Title: Thin current fuse
Inventor: TAKEGAWA HIROAKI
IPC: H01H85/175
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a thin current fuse which can shut off current safely, without melting the resin base film when overcurrent doesn't exceeds two times the rated current. SOLUTION: In this current fuse where a pair of electrodes 21, 21 are mounted on a resin base film 11. A current fuse element 3 is connected between the electrodes 21, 21. The resin base film is sealed by a case-like resin cover film, gap is arranged between the current fuse element 3 and the resin base film 11. Accordingly, even overcurrent not exceeding two times the rated current can be shut off in its flow safely certainly, and the thin current fuse can be mounted to a lithium ion secondary battery to thereby prevent an accident caused by the overcurrent due to internal short-circuiting.

Title: Device for scanning beam in two directions
Inventor: IKURUMI KAZUHIRO
IPC: G02B26/10
Filed: 1990-11-07
Abstract: PURPOSE:To realize a device for scanning a beam in simple constitution at high speed by attaching vibration bodies having different characteristic frequency and vibration direction to the vibration part of a vibration source and scanning a beam in a plurality of directions by means of the reflecting mirror attached to a vibration body. CONSTITUTION:A vibration source 5 is vibrated to vibrate vibration bodies 1 and 3. Since a reflection mirror 4 is attached so as to vibrate in the different direction which the two vibration bodies 1 and 3 have, it is vibrated in two directions. In the next step, when incident light 13 is radiated to the reflecting mirror 4, the reflected light from the reflecting mirror is scanned in the lateral direction due to the vibration of the characteristic frequency of the vibration body 1 and in the longitudinal direction due to the vibration of the characteristic frequency of the vibration body 2. By such simple constitution, a device for scanning a beam in two directions at high speed can be realized.

IPC: G03G21/16
Filed: 1993-12-03
Abstract: PURPOSE:To reduce the number of processes for a work to install a guide member on a belt-shaped photoreceptor to facilitate the work by bringing a guide member in contact with the side of a restriction member which is installed on the side of one or more rollers or their roller shafts positioned at the outside of the belt-shaped photoreceptor to restrict deviation. CONSTITUTION:A guide member 15 is provided on the outer surface of a belt- shaped photoreceptor 1, and restricted by the side of a charged roller 6. It is also restricted by a restriction member 16 installed on a roller shaft 17. In this case, because the charged roller 6 runs slightly into the belt-shaped photoreceptor 1, a distance 11 between the surface of the belt-shaped photoreceptor 1 and the center line of the roller shaft 17 is related with the radius (r) of the restriction member 16 as (r)<=11 and a distance between it and the center line of the roller shaft 17 near the end of the belt-shaped photoreceptor 1 is taken as 12. Thus, the work can be facilitated by reducing the number of processes for a work to install the guide member 15 on the belt-shaped photoreceptor 1.

Title: Sputtering target for producing integrated circuit device
Inventor: MAEDA AKIYOSHI
IPC: H01L21/285
Filed: 1989-11-21
Abstract: PURPOSE:To form a film having a fixed composition regardless of the consumption of a target by increasing the rate of an element having a smaller mass in the composition distribution of the elements of an alloy target in its depth direction as the depth from the surface increases. CONSTITUTION:In the sputtering target for producing an integrated circuit device consisting of an alloy, the rate of the element having a smaller mass number is increased as the depth from the working surface of the target increases. The composition distribution of the elements is thus formed. When the target is sputtered, the atom of the component element having a smaller mass number in the region distant from the working surface is susceptible to scattering as the sputtering proceeds, and the rate in the film forming composition is decreased. The rate of the small-mass element in the region distant from the working surface is previously increased in this target to compensate the decrease. Consequently, a film having an almost same. composition is formed regardless of the consumption of the target.

Filed: 1990-11-13
Abstract: PURPOSE:To enable operation without errors clearly distinguishing a laser light for treatment from a collimation light by providing a box section with a detection means for detecting a foot of an operator to irradiate the collimation light by a signal from the detection means. CONSTITUTION:A box section 20 is provided with a detection means 22 to detect a foot 25 of an operator therewith 22. When the operator inserts the foot 25 into the box section 20, with the insertion thereof, a signal S1 from a photo detecting section 24 is sent to an AND circuit 26 and a laser device 12. The laser device 12 outputs a collimation light L2 by the signal S1. The collimation light L2 irradiates a part 80 to be treated through an optical fiber 3. Then, as the operator steps on a foot switch 21 by the foot 25, a signal S2 is sent to the AND circuit 26. Thus, the AND circuit 26 outputs a signal S3 to be applied to a control section 13. The control section 13 drives a ruby laser device 11 to irradiate the part 80 to be treated with an intense laser treating light L1 through the optical fiber 3.

Abstract: PURPOSE:To obtain a ceramic resistor having excellent AC strength by forming a high resistance layer on the side face of a sintered material containing zinc oxide as a main ingredient, forming electrodes on both upper and lower end faces of the material, and incorporating silicon.zinc in the side face high resistance layer to specify its average composition. CONSTITUTION:The side face of a sintered material 1 is coated with paste mixed with SiO2 powder together with organic binder, dried, and seized at a high temperature to form a side face high resistance layer 3 containing SiO2. The composition of the layer 3 contains 5-70mol% of Si in terms of SiO2, 25-90mol% of Zn in terms of ZnO and zero to small amounts of Al2O3, MgO, ZrO2, TiO2, Sb2O3 and Y2O3 by averaging the quantities to the position of 200mum of depth from its surface at the side face of the material 1. The SiO2 is reacted with the ZnO of the material 1 or the ZnO in the paste to form Zn2SiO4. Thus, since the Zn2SiO4 becomes the layer 3 and the SiO2 fills pores in the material 1, discharge on the surfaces of the pores is prevented, and AC strength is improved.
