Title: Construction of air outlet of ceiling-mounted air-conditioner
Inventor: NIITSUMA FUJIO
IPC: F24F13/08
Filed: 1995-04-27
Abstract: PURPOSE: To disperse conditioned-air flowing out from an air outlet of a ceiling- mounted air conditioner which delivers air from the surface of a ceiling, and expand the area of the air outlet to increase the total amount of radiation heat emitted from the surface of the air outlet, by forming the surface of the air outlet into a curved surface. CONSTITUTION: A ceiling-mounted air conditioner 2 consists of a chamber 4, an air conditioner main body 5 and a duct 6 which are installed in a space behind a ceiling, and an air outlet 3 and a suction port 19 which are mounted on the ceiling 1. Air is conditioned by the air conditioner main body 5, sent to the chamber 4 and blown into a room through the air outlet 3. Thereby, as the conditioned air blown out from the air outlet 3 is dispersed well without a concentrated air flow onto a spot, an uncomfortable air flow is not produced in the room. In addition, as the air outlet has a curved surface, the area of the air outlet 3 is expanded, resulting in an increase in the total amount of radiation heat emitted form the air outlet 3.

Title: Data transfer device
Inventor: ADACHI SHIGEMI
IPC: G06F13/28
Filed: 1989-04-26
Abstract: PURPOSE:To efficiently execute data transfer by providing a control part to execute the mutual data transfer among a main memory and plural I/O memories between a high speed bus and a low speed bus. CONSTITUTION:In the case of the data transfer from the main memory 2 of 32-bit width to the I/O memory 9 of 16-bit width, the data transfer control device 3 reads the data of 4-bytes out of a source address (main memory), and takes it once in a data register in the data transfer control device 3, and releases a bus. After that, the source address is updated into the next address. On the contrary, in the case of the data transfer from the I/O memory 9 of 16-bits to the 32-bits main memory 2, after the data of 4-bytes is prepared by accessing the data of 2-bytes two times from the I/O memory 9, the data is written in the main memory 2. Thus, the data transfer can be efficiently executed while suppressing the fall of the throughput of a main memory bus and a CPU.

IPC: H01L23/50
Filed: 1988-04-26
Abstract: PURPOSE:To inhibit the fluctuation of supply voltage generated at the time of the switching of an output while reducing noises leaking from each of lead terminals by laminating a magnetic substance film continuing in the direction of juxtaposition of said lead terminals onto all the lead terminals in a package through an insulating film. CONSTITUTION:Beltlike magnetic substance films 30a, 30b continuing so as to respectively cross in the direction of juxtaposition of lead terminals are laminated onto the lead terminals 12a to 12d, 12e to 12h at every four through beltlike insulating films 20a, 20b. Since inductance L equivalent to the case when an inductance element is mounted in the presence of the magnetic substance films 30a, 30b as magnetic substances is generated while the magnetic substance films 30a, 30b have conductivity, electrostatic capacitance C1 to C4, C5 to C8 are generated among lead terminals and the magnetic substance films 30a, 30b by the laminated structure of respective lead terminal, the insulating films 20a, 20b and the magnetic substance films 30a, 30b, thus constituting a low-pass filter. Accordingly, unnecessary high-frequency voltage generated in an IC chip 11 can be absorbed by the inside of an IC 10, thus inhibiting the leakage of noises to the outside of the IC 10.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To make a memory operatable at a faster clock speed by activating a first control signal in the first cycle of a clock signal with the activation of a burst address control signal and activating a second control signal in a second cycle. SOLUTION: A synchronization control circuit 26 activates a latch address signal with the activation of a signal/ADS in a first K cycle to latch signal lines SA0 to SA15 in an address register 24 and outputs a new address and an address predecoder 42, a row decoder 44 activate a word line to actuate bit lines 56, 58 by the logical state of the bit stored in a corresponding memory cell 50 being on this word line. Moreover, the control circuit 26 activates a latch data signal in a third K cycle and a burst memory 20 outputs a pre- accessed data after a delayed time. Then, since a longer time is permitted in increasing bit lines as compared with a time latching the output of the address predecoder 42, a detection is made to be more sturdy.
