Title: Filter member and filter using same
Inventor: YAMAMOTO AKIMASA
IPC: B01D39/20
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To facilitate disposal as well as to reduce cost by forming a filter member for removing gaseous components, dust and oil components in gases predominantly from an expanded graphite sheet. SOLUTION: Expanded graphite can easily capture impurities such as gaseous components, dust and oil components in gases, also has the function of a molecular sieve and can therefore capture the gaseous components on the molecular level. Since expanded graphite has particularly high surface activity and a lipophilic surface, it is excellent in property of adsorbing particulates of oil components, etc., or particulates having lipophilic surfaces such as soot. The desired filter is obtd. using an expanded graphite sheet. At this time, a filtermember 1 is formed so that recesses 3, protrusions 2 and/or through holes or concavities are provided to the surface to increase the surface area of the filter member 1 coming in contact with gases.  A bent structure is preferably adopted as the recesses 3 and the protrusions 4 to easily form the rugged shape and gas passages are easily ensured at the time of forming the filter.

IPC: A61B5/00
Filed: 1993-04-15
Abstract: PURPOSE:To detect the sleeping person's parts where blood circulation turned low and notify it as bedsore parts. CONSTITUTION:The movement of a body is detected wit a detecting device for body movement 1a-1z, and whether the movement is large or small, and whether there is a sleeper or not, etc., are judged with a judging device 4 through a signal transforming device 2. If the body movement is judged small, the judging device 11 for blood circulation judges whether the quantity of blood circulation is desirable or not through a signal that reflects the quantity of blood circulation selected from among outputs outputted from the signal transforming device 2. If the blood circulation is judged to be undesirable, its continuation time is measured with the second measuring device, and if the measured time is more than a definite value, it is notified as a bedsore part. Because the notification timing is based on the quantity of the blood circulation of the part where not body movement is observed, the information is early and accurate as bedsore part information.

Title: Communication controller
Inventor: MATSUDA SUMIO
IPC: H04L29/08
Filed: 1982-05-26
Abstract: PURPOSE:To avoid the deterioration of transmission efficiency with an optimum frame length despite the deterioration of circuit quality, by changing dynamically the frame length in response to the quality of the transmission line. CONSTITUTION:The data of a receiving circuit 10 is received by a frame receiving circuit 2. When a transmission error detecting circuit 3 detects a transmission error, the corresponding frame is disused. This is informed to an error counter 5. The fact that the counter reaches the prescribed value is informed to a transmission frame producing part 8 as well as to a timer 7. The part 8 sets the subsequent transmission frame length at half the preceding length and at the same time supplies the signal to a timer 6 through a resetting period alteration indication line (f). The timer 6 shortens the reset cycle of the counter 5 by a fixed rate and counts up autonomously a built-in counter. Then the timer 6 is reset when the counter reaches the prescribed value before resetting and at the same time supplies the signal to the part 8. The part 8 changes the frame length at that time point to the double value and transmits the subsequent frames.
