Title: Resin-coated sand grains for forming mold and mold formed of this sand grain
Inventor: KAI ISAO
IPC: B22C1/02
Filed: 1981-02-23
Abstract: PURPOSE:To improve collapsibility by lowering the residual stringth after casting of a mold consisting of the coated sand obtd. by coating raw material sand with a composition consisting of a curable resin and a halogen-contg. org. compd. CONSTITUTION:A composition consisting of 0.3-10pts.wt. a curable resin and 0.001-10pts.wt. a halogen contg. org. compd. based on 100pts.wt. raw material sand is mixed with said sand and the mixture is kneaded, whereby the raw material sand grains are coated with the composition. In this case, the halogen org. compd. is decomposed by heating, and the cracked gas accelerates the carburization of the curable resin. Hence, the mold formed of this coated sand maintains the superiority of moldability and the heat resistance required in the stage of casting during casting, but after the casting, it degrades its residual strength and improves collapsibility considerably.

IPC: G11C11/44
Filed: 1985-02-13
Abstract: PURPOSE:To prevent readout reliability from deteriorating even if there is slight variance in signal readout timing by using a superconduction latching circuit which uses a Josephson junction element as a read circuit and the 1st and the 2nd write circuits. CONSTITUTION:The read circuit 11, the 1st write circuit 12, and the 2nd write circuit 13 are latching circuits using a Josephson junction (JJ) element which is short in switching time at extremely low temperatures. A current pulse of a signal arriving through a delay line 14 is inputted to the read circuit 11 and a threshold bias current for determining the threshold value with which it is decided whether the signal is '1' or '0' is supplied to a terminal S1. The 1st write circuit 12 is activated with a bias current applied from a terminal B2 at time t1 after t0 and the 2nd write circuit 13 is activated with a bias current applied to a terminal B3 before time t1. Therefore, the 2nd write circuit 13 begins to flow an output current to a delay line 15 at the time t1 when the 1st write circuit 12 outputs '1', so that the output current which has pulse width t2-t1 is outputted to the delay line 15.

Title: Pusher for sintering furnace
Inventor: NAKAMURA YASUHIRO
IPC: F27D3/04
Filed: 1985-02-13
Abstract: PURPOSE:To prevent a sintered body from being carburized and to prevent the early consumption of a graphite pusher for a sintering furnace by coating at least the surface of the pusher to be imposed with the sintered body with a metallic or plastic layer.

Title: Corona discharge controller for electrophotographic copying device
Inventor: OKU JUNTARO
IPC: G03G15/02
Filed: 1990-02-07
Abstract: PURPOSE:To obtain a corona discharge controller which makes an electrophotographic copying device small in size and light in weight and simultaneously improves the economics thereof by making a transformer for electrostatic charge and for transfer common. CONSTITUTION:A high voltage from a common transformer 35 is impressed on an electrostatic charger 32 and a photosensitive body 31 is electrostatically charged. On the other hand, the high voltage from the transformer 35 is also impressed on a transfer charger 34. However, since a control grid 38 is made to be grounded potential by the on-action of a switching element, the photosensitive body 31 is positively and electrostatically charged by the charger 34 very little and there is not a trouble. Then, since the switching element is controlled to be turned off in timing that a paper is passed through the charger 34, the grid 38 attains the prescribed potential by a constant-voltage element 39 and transfer to the paper from the photosensitive body 31 is realized. Thus, the corona discharge controller which makes the electrophotographic copying device small in size and light in weight and simultaneously improves the economics thereof is obtained.

When the photographic sensitive body 1 is used in an image forming device performing development by making a toner layer on the roller 40 brought unto contact with the photoreceptor 1, the horizontal black stripe on the leading end of the transfer paper occurring when the impressed voltage on the roller 40 is switched can be prevented, so that the image having excellent image quality and density can be formed. Besides, since the multistage control of an impressed voltage is not required, the constitution of the image forming device can be simplified, and a cost can be reduced.
