Title: Thermal sterilization of sealed container in retort
Inventor: IKEDA MASAOMI
IPC: B65B55/06
Filed: 1985-05-02
Abstract: PURPOSE:To prevent the degradation of the content in a sealed container made partially or wholly of a plastic in the retort sterilization process, by substituting the air in the retort oven with an inert gas. CONSTITUTION:A sealed container containing food, etc., as main contents and composed of a body wall part, a bottom wall part and a lid wall part at least one of them is made of a plastic or a laminate of plastic and paper, is thermally sterilized in a retort oven. Then air in the retort oven is substituted with an inert gas at least in the period wherein the temperature in the retort oven is <=50 deg.C. Since the oxygen is absent in the atmosphere in the retort oven in the period heated at >=50 deg.C above which the barrierness of the resin layer is reduced remarkably, the intrusion of oxygen into the container can be inhibited to prevent the degradation of the content.

Title: Preventing valve for mixing
Inventor: NISHIKAWA ICHIROU
IPC: C12C13/00
Filed: 1978-08-04
Abstract: PURPOSE: To provide a valve for preventing mixing, wherein when the valve is closed, vertically arranged two independent flow pahts are formed and also a hollow chamber is formed between a first valve element and a second valve element, so that fluid leaked from one of the flow paths is positively prevented from intruding into other flow path.  
     CONSTITUTION: When the present valve is in a closed position, a spindle 11 is pushed down by an actuator 26 to push a first valve element 6 through an O-ring 8 against a valve seat 4. A second valve element 7 is pushed through an O-ring 9 against a valve seat 5 by means of pushing force of a spring 13 and the pressure of liquid flowing in a upper flow path 1. In this closed position the upper flow path 1 and a lower flow path 2 form independent flow paths each other, and in a case where one of liquids in the upper and lower flow paths leaks through the valve seat 4 or 5, the leaked liquid will flow into a hollow chamber 16 and will be discharged outside of an opening 19 through oblong slots 17 and a vertical channel 18, and thus the leaded fluid will be prevented from intruding into other flow path.

Title: Induction heating cooking apparatus
Inventor: FUJISHIMA KUNIHIRO
IPC: H05B6/12
Filed: 1988-04-19
Abstract: PURPOSE:To protect an inverter circuit in the period from the power being shut momentarily, i.e. in that short period when a momentary shutting-off can not be sensed, by sensing drop of the source voltage, and lowering the oscillation output of the inverter. CONSTITUTION:When a momentary shutting-off is made for ex. as short as 1msec approximately, the input to a comparator is left as it is while the output is maintained in H level condition, wherein no resetting can be applied to a start stopping circuit 19 to permit lasting of normal oscillative condition. The momentarily shut-off wavform P1 is, however, supplied to a transistor Q2 via transistor Q1, and the collector output P0 becomes at L level without any delay substantially. Accordingly a pulse width adjusting signal PY is sunk to cause decrease of the pulse width of an ON pulse emitted from a pulse width control circuit 18. Accordingly the ON time of a switching element 11 is still short even though resumption of supplying the power causes abrupt current supply to the inverter circuit, so that there is no risk of boosting the resonance voltage to lead to provision of a safe value.

Abstract: PURPOSE:To faithfully reproduce original picture data by matching picture data to this data, comparing a difference between this data and output data different in the number of maximum gradation from this data with a threshold and processing the output data based on the compared value. CONSTITUTION:The inputted picture data G is respectively compared with 8, 16, 24, 32, 40, 48, 56 in seven comparators 1, when it is larger, a '1' output is issued and when it is smaller, a '0' output is issued. In the outputs of seven bits, the number of '1' in the seven bits is counted by a counter 2 and this counted value is multiplied by 8 in a multiplier 3. Then, the output of the multiplier 3 is subtracted from the number of the gradation of the picture data G in a subtracter 4. Further, the output of the subtracter 4 is compared with a value outputted from a binarization threshold data storing memory 6 through a counter 5 from a picture block in a comparator 7, when the former is larger than the latter, a value obtained by adding 1 to the output value of the counter 2 in an adder is outputted as output picture data S.

Title: Sheet feeder
Inventor: SUGIMURA HIDEO
IPC: B41J13/02
Filed: 1987-04-21
Abstract: PURPOSE:To hold a recording sheet accurately at recording position without loosening the sheet when the sheet is fed forwardly, by providing an interlocking means between a platen and a bail roller and interlocking the bail roller through a unilateral clutch means only when the platen is rotated forwardly. CONSTITUTION:A spring 13 for unilateral clutch is arranged between a large gear 11 and a platen shaft 2. The clutch spring 13 is wound around the platen shaft 2 when a platen 1 rotates forwardly (in the direction A). A recording sheet 5 is held through frictional force F against the platen 1 and fed in the direction B, and frictional force F functions between the recording sheet 5 and a bail roller 6 which contacts with the recording sheet 5 and rotates with slightly higher circumferential speed than that of the platen 1 in the direction C. Since the frictional force F contributes to feed out the recording sheet 5 in the direction B, the recording sheet 5 does not loosen in front of the bail roller 6 and can be held at recording position under stretched state. Consequently, the lowering of the recording quality can be prevented.

Filed: 1985-05-07
Abstract: PURPOSE:To improve resolution and to utilize the quantity of light by forming curved surfaces on an opposite and/or a total reflecting surface so that luminous flux which is reflected totally is less than luminous flux incident from the surface opposite from the total reflecting surface. CONSTITUTION:Numbers of prisms 1 which have total reflecting surfaces 1A and opposite surfaces B are formed on a projection side. Then, a lenticular lens surface 1 which extends vertically is formed on an observation side and horizontal diffusivity is obtained by this lenticular lens surface 1D. In this case, the rays of light incident on the rear of a screen at an acute angle are projected on an observation surface uniformly and efficiently because of the shape of the prisms and the operation of total reflection, so when a backproject screen is employed, a projector as a light source is positioned slantingly behind to reduce the size of the whole projection device, and the backproject screen which is uniform and bright and has superior resolution is obtained.

Abstract: PURPOSE:To obtain a good picture with no disorder of an electric field, by providing a metal for giving electric connections to respective conductive supporting rods between the terminal part of the front plate sides of fixing plates and the terminal part on the front plate side of a supporting wall while providing a means for electrically connecting a screen to the metal member. CONSTITUTION:A metal member 5 is arranged between an end surface 2a on the front plate side of a supporting wall 2 and an end surface on the front plate sides of fixing plates 3. Accordingly, it can be prevented that the metal member 5 bends due to a thermal expansion difference between the supporting wall 2 and the metal member 5 to protrude rather to the front plate side than to the end surfaces of the fixing plates 3 so as to disturb an electric field and to generate landing shift of an electron beam. Further, a terminal 5e is formed at the end of the metal member 5 and the terminal 5e and the terminal 8 of a screen 7 are connected to a terminal 9 so as to enable the screen 7 and the conductive supporting rods 4 to be equipotential.
