Title: Allocating method for data storing area of memory
Inventor: KOBAYASHI KAZUYA
IPC: G06F12/02
Filed: 1987-05-06
Abstract: PURPOSE:To omit multipliers and adders and to improve the availability of a memory by dividing an address space of the 2-dimensional data into two scanning address spaces equal to the power of 2 to allocate both address spaces to two areas of the memory. CONSTITUTION:For a memory storing the 2-dimensional data, e.g., a KANJI (Chinese characters) ROM, the number of addresses of a scanning address SA space is not equal to the power of 2 against a single piece of KANJI data, e.g., the (24X24)-bit data. In such a case, the SA space is divided into two SA spaces equal to the power of 2 and the (24X24)-bit data, for example, are rearranged in (36X16) bits, the SA space is divided into a 1st SA space equal to the SA number 32 (=2<5>) and a 2nd SA space equal to the SA number 4 (=2<2>). Then the 1st SA space is continuously allocated to a single area of the ROM, e.g., the lower level address side and the 2nd SA space is continuously allocated to another area of the ROM, e.g., the higher level address side. Thus the KANJI data can be stored into the ROM with no gap.

Abstract: PURPOSE:To realize a higher processing speed by providing a data conversion part for converting recording density information contained in recording data to start/end data specifying a time, a storage part for storing the data in addresses, and a signal generation part for generating a recording signal. CONSTITUTION:In a data conversion part 2, recording density information contained in recording data Dp is converted to two-point data, i.e., start/end specifying data (ds), (de), for specifying a time of a recording signal. In a storage part 3, the data is written in addresses corresponding to the start/end specifying data (ds), (de) shown by '1'. At the time of recording, the start specifying data (ds) is read out to be held in a data holding circuit 6 through an EX-OR circuit 5, simultaneously being applied to a thermal head H as a recording signal Sp. Next, the data holding circuit 6 applies '1' to the EX-OR circuit 5, and the EX-OR circuit 5 outputs '1'. On the end specifying data (de), '1' is also applied to the input part of the EX-OR circuit 5, and the EX-OR circuit 5 outputs '0'. The data (de) serves as a recording signal containing information of a '1' data continuous time as a unit of heating a thermal head H.

Title: Liquid level rise prevention device for mixture of refrigerator oil and refrigerant in closed type compressor
Inventor: NAKAOKA MASASHI
IPC: F04C28/26
Filed: 1990-04-25
Abstract: PURPOSE:To maintain a constant liquid level, whether a closed type compressor is at rest, in operation or otherwise, and improve the reliability of the compressor by making the compressor continuous to a liquid reservoir section at one side thereof via a communication pipe and another pipe fitted with a nonreturn valve. CONSTITUTION:When a closed type compressor is at rest, a refrigerant is dissolved in refrigerator oil 7 in a closed vessel 1, and a liquid level in the vessel 1 increases accordingly. Actually, however, the increased refrigerator oil 7 is made to flow to a liquid reservoir section 4 via a communication pipe 5 fitted at an allowable liquid level, thereby preventing an increase in liquid level. On the other hand, when the compressor is operating, the refrigerator oil 7 is as well carried to a system, together with delivered gas and, therefore, the liquid level drops. In this case, the liquid is made to flow from the liquid reservoir section 4 to the closed vessel 1 having a lower liquid level. In addition, the liquid level in the liquid reservoir section 4 becomes minimum during the operation of the compressor. Even when the liquid level in the vessel 1 increases, therefore, no liquid reversely flows to the liquid reservoir section 4, due to the nonreturn valve of a pipe 6, thereby maintaining a constant liquid level in the closed type compressor.

Title: Protection relay device of dc transmission line and failure detection circuit of dc transformer
Inventor: SUGIURA HIDEMASA
IPC: H01F38/40
Filed: 1994-05-24
Abstract: PURPOSE:To detect the failure in a DC transformer with a simple operation and a high sensitivity and to prevent a relay from malfunctioning by judging that a means for introducing a voltage to a protection relay device failed when the current difference between own and target terminals is equal to or less than a certain value and a voltage change is equal to or more than a certain value. CONSTITUTION:A simple difference current detection means 7 detects a single difference current by inputting own terminal and target terminal currents AA and AB and a means 8 for calculating the amount of charge current compensation inputs a voltage VA of the own terminal and calculates the amount of compensation for the charge current. When the level of the change in voltage between the amount of own terminal voltage at a current time and the amount of own terminal voltage before sampling is equal to or more than a specific value, the simple difference current is compared with the level of the specific value. An operation means 10 for judging the failure of a transformer judges that a transformer failed when the own terminal voltage changes exceeding a specific value while the simple difference current is equal to or less than a specific value, locks relay output and at the same time outputs an alarm to the outside, thus detecting the failure in the DC transformer properly and using a simpler amount of operation than before.

The hull is made of foaming styrene so that a hull shape can be easily worked by a user, and the respective modules 1 and 2 are constituted so as to generate force at underwater navigation/floating time by using the reaction by sending out water in the vertical direction of the hull. That is, the respective water sending-out modules 1 and 2 are constituted by having a screw 10 rotated by obtaining motive power from a driving motor 6 via a rubber belt 5. In the hull, a hull attitude is stabilized by using the rival relationship between buoyancy of the foaming styrene and gravity acting on a battery 8. Propelling water sending-out modules 3, 4 are arranged in a rear part of the hull.
