Title: Air filter
Inventor: KUROKAWA KEIKO
IPC: B01D39/14
Filed: 1989-03-17
Abstract: PURPOSE:To obtain stabilized antibacterial effect and physical resin properties of the air filter without causing a reaction between chemicals by adding antibacterial agents of different kinds to the respective fibers, weaving the fibers into a net and further forming the air filter from the net. CONSTITUTION:The yarn A added with a chemical (a) and the yarn B added with a chemical (b) are woven with the yarn A and the yarn B alternately as the warp and weft to form a net 1, and an air filter of specified shape is formed from the net 1. Two kinds among diphenyl ether, N-haloalkyl thio compds. and benzimidazole are used as the antibacterial agents to be used as the chemicals (a) and (b). Consequently, a reaction between the chemicals is not caused even when the antibacterial agents having a complementarity antibacterial spectrum are used. Accordingly, a filter having stabilized antibacterial effect and physical resin properties is obtained.

Title: Production of oxide-based superconducting material
Inventor: SUGIMOTO MASARU
IPC: C01G1/00
Filed: 1988-03-18
Abstract: PURPOSE:To obtain the title material with oxide superconducting layer of dense structure formed, by forming an oxide layer of specific composition ratio externally on a metallic core followed by further forming a Cu-A alloy layer externally on said oxide layer in succession to produce a composite material which is then heat treated to effect mutual diffusion of the respective elements in said oxide layer and alloy layer. CONSTITUTION:Respective elements in a Cu-A alloy layer formed externally on a metallic core and the elements in an oxide layer of a composition A1B2Cu1 O5 are allowed to mutually diffuse by heating treatment at 800-1,300 deg.C for several hours to several hundred hours, thereby forming an oxide superconducting layer of a composition A1B1Cu3O7-delta (see, the formula). The melting point of the Cu-A alloy layer is lowered due to the addition of the A-element to effect melt diffusion-and-reaction with the elements in the oxide layer by heating in said heat treatment, thus forming the oxide superconducting layer. This melt diffusion-and-reaction causes a uniform reaction of high reaction rate, resulting in the formation of an oxide superconductor of dense structure.

Title: Semiconductor device
Inventor: HIROKI MASANORI
IPC: H01L21/31
Filed: 1983-04-15
Abstract: PURPOSE:To facilitate the etching of connection holes and form them properly, and thus perform good connection by a method wherein all the insulation films on a conductor layer of multilayers and a diffused layer are formed to the same film thickness. CONSTITUTION:A conductive poly Si pattern 13 is selectively formed on an Si substrate 10 provided with a field oxide film 11 and a gate oxide film 12. Next, when SiO2's 14 and 15 are formed on the main surface of the substrate 10 and the first conductor layer 3, the film 15 is formed thickly and the film 14 thinly. Then, the second poly Si pattern 16 is selectively formed, and an ion implanted layer 17 is formed with the layers 13 and 16 as a mask. The layer 16 also turns a conductor layer at this time. When thermal oxide films 18 and 19 are grown thereafter, the growth is fast in the conductor layer 16 and the ion implanted layer 17 by impurity introduction, and accordingly said films become thick. Suitable determination of the condition of oxidation enables to make the thicknesses of the SiO2 films 18 and 19 nearly equal to that of the SiO2 film, and at the same time the source and drain 20 are formed by the diffusion from the layer 17. Then, when wirings 23 are laid by covering with a PSG21 and opening windows 22, contact failure and the short-circuit between the substrate do not generate, thus enabling good connection.

Filed: 1978-05-31
Abstract: PURPOSE:To use the operation display element also for the overcurrent display purpose for the contactless switch containing the circuit part including the output switching element which turns on and off according to the detection and non- detection active states of the substance plus the display element which turns on and off according to the above mentioned active states. CONSTITUTION:The time constant circuit consisting of capacitor 43 and resistance 42 connected between the power lines is installed along with timer circuit 41 which generates the output until the overlap voltage of capacitor 43 reaches the fixed value plus overcurrent detection circuit 51 which detects the current flowing to output switching element 61 exceeds the fixed value and then discharges capacitor 43 in circuit 41. Thus the output of circuit 41 is used as the control signal which turns off the switching output and also turns on display element 34. As a result, the output switching element can be protected from the overcurrent, and at the same time the display element for operation display can be used also for diaplay of the overcurrent.

Title: Paper drive control method in laser beam printer
Inventor: TSUCHIYA KIYOMI
IPC: B65H23/188
Filed: 1988-03-18
Abstract: PURPOSE:To prevent characters from becoming bold to excessive paper fixing at the start or stop of printing action by determining a paper stop position at the end of printing action in a contact part between a heat roll and a pressure roll as a printing inhibited area. CONSTITUTION:A rotation signal HR ROT-P for a heat roll 7 is turned OFF at the position of a perforation line 2 with an elapsed time T3 from a point A at which a printing action stop signal is received from a host device. In this state a paper feed action is conducted, and after the completion of the action a paper is fed back by the amount of (T1-T3)+T2 to be prevented from paper slackening on a buffer. At the start of the second printing or thereafter, the shift of the printing start position is prevented by issuing HR ROT-P and PAPER FEED-P signals after the reception of a printing start signal CPF-N at a timing of (T1-T3). In this manner, a contact part between the heat roll 7 and a pressure roll 8 is determined as a printing inhibited area 12 without affecting printing data, and characters can be prevented from becoming bold due to the excessive fixing at the contact part.
