Title: Opening and shutting mechanism of door body
Inventor: KONDO HIROSHI
IPC: H02B1/40
Filed: 1994-05-17
Abstract: PURPOSE:To obtain an opening and shutting mechanism which couples a locking piece to a box body by the biasing force of a spring and which makes the opening and shutting operation of a door body easy by a method wherein an arm body at one end of the spring installed at a hinge part is coupled to a door-body biasing piece and the other end is coupled to a handle-biasing piece and installed in a handle mounting hole so as to be rotatable. CONSTITUTION:When a door body 1 is to be opened, a handle 3 is held and the door body 1 is pulled to an opening direction. Then, the handle 3 is turned to the direction of A by making use of a hinge part 4 as an axis, a locking piece 6 is detached from a coupling opening part 8a in a box body 8, a rotation control piece 9 is coupled to the inside end edge part of the door body 1 faced with a door-body biasing piece 2, and the door body 1 is opened. In addition, when the door body 1 is to be shut, it is pressed to the side of the box body 8. Then, an inclination part 6a at the locking piece 6 is slid to the end edge part of the box body 8, and the handle 3 is turned to the direction of A by making use of the hinge part 4 as an axis. However, when the door body is shut, the locking piece 6 is coupled to the coupling opening part 8a in the box body 8 due to the biasing force in the direction of B of a coil spring 7 installed at the hinge part 4. As a result, the opening and shutting operation of the door body can be performed serially and very easily.

Title: Recording state detector for track of magnetic disk
Inventor: WAKUI YOSHIO
IPC: G11B27/10
Filed: 1990-05-17
Abstract: PURPOSE:To accurately detect the recording state of a track in spite of the position of the track by comparing a signal to be decided outputted by reproducing the track with a prescribed reference value, and deciding whether or not the track is already recorded. CONSTITUTION:A track position detecting means 1 detects the track position of a magnetic disk D, and a reference value setting means 2 sets a small reference value, smaller toward the further inner peripheral side of the magnetic disk D the position of the track is located at. Also, an output means 3 for signal to be decided outputs the signal to be decided by reproducing the track, and a decision means 4 decides whether or not the track is already recorded by comparing the signal to be decided with the reference value. By employing such constitution, it is possible to accurately detect the recording state of the track in spite of the track position, and to prevent the presence/absence of records on the tracks at the inner and outer peripheral sides of the magnetic disk D from being judged erroneously.

Title: Transmission right management system of ring network
Inventor: YAMAGA MITSUHIRO
IPC: H04L12/433
Filed: 1984-06-22
Abstract: PURPOSE:To avoid the competition in plural nodes by allowing each node to generate a time-out value of a transmission right supervisory timer detecting missing of each token based on the own node address on a ring network. CONSTITUTION:Equipments 16, 17-21 having a processing function are connected respectively to nodes 10, 11-15 in a ring circuit network having a node addressed to the nodes 10, 11-15. Suppose that the node 15 transmits a token on a ring and the token is missing between the nodes 12 and 13, the node 13 detects the time-out of transmission right earlier by a prescribed time T0 than by the node 14, constitutes the token and transmits the result to a ring circuit network. in deciding largely the T0 than the time required for restoration of the transmission right of the node, it is avoided that the node 14 detects the timeout of transmission right.

Title: Spectrum detector
Inventor: MORISANE SHIZUO
IPC: G01J3/18
Filed: 1985-06-12
Abstract: PURPOSE:To reduce the size of a sensor and to simplify a measuring system by integrating a diffraction grating and an analyzing functional element of the quantity of light on a substrate for ICs. CONSTITUTION:The diffraction grating 3 which has plural parallel slits 2 and is formed in a line is packaged at the equal intervals on the surface 1a of the substrate 1 for the ICs and the phototransistors 4 are integrated as the analyzing functional element of the quantity of light and fitted to the lower part of the intervals of the diffraction grating 3. The diffraction grating 3 sets a main lobe value of the transmitted waves from the slits 2 according to the frequency of the incident waves from a vertical direction by such constitution. Accordingly, the frequency can be detected by the voltage generating from the phototransistors 4 by the frequency of the incident waves. Hereby, the size of the sensor is reduced and the measuring system can be simplified.

Title: Production of torus by electron beam welding
Inventor: MATSUNAGA TSUNEFUMI
IPC: B23K15/00
Filed: 1982-07-23
Abstract: PURPOSE:To prevent the melting of non-weld zone, by subjecting a torus to be welded to electron beam welding after packing a shielding material for an electron beam therein thereby shielding the penetration of the electron beam. CONSTITUTION:The inside circumferential edge of the outside ring member 2 of a torus and the outside edge part of the inside ring member thereof are butted to each other. A shielding material 7 for an electron beam in a powder, granular or fibrous form is packed through a drilled part 6 into the torus. The above- described butt parts 4, 4' are welded by an electron beam. The material 7 is discahrged through the part 6 to the outside, whereafter the part 6 is sealed. The melting of non-welded parts by the electron beam penetrating through the weld zone is thus prevented and the torus is easily produced.

Title: Protection circuit against surge voltage
Inventor: TERAGAKI MASARU
IPC: H05K1/11
Filed: 1990-05-17
Abstract: PURPOSE:To reduce cost with a power source device miniaturized and the need for a protecting member such as a surge killer eliminated by forming discharge gaps between the input and the output sides of a line filter with patterns of printed boards. CONSTITUTION:Discharging gaps 22 and 23 are formed between the input and the output sides of a line filter 4 with patterns 18-21 of printed boards. When surge voltage is applied between input terminals 14 and 15 and ground, back electromotive voltage is generated in a line filter 4, but it is discharged when reaches discharge voltage, and only voltage, in which the discharge voltage in the line filter 4 is added to applied surge voltage, is generated between a rectification smoothing circuit and the ground. Consequently a creeping distance between the rectification smoothing circuit and the ground can be shortened compared with a case when a discharge gap is unprovided. This can minimize a power source device and eliminate the need for a protecting member such as a surge killer, and thereby reduce cost.

Title: Treatment of waste water
Inventor: SANTO YOSHITERU
IPC: C02F1/58
Filed: 1990-05-17
Abstract: PURPOSE:To perfectly separate polyvinyl alcohol and moisture by adding peroxosulfate to waste water and heating the waste water to obtain water free from polyvinyl alcohol. CONSTITUTION:The waste water received in a receiving tank 1 is heated in the presence of peroxosulfate and PVA in the waste water is separated. The water free from PVA is temporarily stored in a neutralizing tank 6 to receive the addition of a neutralizing agent and the neutralization of PVA, that is, the generation of sulfate is suppressed. The water free from PVA neutralized in the neutralizing tank 6 enters a separator 7 to separate PVA and moisture. Since separated PVA is dehydrated until the water content thereof becomes about 60-70%, PVA can easily be dried by the next dryer 8. A part of dried PVA is used as fuel and the remainder thereof is carbonized to be capable of being used, for example, as activated carbon for decoloring waste dyeing water or absorbing oil.

Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To actualize a method and a device which provides a high-precision resolution without requiring a large amount corpuses and which performs high- precision cost determination without manual intervention. SOLUTION: A morpheme analysis of an input sentence is performed (step S1). Word divisions of the morpheme analysis result are compared with word divisions of the correct answer of a previously provided corpus (step S3), and when they do not match each other, a sample is generated which shows differences between the feature vectors of the morpheme analysis result and the feature vectors of the corpus (step S5). As for samples which are generated so far, the value of a weighted vector is calculated from the value of the reverse matrix of the variance/covariance matrix of the sample and the mean transposed matrix of the sample (step S6).
