Patent JP-S62174167-A (JP)
Title: Image forming device
Inventor: WATANABE JUNJI
IPC: B41J25/316
Filed: 1986-01-29
Abstract: PURPOSE:To enable one-sight confirmation of whether or not paper can be inserted by setting a head, a paper guide and a paper holding roller on an upper cover and the upper cover to be unlocked and displaced upward if a push button is pressed. CONSTITUTION:For instance, in a serial scanner printer, if a push button 62 provided at a rear right end of the upper surface of a main unit is pressed, lock pins 85a, 85b are removed from lock members 84a, 84b respectively. As a result, an upper cover 55 is rotated and displaced in an arrow direction by spring force with an axial fulcrum 64 as a supporting point. At the same time, a paper guide 59, a thermal head 56, a paper holding roller 60, etc. are displaced upward together with the rotation and displacement of the upper cover, opening a paper carrying channel. Paper P inserted through a paper inlet 35 smoothly passes through an image forming section 57, butting against a stopper 64. Thus the tip is positioned and if the upper cover 55 is pressed, said cover will be locked to an original condition by the lock pins 85a, 85b thus restoring a prearranged printing state automatically.

Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling a temperature of feeding hot water in a hot water feeding device for restricting an over-shoot phenomenon in which hot water having its temperature higher than a set temperature with surplus heat in a heat exchanger during re-feeding of hot water is fed out at first and an under-shoot phenomenon in which cold water is fed out subsequent to the operation. SOLUTION: A bypass valve 16 in a bypass passage 14 for bypassing a heat exchanger 10 is opened when hot water is fed out again and then cold water is fed out together with hot water flowed out of the heat exchanger 10. When the bypass valve 16 is closed, a valve closing timing is set in advance at a plurality of stages in correspondence with a detected temperature within the heat exchanger 10 by a temperature sensor 18 and then the bypass valve 16 is closed in a proper timing in response to a level of the detected temperature.

Abstract: PURPOSE:To prevent en-st by controlling an engine speed to a designated value during idling when a variable-capacity compressor is operated and making the compressor capacity less than a designated value when the engine speed is lowered to a designated speed. CONSTITUTION:When compressor operation judging means detect operation of a compressor and idling detecting means detect idling of an engine, idle control means control the engine speed to a designated value according to the above detection signals.

Title: Thermistor composition
Inventor: TOZAKI HIROMI
IPC: H01C7/04
Filed: 1978-02-22
Abstract: PURPOSE: To provide a low resistance thermistor with less secular changes in resistance and having a higher thermistor constant by sintering at least two of oxide powders of Mn, Co, Ni, Fe and Al and RuO 2 .  
     CONSTITUTION: This thermistor material is composed of a conjugated metal oxide made of at least two of Mn 3 O 4  (or Mn 2 O 3 ), Co 3 O 4  (or Co 2 O 3 ), NiO, Fe 2 O 3  and Al 2 O 3  and RuO 2  powder, provided that the Ru content is less than 40% in terms of atoms in the above composition. This metal oxide component is crushed, mixed together and heat-treated. The material thus heat-treated is crushed again, shaped in a mold and heat-treated to yield a ceramic with a high thermistor constant. The reason why the Ru content should be less then 40% in terms of atoms in the composition is that Ru contents over this value reduces the temperature dependence of the thermistor resistance eventually to deteriorate the thermistor performance.

Title: Die-casting core
Inventor: NOJIRI TERUJI
IPC: B22D17/22
Filed: 1979-02-22
Abstract: PURPOSE:To eliminate the likelihood for damaging working blades and improve the thickness accuracy of the casting by providing male and female engaging portions between the core prints integrally protrusively molded with enlarged portions and sand core bodies and bonding and binding the sand core bodies to the core prints. CONSTITUTION:Since enlarged portions 7, 8, 9, 12, 13 become the positioning jigs for die-casting sand core bodies 1, 2 for core prints 5, 6, the spacing accuracy between the core bodies 1, 2 improves. Even if the molten metal infiltrates the surface layer part of the core bodies 1, 2 and the mixed layer of the molten metal and sand is formed at the time of performing die-casting by sandwiching and fixing the cores 1, 2 between dies 18, 19 and injection the molten metal into the cavities between the dies and cores, there is no likelihood that the sand enters the contact portions A between the casting and enlarged portion. Hence, even if the end face on the core print 5 side of the casting is machined, the machining margin S is about 1mm and is smaller than the thickness H of the enlarged portions and therefore there is no likelihood of damaging the working blades. In addition, the core bodies are supported to the core prints 5, 6 by way of the male and female engaging portions by the protrusions 15, 16, 17, 5', hence the casting of the accurate size may be obtained.

IPC: C22C1/02
Filed: 1989-01-27
Abstract: PURPOSE:To effectively admix the additives by providing an undulated part on the bottom of a crucible to generate turbulent currents of molten metal. CONSTITUTION:On the inner surface of a bottom 2 of a crucible 1, a turbulent current generating undulated part 5 is provided which consists of two or more wavy, step-like or other type of protruding and recessed parts. When additives are added into an alloy, which is turned into molten matrix, in the crucible 1, and a kneading rod 6 is put into the crucible and rotated, the molten alloy begins to rotate in the horizontal direction, however, part of molten alloy facing the bottom 2 of the crucible 1 strikes against the turbulent current generating undulated part 5 provided on the bottom 2, causing turbulent currents to be generated there. That is, irregular up-and-down currents of the molten alloy on the bottom 2 is created and collides to the upper horizontal currents, so that the additives are distributed through out the molten alloy in the crucible 1. In addition, effective agitating and mixing are carried out by the cooperative action of a rotary vane 6a which stimulates the molten alloy current to move up and down.
