Title: Write circuit for magnetic disk device
Inventor: HASHIMOTO TOSHIKAZU
IPC: G11B5/09
Filed: 1988-07-13
Abstract: PURPOSE:To prevent occurrence of a state where readout of desired data information is disabled due to a wrong positioning operation by not performing the inversion of the magnetization of a magnetic head for writing when the pulse interval of write data is within a prescribed period. CONSTITUTION:When a write signal 15 becomes 'L', magnetizing currents 16 and 17 are produced. When the pulse of a write data signal 10 arrived thereafter, the currents 16 and 17 are inverted and, accordingly, the magnetized direction of a recorded magnetized pattern is inverted. However, when the pulse of the signal 10 arriving within a prescribed period beyond the time specified by a triggerable one-shot circuit 2 is inputted, the pulse is not inputted to an FF 4 for writing by means of an AND gate 1. Therefore, the currents 16 and 17 are not inverted.

Title: Surface treating apparatus
Inventor: NINOMIYA TAKESHI
IPC: G03F1/00
Filed: 1982-10-08
Abstract: PURPOSE:To obtain a surface treating apparatus having a high machining speed, by combining laser light with the surface treating apparatus, wherein an ion microbeam is used. CONSTITUTION:On a sample 4, which is placed in a chamber 3, an ion beam from an ion source 1 is accelerated, converged, and projected. At the same time, laser light from a laser light source 7 is projected through a window 5. At this time, the laser light can be converged by using a lens group 6 as required. The laser light can be projected at the same time with the ion beam, or the ion beam can be separately projected to the sample 4, after the laser light is projected. When etching is performed, e.g., visual, ultraviolet laser light is used. When the ion beam is projected, with energy that is required for dissociating atmos and molecules constituting the sample 4 being supplied by the laser light, the etching speed is increased in comparison with the case where the laser light is not used together.

Title: Data-recording material
Inventor: TAGIWA IZUMI
IPC: B41M5/36
Filed: 1987-07-15
Abstract: PURPOSE:To make it possible to record images with high contrast and enable favorable recording with low thermal energy, by providing a reversible recording layer being in a transparent state or a milky white state and capable of transition from one of the two states to the other when being heated, and a base member having a metallic luster and supporting the recording layer. CONSTITUTION:A reversible recording layer R is formed in a thin film shape from a recording material, is in a transparent state or a milky white state at normal temperature, and is capable of transition from one of the two states to the other when being heated. The reversible recording layer R is provided on a base member 10, which has a metallic luster. When this information- recording material is irradiated with light from the face side, the light is reflected by the base member having the metallic luster, in transparent areas of the recording layer R. On the other hand, in milky white areas of the recording layer R, not only the light is reflected diffusedly but also the light transmitted through the layer R while being diffused is reflected by the base member 10 and then again diffused in the milky white areas. Thus, the whiteness degree of the milky white areas is further enhanced, resulting in a higher contrast of images being displayed.

Abstract: PROBLEM TO BE SOLVED: To enable responding to heterogeneity of assembly without increasing calculation time too much by obtaining neutron current response from boundary to boundary of assembly calculation region in the step of assembly calculation in 2 step calculation and using it as a nuclear characteristic value of assembly instead of nuclear constant in core calculation. SOLUTION: In plane method, eigen value calculation is performed by assuming infinite arrangement of an assembly and infinity in vertical direction, and information obtained about partial neutron current in each region boundary is stored. Simultaneously, nuclear constant of regional average is calculated and stored. Then, the partial neutron current preserved in a regional plane is set as an inflow current and fixed source calculation is performed with another plane as a vacuum boundary condition to calculate the outflow current from each regional plane. After repeating this for each regional plane, the ratio of outflow current amount to inflow current amount is calculated to be current response. According to the current response, neutron current distribution in the core and reactivity are calculated.
