Title: Process for long-term storage of tangle
Inventor: NAKAZONO SHIYUUZOU
IPC: A23L17/60
Filed: 1984-02-03
Abstract: PURPOSE:To enable the long-term preservation of tangle without lowering the seasoning effect of tangle, by putting tangle into an indirectly heated animal or vegetable oil, evacuating the oil keeping the oil temperature at a constant level, and removing the oil from the tangle. CONSTITUTION:An animal or vegetable oil is heated indirectly in a closed vessel (preferably at a temperature to cause the ready coagulation of water-soluble protein in the tangle), and tangle is put into the oil. When the vessel is evacuated while keeping the oil temperature, the tangle is dehydrated by the substitution of the water in the tangle with the oil mixed with the salt attached to the surface of the tangle. The dehydrated tangle is deoiled by pressing or centrifugal separation. EFFECT:The thermal decomposition of sodium L-glutamate in the tangle can be prevented because the heating is carried out at a relatively low temperature. Since the salt-containing oil is impregnated into the tangle to effect the salting of the tangle, the water-soluble protein in the tangle is coagulated and stabilized and the putrefaction of tangle is prevented.

Filed: 1995-02-07
Abstract: PURPOSE: To obtain a control circuit of an inverter, which is constituted in such a way that the output of the inverter is supplied to a system. CONSTITUTION: A phase correction circuit 14 is installed in such a way that a system current correspondence value which is output from a system current detector 6 and an inverter output voltage correspondence value which is output from an inverter output voltage detector 5 are input to the phase correction circuit, that the values are sampled respectively at a constant cycle so as to compute the time difference of respective zero-corssing points and that a correction signal corresponding to the time difference is created. A reference signal which comprises a phase difference corresponding to the correction signal is created by a PLL circuit 11. Then, a control signal by which an inverter output current correspondence value to be output from an inverter output current detector 4 is made to agree with the reference signal is created by a differential amplifier 12. On the basis of the control signal, a PWM control signal is created. Consequently, since the phase of the output current of an inverter can be controlled so as to agree with the phase of a system current, the power factor and the efficiency of the inverter are not dropped due to a load change.

IPC: B41J21/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a recorder capable of excellently recording plural images on one medium to be recorded even in the case of including the images of different sizes. SOLUTION: When an Nin1 function is specified from an operation part 13 and copying is to be performed, the image of the first sheet of an original is read in a read part 14 first and allocated to the area of 1/N of the medium to be recorded. In the case that the image size of the second and succeeding sheets of the original is large, when it is settled in a free area, allocation is performed as it is. When no more free area is present, recording output is performed to the medium to be recorded in a recording part 15 even when the number of the images does not reach N. Thus, legibility is guaranteed without abnormally reducing the images of a large size.  Also, when the images of the size smaller than the image size of the first one are included in the second and succeeding images and the succeeding images are settled in the free area even after the N pieces of the images are aggregated, they are aggregated. Thus, more than N pieces of the images are aggregated and recorded and outputted to the medium to be recorded in the recording part 15.
