Title: Audible calling signal preparing equipment
Inventor: OKUYAMA SATORU
IPC: H04M1/00
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To inform a user of an incoming-call by means of a voice message or a calling sound which are registered by the user himself and are remarkably unique. SOLUTION: Some patterns of the speech signals or the voice messages inputted from MIC 1 are encoded by COD 2 and stored in MEM 3 by the control of CTL 9. Then the user previously select-specifies which of patterns of the voice calling signals or the voice messages should be used at the time of call- incoming in consideration of the using place and the using time zone of a portable terminal equipment by operating SEL 4. When DET 5 detects an incoming- call to the portable terminal equipment from the line in this state and informs CTL 9 of it, CTL 9 reads encoded voice data select-specified by SEL 4 from MEM 3 and sends it to CNV 6. CNV 6 reproduces voice from this encoded voice data and outputs it from SPK 7.

Title: Concrete regenerating method
Inventor: ASHIDA KIMINOBU
IPC: E04G23/02
Filed: 1992-12-10
Abstract: PURPOSE:To make safe operation of regenerating the concrete by making the current feed with voltage suppressed between inner voltage which uses a steel material inside the concrete as an electrode, and an outer electrode installed over the surface of the inner electrode, and supplying an electrolytic solution while the current is fed between the two electrodes. CONSTITUTION:An electrolytic solution is allowed to permeate a concrete with elapse of the time while the DC current is fed into the concrete in order to remove alkaline substance or salts from the concrete. The current may be either of the DC and AC, and the polarity of DC may be changed any during current feed. Thereby the voltage value as required can be suppressed, which allows preventing the worst occurrence which might be mortal even in the event of electric shock.

Title: Centrifugal type friction engagement clutch at vehicle starter
Inventor: SAKAKIBARA SHIRO
IPC: F16D47/06
Filed: 1988-12-30
Abstract: PURPOSE:To increase a torque capacity without increasing the weight of a weight, by arranging a constituting in which centrifugal force acting on the weight is increased by a lever ratio and acts on a friction shoe. CONSTITUTION:A weight assembly 6 is equipped with a predetermined lengthed arm 6b having a weight 6a at the tip portion, and supports its base end portion X swingably by means of a clutch disk 2, and in addition, presses pushingly and connects to a friction shoe 5 a base end portion vicinity Y on the weight 6a side of the arm 6b. When centrifugal force F acts on the weight 6a in an outer diameter direction as the disk 2 rotates, the arm 6b swings in the outer diameter direction with the base end portion X as a center, and is magnified by a lever ratio b/a between a distance (a) which is from the base end portion X to an acting on point Y, and a distance (b) which is to a force point (a weight gravity center point) F, and acts on the friction shoe 5. As a result, the friction shoe 5 comes into contact with a drum 3 with a large pushing pressure, and has a large torque capacity since at the time of a low speed rotation.
