Title: Tennis ball
Inventor: OKONOGI YASUAKI
IPC: A63B39/00
Filed: 1990-04-10
Abstract: PURPOSE:To provide a feltless and pressure-free tennis ball in no way inferior to a pressurized ball in a ball hitting feeling by blending an organic azo foaming agent with a raw rubber composition to satisfy a determined weight for controllably determining the thickness of a core ball. CONSTITUTION:A compound rubber compounded of 100 parts of a raw rubber made of a natural or synthetic rubber or a blend of both with 5-19 parts of ordinary additives, a vulcanizing agent, an accelerator and an organic azo foaming agent is heated and vulcanized to provide a foamed body which is used for a core of a tennis ball having 5.0-10.0(mm) of thickness and no melt-on cover. When the foaming agent exceeds 19 parts, it foams too much. Therefore, a good tennis ball cannot be obtained owing to the deterioration of the hardness and strength as physical properties of rubber. When it is under 5 parts, the core thickness becomes less than 5.0(mm) so as to satisfy the standard weight of the tennis ball so that the tennis ball cannot be provided with a good ball hitting feeling.

Title: Current detection circuit and power unit
Inventor: KATO HIROJI
IPC: H02M7/06
Filed: 1990-04-09
Abstract: PURPOSE:To always obtain an output in proportion to an input current with a low loss and simple configuration by exerting current mirror connection onto transistors (TR) whose base and collector are connected, while combining the TR and a resistor as required. CONSTITUTION:For a TR4, the collector and the base are connected and a resistor 1 and a current source 6 are respectively connected to the emitter and the collector, and for a TR5, resistors 2 and 3 are connected to the emitter and the collector. The bases of these TR4 and 5 are coupled each other and the current mirror connection is exerted upon them. When a current Io flows from a current input terminal 7, the collector current of the TR5 is made proportional to the current Io and between detection terminals 9 and 10, a voltage VS in proportion to the collector current is generated and detected. In this case, there is a base/emitter join part in a closed loop including the resistor 1, where the current Io flows, and this part becomes an active area, where the TR4 and 5 executes linear operations, by canceling various characteristics. In such a case, a voltage in proportion to the current Io of the resistor 1 is not included. Thus, the output can be always obtained with the loss and the simple configuration while reducing the number of parts.
