IPC: H03F3/00
Filed: 1983-12-14
Abstract: PURPOSE:To simplify circuit constitution, to facilitate adjustments and to improve linearity by connecting switching circuits and primary windings of a pulse transformer in series and impressing an input voltage between both terminals, and rectifying and smoothing the output of the secondary winding of the pulse transformer and obtaining an output voltage. CONSTITUTION:Switching circuits 1a and 1b are turned on and off with the output of an oscillator 2, and a voltage k(Vi+Vc) proportional to the sum voltage Vi+Vc of an input voltage Vi and a correcting voltage Vc is impressed to the primary windings 4a and 4b of a pulse transformer 3. Then, an AC voltage VAC=k'(Vi+Vc) proportional to the voltage Vi+Vc is induced across the secondary winding 5. This voltage is rectified by a diode bridge and smoothed by a smoothing capacitor to obtain the output voltage Vo. The correcting voltage Vc is added to the input voltage Vi to inhibit operation in the small current region of the diode bridge even when the input voltage Vi is low, preventing deterioration in linearity. Further, adjustment are only made so that the on-off period of the switching circuits is much shorter than the period of the input voltage.

Title: Measuring method for ice amount in ice heat storage system
Inventor: KUROSAKI YUKIO
IPC: F25C1/00
Filed: 1989-09-12
Abstract: PURPOSE:To measure continuously the ice amount and make the occurence of errors difficult at the time of ice making and ice melting by a method wherein the content rate of ion materials concentrated and raised following the formation of ice in a heat storage vessel is measured from the change in electric conductivity by a conductivity meter and an ice charging rate is indirectly measured. CONSTITUTION:In the cooling water inside a heat storage vessel 1 various kinds of ion materials are contained and the ice formed in a supercooling dissolution unit is, however, formed by only pure water and in it various kinds of ion materials are not contained. Accordingly, as far as the initial water amount is not changed, the content of the ion materials is constant and so as the formed amount of ice increases, the ion materials in the water which is not frozen are concentrated and the content rate of the contained ion materials for this water is raised. As the ion materials have electric conductivity, a conductivity rate is proportional to the content rate of the ion materials in the range of about pH 5-9 for the water of the same amount in the same water system. Then, when the change of the conductivity rate of supplied cooling water from the vessel 1 is measured by a conductivity meter 6, the change in the content rate of the ion materials, that is, the amount of ice can be measured indirectly.

Title: Reservation connecting system for mobile machine
Inventor: SHINDO SHUICHI
IPC: H04B7/26
Filed: 1985-10-21
Abstract: PURPOSE:To realize a reservation connection without increasing the burden of a control device under the same control as a usual immediate connection, by storing a call connecting signal for a reservation in a mobile machine side instead of an exchange. CONSTITUTION:When a call is executed from the mobile machine 1, if the connection cannot be executed due to reasons why a line is congested, a line state is bad, etc., a call receiving signal is not received. When it call subscriber depresses a reservation button at the mobile machine 1, a call connecting signal such as a transmission signal required for a call, a dial signal, etc., are stored in a memory in the mobile machine 1. As a matter of fact, this call connecting signal is stored temporarily in a buffer at the time of a call operation, and it is transferred to the memory. The mobile machine 1 reads out and sends out the call connecting signal of said memory at some time interval, and at the time point when the line congestion, etc., are dissolved, or the line state is recovered by the movement of the mobile machine, an exchange 4 transmits a call receiving signal, and also executes a call connection control. In this operation, it may suffice that a base station 2, a radio line control device 3, and the exchange 4 execute the connection control without being different from a usual immediate connection.
