Title: Character processor
Inventor: HATANAKA MITSUYOSHI
IPC: G06F3/0481
Filed: 1983-08-29
Abstract: PURPOSE:To eliminate the need for mode switching done by a key input operator by switching automatically the operation to a mode equal to the mode of a character where a cursor is positioned in case a key input is carried out after a shift of the cursor. CONSTITUTION:Various keys of KATAKANA (square form of Japanese syllabary), HIRAGANA (Japanese syllabary), etc. are arranged on a keyboard 5 to set various keys and modes for indication of the cursor shift. When a cursor shift key is pushed, the contents of a cursor register CR in an RAM14 are rewritten by a prescribed procedure in response to the type of the key. Then the cursor is shifted on a screen of a CRT device 8. If the cursor is positioned at HIRAGANA, for example, a mode register MODR in the RAM14 is changed to a HIRAGANA mode regardless of the preceding mode. Thus it is possible to eliminate the need for mode switching done by a key input operator.

Title: Power amplifier for radio transmitter
Inventor: NAKANISHI HIDEKAZU
IPC: H03F1/02
Filed: 1990-06-18
Abstract: PURPOSE:To ensure a power control range with a high efficiency and a broad band by providing a main power control stage comprising two stages of final amplifier elements and a sub power control stage comprising a pre-stage amplifier element of the said main power control stage and applying a common control voltage to a control terminal of each amplifier element of the main power control stage so as to control output power in the said main power control stage. CONSTITUTION:An output power of a power amplifier is controlled mainly by a main power control stage D2 and an auxiliary output power to supplement a control range of the said main power control stage D2 is controlled by a sub power control stage D3. Thus, when a control power level is very small and a voltage at a control terminal (c) of the main power control stage D2 is decreased to nearly 1V, the voltage at the control terminal (c) of the sub power control stage D3 is decreased. Then an input power level of the main power control stage D2 is decreased to increase the voltage at the control terminal (c) of the main power control stage D2 relatively thereby avoiding the occurrence of unstable operation.

Title: Nonaqueous solvent cell
Inventor: TANAKA KOUICHI
IPC: H01M6/16
Filed: 1982-09-10
Abstract: PURPOSE:To prevent shortcircuit by fitting a porous ring over the circumferential side face of a positive pole thereby suppressing expansion of positive pole and enabling conduction of electrolyte to the positive pole. CONSTITUTION:A porous polypropylene ring 111 is fitted over the outercircumferential face of first positive pole 21 of disc shape contained in an outer can 1 while porous polypropylene rings 112, 112' are fitted over the outercircumferential side face and innercircumferential side face of second positive pole 22 of doughnut shape. Consequently expansion of the positive poles 21, 22 due to discharge is suppressed to prevent shortcircuit with the negative pole 6 or negative pole lead terminal 10. Since the porous polypropylene ring has liquid permeability, even when the positive poles 21, 22 have expanded to bring shortage of electrolyte in the positive poles 21, 22, electrolyte filled in the gap of the outer can 1 or the air gap around the negative lead terminal 10 will be fed through the rings 111-112' resulting in improvement of discharge utility.

Title: Apparatus and method for measuring radioactivity of ion eluent
Inventor: GINTAA DEIITSUERU
IPC: G01T1/167
Filed: 1991-05-31
Abstract: PURPOSE: To measure radiation continuously with relatively high accuracy and high detective sensitivity. CONSTITUTION: This device includes a valve device 4 which can feed flowing ion eluate into at least one radiation detector 8 from a reference passage 6, and the radiation detector 8 measures the amount of radiation under such a condition as the ion eluate is static. Retention time of the ion eluate in the radiation detector 8 is extended to a large extent, and measuring time lengthens. For example, if a counting rate is 1 per second and the retention time in the radiation detector 8 is 10 seconds, the fluctuation range (σ) is 1/√(1×10)×100=31.6%. However, the retention time can be doubled, for example 20 seconds, and the fluctuation range (σ) is 1/√(1×20)×100=22.3%, which is smaller than the case of 10 seconds. Therefore, it is possible to measure the amount of radiation under such a condition as statistic error is decreased remarkably.
