Title: Line wire hooking system
Inventor: FURUI KATSUNORI
IPC: H04Q3/58
Filed: 1990-10-22
Abstract: PURPOSE:To prevent a server from being puzzled by automatically sending a hooking signal to a counter station through a trunk circuit at the time of hooking operation due to the extension server who is speaking with the counter station, which can detect the hooking signal, through a line wire and eliminating a need to give a difference of hooking operation between speaking in the local station and speaking to the line wire by the server. CONSTITUTION:When the server of an extension telephone set 6 performs the hooking operation, a central controller 2 reads out contents of a main storage device 3 to discriminate whether the telephone set is in the speaking state to the counter station or not. Then, the controller 2 transmits a command, which sends the hooking signal to the counter station, to a trunk circuit 5 with a time division switch 1 closed. When receiving this hooking signal sending command from the controller 2, the circuit 5 sends the hooking signal to the stored counter station through a speech line. When receiving the signal, the counter station sends a second dial tone for the purpose of performing confirmation. Consequently, the server of the telephone set 6 hears the second dial tone through the circuit 5 and the switch 1.

Title: Picture density adjusting device
Inventor: FUJISAWA SHUJI
IPC: G03G15/08
Filed: 1986-11-27
Abstract: PURPOSE:To always obtain the perfectly adjusted density of a copying machine, by controlling the density of an image corresponding to an original image so as to coincide exactly with that of a toner image transferred on a copying sheet actually. CONSTITUTION:In the copying machine, the picture density of an original is detected by performing the exposure scan of the original by a light source, and passing the beam of light having intensity corresponding to the variable density of the original image through a picture density detecting sensor 7. Also, an electrostatic latent image corresponding to the original image is formed on the surface of a photosensitive body by the beam of light passing the picture density detecting sensor 7, and toner is attached on the image at a developing part, then, the toner image can be formed. The picture density of an obtained toner image is detected with a toner density sensor 11. Thus, the picture density based on the intensity of the beam of light on the same part of the image and a toner density signal based on the attached quantity (variable density) of the toner can be obtained, and they are compared, then, a toner density adjusting means such as a toner refilling motor 16, etc., is driven so as to reduce a difference between them, and thereby, correspondence relation between the picture density and the toner density can be maintained constant invariably. In such way, it is possible to adjust the density of the toner image exactly.

Title: Identification and discrimination device for paper money
Inventor: KITAMURA AKIRA
IPC: G07D7/00
Filed: 1990-10-22
Abstract: PURPOSE:To reduce the amount identification information and to shorten time required for discrimination by detecting positive or negative polarity at each reading point, comparing the inverted point with the information in a ROM and discriminating the kind of the paper money and truth from falsehood. CONSTITUTION:The identification data stored in a ROM 11 is the data indicating the position of an inflection point at each pattern reading point on the paper money. A CPU 12 discriminates the kind of the bill and truth from falsehood by comparing the inflection point at each reading point of the data concerning the pattern of the read paper money instead of recognizing the pattern on the surface of the paper money as values of varying density. Thus, troubles of increasing the amount of information and lengthening the discriminating time can be eliminated.

Title: Method for joining slab
Inventor: ISOYAMA SHIGERU
IPC: H05B6/10
Filed: 1994-11-18
Abstract: PURPOSE: To join to tip parts in the width direction of slabs without possibility of erosion by joining the center areas in the plate width direction of the tip parts of the slabs, pressing while heating them again by an induction heating coil, and joining unjoining areas of both tip parts in the plate width direction. CONSTITUTION: After a primary upset, when energizing a coil again, since the center area is joined but an end part does not come into contact, an induced current generating by an alternating magnetic field becomes an ambient current. Moreover, in this case, since the current is concentrated at the width end part of an unjoining part, a heating-up in this part is quick. When restarting depression in this state, the end part whose temperature is raised and the unjoined part are joined. Consequently, the slab can be perfectly joined all over the areas in the width direction without possibility of erosion caused by a spark, and stable connecting hot rolling can be realized.
