Title: No-voltage tap-changer
Inventor: ANAHARA KINJI
IPC: H01F29/02
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a plurality of no-voltage tap-changers in a transformer to obtain four levels of voltage, with one tap doubling prescribed voltages of the transformer. SOLUTION: Changing sections of this no-voltage tap-changer are composed of three blocks TC1, TC2, TC3 and are mounted on a gear case 30. Each changing section has drive axes A-H at its center and fixing axes having fixing contacts 1-28, attached thereon in its outer periphery. Through the operation of an operation handle 31, rotation operation is transmitted to the drive axes via a Geneva guide 34 and a Geneva gear 33 (only TC1 is further provided with a spur gear) mounted in a gear case and movable contacts mounted on the drive axes connect or separate the fixed contacts with each other. Consequently, coil parts are connected in series or in parallel, and thereby four levels of voltage, each tap doubling the other, can be obtained.

Filed: 1993-03-31
Abstract: PURPOSE:To facilitate the connection and the drawing work of electric wires, and to recognize the secure connection by providing a cancelling member, a locking member and an inspecting member besides an operating member. CONSTITUTION:When an operating member 4 is operated from outside of a terminal main body 1, a cancelling member 5, which is pushed by the operating member 4, pushes a locking spring 2 to the canceling direction, and the operating member 4 is locked by the locking member 40 under the condition that the locking spring 2 is cancelled.

Title: Radiation linear pulse transmitter
Inventor: ISHII KAZUHIKO
IPC: H04B10/00
Filed: 1984-04-16
Abstract: PURPOSE:To compensate the change of an analog level due to the variation of characteristics of an optical fiber cable, etc., and to measure exactly linear pulse by superposing a DC signal onto a signal transmitted via an optical transmission system and setting the threshold value of a received signal at the reception side with the voltage proportional to the level of said superposed signal. CONSTITUTION:An addition signal (S1+S2) of a radiation linear pulse signal S1 to be measured and a DC component signal S2 is supplied to an attenuator 61. The output X2 of the attenuator 61 is shown by an equation I , where the attenuation factor is referred to as alpha. A discriminator 62 isolates a DC component aS2 and a linear pulse component aS1 out of the signal X2 as shown by equations II and III. A threshold value control circuit 63 has the set value beta for correction of various types of noise components, and an equation IV shows the relation between an input X4 and an output V1. A comparator 64 obtains a ratio between X3 and V1 to satisfy X5=X3/V1=S1/betaS2 for an output X5. Thus the output X5 contains no component (a). In other words, the output X5 of the comparator 64 is not affected an attenuation factor (a) obtained by the characteristic variation.

Title: Gloss control method for electrography device
Inventor: GOETHEM LUC VAN
IPC: G03G15/20
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain excellent quality of fusion and expected gloss without executing an intermediate fusion, by selecting the rotary speed for a fusing device roller based on the expected gloss on the selected temp. depending on the case. SOLUTION: The gloss of the image depends on the fusion time, namely, fusion speed and contact length, fusion temp., and quantity of oil. The time for fusing device rollers 60 and 62 to come into contact with toner particles on a sheet 54, depends on the speed of the sheet 54 with respect to a nip 61 and the length of the nip 61, rather than the fusing time. The fusion temp. depends on the heat capacity and thermal conductivity, and the thermal conductivity from the roller surface to the image receiving sheet. By applying the normal control or the fuzzy inference control, considering the glossiness grade, the quality of paper to be selected and the numbers of prints to be produced, and combining the fusing temp. and the fusing speed, the most effective result can be obtained.  In this way, when the fusing temp. falls, as a result of the extreme heat loss, by making the speed of the fusing roller adapted for every page, the uniform glossiness can be realized.
