Abstract: PURPOSE:To prevent a big fluctuation of the photoreceptor characteristics which is caused when a packing container is opened, by enclosing a tmeperature control agent controlled at a certain level of humidity into the container along with a photoreceptor and as a result keeping the humidity in the container within a certain allowable range at all times. CONSTITUTION:The characteristics of a photoreceptor is held satisfactorily with 20-60% humidity. Thus a drier of silica alumina gel is left in an atmosphere of 25-35% humidity to control the humidity. In case when a drier controlled to 30% humidity is used, the amount of the drier required to keep the 40% humidity at 23 deg.C or 5 deg.C is obtained from the water adsorbing balanced characteristics shown in the diamgram with a packing container of 4l and in an atmosphere of 90% humidity and at 23 deg.C. The answer is 6g. And 10-30g is enclosed actually to early get the balanced state. As a result, the photoreceptor is kept in a certain range of humidity to prevent a big fluctuation of the photoreceptor characteristics which is caused by an extremely low humidity when the container is opened.

Title: Tennis ball
Inventor: YOKOYAMA TORU
IPC: A63B39/06
Filed: 1990-02-23
Abstract: PURPOSE:To remarkably improve properties such as flying safety, flying distance, hardness, elastisity, strike feeling, durability, etc., by giving a specified times of ratio to the tensile stress of melton at the equivalent elongation against the tensile stress of the core rubber. CONSTITUTION:A hard type tennis ball 1 is made in such a manner that the tensile stress of a melton 1 with an elongation range of 20-50% has the ratio of 0.9-1.1 times against the core rubber at the same elongated condition. So respective functional effects can be efficiently used without hindering the core rubber and the melton 1 with each other and hence, preferable flying capability, strike feeling, durability, etc., are obtained. When the stress ratio is over 1.1, the melton 1 is excessively hard and the elongation of the core rubber is greatly limited and so the elasticity of the ball is lowered, and hard strike feeling is also not good. On the contrary, when it is less than 0.9, the melton 1 is excessively soft and the core rubber is easily elongated and the flying capacity becomes well but the strike feeling is inferior due to the softness and durability of the core is a little lowered.

Title: Timepiece having time casting operation control function
Inventor: KUBOTA MAKI
IPC: G04G13/00
Filed: 1993-03-04
Abstract: PURPOSE:To prevent acoustic time casting from bothering appreciation of music or movie by disabling acoustic time casting operation when the ambient sound level is higher than a predetermined level. CONSTITUTION:The timepiece normally sounds a melody at a set time and a moving body, e.g. a doll, makes a performance before striking the time. When a time read out diagram 2c detects a moment immediate before the set time, ambient sound level is detected. In other words, a signal from a microphone 5a is amplified through an amplifier 5b, converted through an A/D converter 5c and stored in a memory circuit 6. A control circuit 7 compares the sound level stored in the circuit 6 with a prestored reference level. If the ambient sound level is higher than a predetermined level, acoustic time casting operation is disabled and a drive circuit 3b drives a motor block 3a to make performance only of the moving body.
