 through a shut-off valve 61 such that when the shut-off valve 61 is opened, hot water heated by the hot water filling mechanism 6 is supplied to the bathtub 1 to automatically fill the bathtub 1 with a set amount of hot water.  In the case where hot and cold water 11 is heated by the heat exchanger 3, when a period of time elapsed from the start of heating is short, a quantity of heat transferred to the hot and cold water 11 is taken by, a circulating path while the hot and cold water 11 is returned to the bathtub 1 through the circulating path, so that speed of temperature rise detected by the temperature sensor 41 becomes less and so an error with respect to the remaining amount of hot water becomes great. Thus until a period of elapsed time exceeds a predetermined time and the circulating path is put into a thermally equilibrium, addition of hot water based on the remaining amount of hot water is not effected.
