Title: Mechanism and method for inspecting pin breakage of dot printing head
Inventor: SATO YUICHIRO
IPC: B41J29/46
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To check pin breakage of a dot printer by detecting the continuity of the pins of a printing head and a check platen. SOLUTION: Potential of +5(v) is applied to a printing head and a check platen 3 outside the printing area of a platen 2 is earthed to the ground. The printing head 1 is moved to the region above the check platen 3 to allow pins to impact against the platen 3 one by one. If the pins are not broken, the potential of the printing head 1 lowers to 0(v) and, if the pins are broken, the potential of the printing head 1 is held to +5(v) as it is. The signal due to the potential of the printing head 1 is connected to a counter 4 and, if pulses corresponding to the number of pins are confirmed, a normal signal is outputted to a control part 5 and, if pulses corresponding to the number of pins or less are confirmed, an inferior signal is outputted thereto.

Title: Clamping tool
Inventor: MORITA TAMAO
IPC: H01F7/02
Filed: 1986-12-26
Abstract: PURPOSE:To eliminate the decrease of an attracting force due to the generation of a gap between a ferromagnetic plate and a permanent magnet by using a magnet molded by synthetic resin containing hard magnetic powder, and bonding a plate to the magnet with an adhesive, thereby a case for protecting the magnet. CONSTITUTION:A ferromagnetic plate 2 is attached to one pole face (a) of a permanent magnet 1 having a hole 1a directed from the pole face (a) to the other pole face (b) so that ferromagnetic protrusions 3a, 2a projected from both or one of a ferromagnetic plate 3 and the plate 2 contacted with the pole face (b) are detachably attracted through a hole 1a to the plate 2 or 3. In such a clamping tool, the magnet 1 is molded with synthetic resin containing hard magnetic powder, and the plate 2 is bonded with an adhesive to the magnet 1. Thus, a case for protecting the magnet can be omitted. A gap between the plate 2 and the magnet 1 is reduced to decrease a magnetic resistance, and the increase of the gap during its use can be eliminated.

Title: Method for deciding and adapting block size used for audio conversion coding
Inventor: SHEN MEI SHEN
IPC: G10L19/02
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To control a signal with a limited bandwidth by deciding the number of windows based on a block size effective to a conversion coder, sampling an input audio signal at a time interval, grouping sampled signals, and generating a comparison index and selecting a proper block size or window. SOLUTION: A frame of each subband is divided into sub frames. A current frame of a subband has extended parts of 16 samples to detect an attack signal. Furthermore, the difference between adjacent peak levels is checked, and if the difference between the adjacent peak levels is smaller than a prescribed threshold, the difference between adjacent peak levels apart by a segment of the sub frame is detected. After the numbers of subbands and frame sizes are initialized, a block size is decided for each of respective subbands. The frame of each subband is extended with a window function of an adaptive block size by considering all the included samples.

Title: Cutting tool
Inventor: KONO YUICHIRO
IPC: B23B27/18
Filed: 1989-11-27
Abstract: PURPOSE:To make the size of a rigid sintered body small by forming a seat surface of a recess part on the main body side where the bottom surface of the sintered body is to be attached to protrude having a level difference along the feed direction of a tool toward a rake face of the tool. CONSTITUTION:A small rigid sintered body consisting of a rigid sintered body 1 and a base 2 fixed to it is installed to a recess part 6 provided to be suitable to the corner part of a tool main body 5 by brazing a bottom surface 3 with a back surface 4. The seat surface of the recess part 6, that is the surface where the bottom surface 4 is to be attached, is of an inverse V-letter shape formed of two planes crossing with each other at the center by an angle of theta. For cutting a quenched blade, among a main component force Fc, a feed component force Ft, and a back component force Fo, the back component force Fo is the biggest, and the feed component force Ft is the smallest for the main component force Fc. In this case, the main component force Fc pushes the sintered body 1 which floats to the rake face side back to the seat surface side by the feed component force Ft. Fc is generally larger than Ft, so a necessity to be durable to the feed component force by the attachment force is almost eliminated, and the durability to the feed component force is very strong.

Title: Simple accessory device for polarization observation for ophthalmology
Inventor: YANO NOBUYUKI
IPC: A61B3/12
Filed: 1989-11-28
Abstract: PURPOSE:To facilitate observation of an eye to be examined in a direction of polarization at an optional angle by making a lighting system to illuminance with a light polarized linearly turn together with an observation system comprising a polarization filter with a polarization axis orthogonal thereto. CONSTITUTION:A light source 3 is turned ON to light a front eye of a person to be examined. Natural light leaving a lamp 3 passes through a collimator lens 5 after passing through an aperture 4 to make a parallel luminous flux. Thereafter, with the passage through a filter 6, the light with an undesired wavelength is cut and the light passing through a polarization filter 7 makes a linearly polarized light polarized to a direction vertical to the paper. As characteristics of a polarized beam splitter 8 is that S components of light are reflected mostly while P components thereof are transmitted mostly, the linearly polarized light is reflected with the polarized beam splitter 8 with little loss to light an eye 9 to be examined. The light reflected at parts of the eye 9 to be examined reverses an optical axis 12 of an observation system and passes through the polarized beam splitter 8. It is only the light polarized parallel with the paper that can be transmitted through the polarized beam splitter 8 and a polarization filter 10. To rotate a polarizing plane, a lighting lens barrel 1 is turned.

CONSTITUTION:Nucleus formation regions 1 in which a nucleus it easy to form are arranged periodically in such a way that their circumferences are surrounded by a region 2, not forming a nucleus, in which the nucleus is hard to form; single crystal nuclei 3 are formed selectively in the nucleus formation regions. That is to say, impurity elements by which thin films forming the regions 1, 2 having a different state inside a face display a speed-increasing effect are contained in the films; and they are annealed at the temperature of a melting point or lower. The single crystal nuclei 3 are formed preferentially only in specific positions inside the face and are grown to the transverse direction up to the circumference. Thereby, it is possible to obtain a thin-film crystal composed of a group of crystal particles, of a large particle size, in which grain boundary positions between adjacent crystal particles and particle sizes have been controlled.
