Title: Multiplier
Inventor: MATSUBARA TATSUO
IPC: H03K5/00
Filed: 1988-11-29
Abstract: PURPOSE:To obtain a multiplied waveform with less jitter and excellent accuracy by forming the multiplier with two comparator circuits and differentiating circuits. CONSTITUTION:An input signal 11 is given to a comparator 1, and a level over +V is outputted as an output wave 12, and a level below -V is outputted from a comparator 2 as an output wave 13. An OR circuit 3 outputs OR between the output waves 12,13 and a double wave 14 is obtained. The double wave 14 appears as an output wave 16 for a time constant  t of a differentiation circuit 5 only and an output wave 15 inverted by an inversion circuit 4 appears an output wave 17 only for a time constant  t of a differentiation circuit 6. An OR 7 outputs an OR of the output waves 16,17, and a four multiple wave 18 is obtained. Thus, an output waveform with high accuracy and less jitter is obtained.

Title: Conveying device
Inventor: MORI MASATO
IPC: B65G54/02
Filed: 1989-11-24
Abstract: PURPOSE:To ride on or alight from carriers without stopping a conveying path and allow high-speed mass transportation in a short time by providing carriers running on the conveying path and riding/alighting paths moved at a speed lower than that of carriers in the same direction as the conveying path along it. CONSTITUTION:A carrier 1 is run on a conveying path 2 without stopping, when it reaches a riding path, a riding door 11 is opened. Passengers first ride on a low-speed riding path 32, then move to an intermediate-speed riding path 31 and reach a high-speed riding path 3. Passengers are moving in parallel with the carrier 1 at a speed slightly slower than that of the carrier 1 and easily can ride on the carrier 1 through the riding door 11. When the carrier 1 has passed the high-speed riding path 3, the riding door 11 is closed. People unable to ride on the carrier 1 move back and escape toward the low-speed riding path 32 and can prepare for the next riding. When the carrier 1 with passengers reach an alighting path, an alighting door 12 is opened, passengers move from a high-speed alighting path 4 to a low-speed alighting path 42 in the opposite order to riding, finally they move to the stationary floor.

Title: Multilayer printed wiring board and method of production
Inventor: KAWASAKI YOGO
IPC: H05K3/46
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a multilayer printed wiring board, and a method of production, having a high reliability of connection in which the internal length of wiring can be shortened. SOLUTION: Through holes 36 are made through a core board 30 and a lower interlayer resin insulation layer 50 and via holes 66 are made immediately above the through holes 36. Since the through hole 36 and the via hole 66 are straight, the wiring length is shortened and the transmission rate of signal can be increased. Furthermore, connection reliability is enhanced because the through hole 36 is connected directly with the via hole 66 being connected with a solder bump 76 (conductive connection pin 78).

Abstract: PURPOSE:To make an electronic apparatus to fully exert its handy feature when the apparatus is applied to a small-size handy terminal, etc., by providing a controlling means which finds the consumed quantity of a battery based on the count value of the operating hours of the battery after the use of the battery is started. CONSTITUTION:At the time when an old battery is exchanged with a new battery 5, a consumed quantity integrating counter in a control CPU 1 is cleared. When the operation of the apparatus using the battery is started thereafter, the kind N of the operation mode is discriminated and the weighting quantity W corresponding to the kind N of the operation mode is read out from a data table in a memory 2 and a preparatory work is performed. During the operating state waiting for a key input, the consumed quantity of the battery 5 is counted by adding five counts each at every unit operating time. The calculation of the consumed quantity of the battery 5 is continued until the battery 5 is exchanged with another new battery and the integrated consumed quantity is saved in the memory 2. The integrated consumed quantity is displayed on an LCD 3 through a keyboard 4 when it is required, and thus, the consumed state of the battery 5 can be detected.

Abstract: PURPOSE: To maintain highly efficient battery characteristics and reduce non-reacted raw material compounds by composing a layer structure by a heat reaction of a transition metal compound with an excessive amount of a molten lithium salt as a raw material for compounding which is directly involved in the reaction. CONSTITUTION: As raw materials for compounding, cobalt oxide powder and lithium carbonate powder are mixed mutually in a ratio; 1.0 mole of cobalt oxide to 2.0 mole, which is excessive, of lithium carbonate; and these two oxides are stirred. In molten salts of the raw materials for compounding, a powder mixture of the lithium compound and the transition metal compound as raw materials for compounding is melted by heating in air and reacted by heating to give an oxide compound with layered structure. After the produced substance is pulverized and sufficiently washed with water and excessive lithium compound is removed, the powder is dried by heating to obtain an aiming compounded oxide A.  Conductive carbon as a conductive material and a Teflon powder as a binder in prescribed amounts, respectively, are added further to the oxide A and the obtained mixture is mixed to give a cathode mix. A pellet-like positive electrode 1 produced by press-forming the mix can cause complete reaction between an anode 2 and it and the physical properties of the compounded oxide and characteristics of a battery can be controlled.

SOLUTION: A suction cup holding member 22 equipped with two suction cups 25 and 26 is supported on an arm support member 34 via two arms 30 and 31 free of vertical motion and circumjacent movement. This arm support member 34 is connected to a first driving source 39, and a turning shaft 35 to a second driving source 42, respectively. Many pieces of films F with a seal each are stacked on a sheet holder 21, and thereby a protuverating part Fa is produced in a pile of these films F. This sheet holder 21 is provided with an upper stage part 21a holding most of these films F, and a lower stage part 21b being situated in a lower part of the suction cup 25 and lower than the upper stage part 21a, respectively.
