Patent JP-H0926281-A (JP)
Title: Heat exchanger
Inventor: HASEBE MASAYUKI
IPC: F28F13/12
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To improve heat exchange efficiency despite of a reduced number of parts by providing a plurality of spiral plates in a pipe such that a first fluid is made to flow on a plurality of spiral flow passages from one end of the pipe in the axial direction thereof to the other end thereof. SOLUTION: There are inserted four spiral plates 6 into a pipe 4 such that a cross shape is rotated in one direction around the axis of the pipe as it goes in the axial direction over the entire length of the pipe. Radial outsidemost end edges of the spiral plates 6 are brazed for example to the internal peripheral surface of the pipe 2 whereby the spiral plates 6 are fixed to the inside of the pipe 2. Cooling water as a second fluid that heat-exchanges with gas as a first fluid flows into a casing 3 and flows out of a cooling water outlet pipe 5b after passage through the pipes 2.  Since the gas passing through the inside of the pipe 2 advances in the form of a spiral flow owing to the spiral plate 6, the flow speed in the vicinity of the internal peripheral surface of the pipe 2 is increased to improve the efficiency of heat transfer to the spiral plates 6 and the pipe wall of the pipe 2.

Title: Sucking fixing carrying sheet
Inventor: WANO TAKASHI
IPC: H01L21/683
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a carrying sheet capable of sufficiently responding to a reduction in size and weight in a green sheet, without changing any facilities on the like of a manufacturing process, by using a porous carrying sheet whose surface to be a contact surface with a sheet to be sucked has a porosity and a roughness of respective specific values and moreover whose air permeability as a whole is a specific value. SOLUTION: A porous sheet 2 is used whose surface to be a contact surface with a green sheet 3 of a sheet to be sucked has a porosity of 40% or lower and has a roughness of 1 μm or lower. This prevents the green sheet 3 from coming in the pores in the sheet 2, when the green sheet 3 is sucked because the pores are very small and the occurrence of defects, such as uneven spots or flaws on the surface of the green sheet 3, because the surface of the sheet 2 is smooth. Furthermore, if air permeability in the direction of thickness of a sucking fixing carrying sheet 2 is set at 1 cm3/cm2/sec or lower, it is easy to conduct suction, fixation, and detachment of the green sheet 3 without affecting the cycle time of manufacturing process (time required to suck and detach the green sheet 3).

Title: Spread spectrum communication equipment
Inventor: HIROSE KOJI
IPC: H04B1/707
Filed: 1993-07-20
Abstract: PURPOSE:To attain high speed frequency hopping with simple configuration by allowing a transmitter side to phase-modulate a direct spread signal in response to a 1 logical state or a combined logical state of plural bits of transmission data and reproducing the transmitter side data by pattern matching in the direct spread demodulation of the receiver side.

When an input signal, that is, an output of a mixer 10, that is, a frequency hopping demodulation signal is a pattern A, then the filter 12 outputs a coincidence signal, and conversely when the input signal is a pattern B, the filter 13 outputs a coincidence signal. A data discrimination circuit 14 outputs a synchronizing signal to a synchronization detection circuit 15 every time the coincidence signal is provided from the two matched filters to establish the synchronization of the frequency hopping demodulation stage. As a result, the data discrimination circuit 14 reproduces the transmission data.
