IPC: H04H60/47
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent errors in combination of a symbol information group and a symbol name group. SOLUTION: A transmitter 3 adds identification data, equal to the error detection code of one of a symbol information group and a symbol name group data group, to the NULL data part of the other data group, and superimposes a signal to be transmitted including this on an FM broadcast signal, and transmits it.

IPC: G01N33/86
Filed: 1981-12-17
Abstract: PURPOSE:To achieve a better separation of serum from blood clot in a centrifugal manner while reducing the time required for the blood coagulation with a promotion of the blood coagulation by having a surface-active agent and an adsorbing inorganic substance coexisting on the surface of a carrier. CONSTITUTION:A non-woven cloth made of regenerated cellulose is impregnated with a methyl alcohol dispersion liquid containing 0.1wt% of sorbitane monostearate and 1wt% of finely granular silica and dried to obtain a blood coagulation promoter. The sorbitane monostearate presents on the surface of the non- woven cloth at a rate of 1X10<-5>g/cm<2> while the silica at a rate of 1X10<-4>g/cm<2>. The agent thus obtained is put into acrylic resin spits for 10ml. It is also put into spits in the amount of 4cm<2> and then, 8ml of fresh blood is injected into both groups of spits to evaluate the blood coagulating property, the separation of serum and the yield of cerum. It is demonstrated that this hlood coagulation promoter achieves a very quick blook coagulation, a very good separation of serum, eliminating blood elution and a better yield of serum.

Title: Dc-dc converter
Inventor: IKEUCHI HIROSHI
IPC: H02J1/12
Filed: 1991-07-19
Abstract: PURPOSE:To provide a zero-cross forward type DC-DC converter in which loss is nullified at the time of turn ON of primary switch. CONSTITUTION:Driving circuit on the primary of a transformer 4 comprises a primary switch, i.e., a first MOSFET 6, an auxiliary switch, i.e., a second MOSFET 10, and a power supply 12 whereas the output circuit on the secondary of the transformer 4 comprises a secondary switch, i.e., a third MOSFET 11, and a choke coil 16. ON operation of the third MOSFET 11 is interlocked with OFF operation of the first MOSFET 6 so that no current flow through the secondary coil 3 when the first MOSFET 6 is turned OFF thus preventing induction of voltage in the primary coil 2 due to the current flowing through the secondary coil 3. Consequently, the operating voltage is prevented from rising due to the induced voltage when the primary switch is turned ON.

IPC: H04R1/28
Filed: 1982-11-22
Abstract: PURPOSE:To prevent deterioration in sound quality by using two woofers and arranging them to the node of up/down and left/right sound pressure mode to eliminate a standing wave generated at the reproducing band of the woofers and to prevent the disturbance of the sound pressure characteristic due to the standing wave. CONSTITUTION:Assuming the height of the inner size of an enclosure 1 to be an H, the width be a W and the depth be a D, then the two woofers 3a, 3b driven at a high cut-off frequency fc are arranged on a buffle surface 2 of the enclosure 1. One center of the two speakers 3a, 3b is arranged on a center line bisecting the height of the buffle surface 2 and the other center is arranged on a line is spaced by an H/4 in parallel with the center line. The relation of the inner size of the enclosure 1 is taken as H>=W, W<=c/fc and D<=c/2fc (where c is the sound velocity). The arrangement in this way eliminates the standing wave generated at the reproducing band of the speakers 3a, 3b and prevent the deterioration in the sound quality.

Title: Battery charger
Inventor: SUGAWARA YASUHISA
IPC: H02J7/10
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To complete the charging of a battery irrespective of the operating state on a main body side, by preventing the stoppage of the charging even when the dropping of the terminal voltage of the battery is detected while a status signal is inputted. SOLUTION: A -ΔV detecting circuit 12 intermittently inputs status signals from a status terminal and, at the same time, monitors an anode terminal (+) and, when the voltage at the anode terminal (+) drops and no status signal is inputted, outputs a charging terminating signal to a charging circuit 11. When the voltage at the anode terminal (+) drops and a status signal is inputted, the circuit 12 does not output the charging terminating signal to the circuit 11. Since the charging of a battery is not stopped even when the terminal voltage of the battery drops while the status signal is inputted, the battery can be charged continuously even when the terminal voltage of the battery inadvertently drops when the battery is charged, while a load circuit which outputs the status signals during operation is operated.

Abstract: PURPOSE:To remove the positional shear of a spot on a recording face by expanding or contracting the beam width of one beam out of laser incident beams condensed by 1st and 2nd prisms having different refractive indexes and refractive index dispersion rates and forming a fixed angle between the optical axis of a projected beam and the normal of a projection face. CONSTITUTION:A laser beam from a condenser lens 2 is made incident upon two triangular prisms 3, 4 having different refractive indexes and refractive index dispersion rates respectively and setting respective vertical angles to beta and gamma. At that time, an incident angle and a refractive angle are alpha and theta at an end face 3a, and at an interface 3b and an end face 4c, the incident angles are theta+beta and phi-gamma and the refractive angles are phi and psi respectively. The beams are reflected by a recording face 7 and made incident upon the prisms 4, 3 again. At that time, the incident angle and refractive index at the end face 4c are psi and phi-gamma and the beams are reflected by the interface 3b and advanced to a detector. When the materials and shapes of the prisms 3, 4 are properly selected, the change of refractive angle at the end face 4a can be canceled by the changes of the refractive angles at the interface 3b and the end face 4c. Consequently, the spot position on the recording face can be prevented from being shifted.
