Title: Material for speaker box
Inventor: MURATA KOSAKU
IPC: H04R1/02
Filed: 1988-12-16
Abstract: PURPOSE:To realize a speaker system having an excellent acoustic characteristic without generating abnormal sound noise by using a material being a mixture of a thermoplastic or thermosetting synthetic resin and a whisker having a high elastic modulus made of a zinc oxide in which crystals are grown from the center to four different directions as a material for a speaker box. CONSTITUTION:A material being a mixture of a thermoplastic or thermosetting synthetic resin and a whisker having a high elastic rate made of a zinc oxide in which crystals are grown from the center to four different directions is used for a material for a speaker box. Since the bending elastic rate is large, no abnormal sound noise is caused, and further a speaker box is realized in which the sound pressure versus frequency characteristic of the speaker is made flat and the distortion factor is reduced.

Title: Electronic clinical thermometer
Inventor: MURAI TOSHIO
IPC: G01K7/00
Filed: 1988-12-16
Abstract: PURPOSE:To obtain a small-sized inexpensive clinical thermometer having good assembling properties, by inserting a circuit board in a main body case from the rear end open part thereof and grasping a part of the front of the circuit board by the grooves provided to the inner wall of the main body case. CONSTITUTION:When a power supply switch 9 is pushed down, a circuit board 3 receives downward force by conductive rubber 9b but, since said force is supported by the tongue part 11a of a battery case 11, the board 3 is not deformed in the direction vertical to the surface thereof. When a battery 10 is replaced, the case 11 is pulled off rearwardly from a main body case 2 and a new battery 10 is mounted to said case 11. Herein, when the case 11 is pulled off, the board 3 is ready to be drawn out rearwardly along with the case 11 by the engagement of the protruding part 12a of a terminal 12 for a negative pole with the hole of the board but, since the boss 17 of the back lid 15 fixed to the case 2 is engaged with the hole of the board 3, the board 3 is not moved. Therefore, it is prevented that a lead wire is disconnected or the switch 9 receives mechanical damage.

IPC: G11B15/44
Filed: 1992-11-05
Abstract: PURPOSE:To simplify the mechanism by providing a tape take-up reel, a driving mechanism for turning flywheels, a head plate capable of reciprocating a head mechanism, a change gear and a mechanism for controlling transmitting driving power. CONSTITUTION:When a program change is made from reverse to forward order, a capstan driving motor 31 is reversely rotated, and the flywheels 27F and 27R are rotated via a belt 34. The change gear 46 is rotated by rotating this wheel 27F. A selecting plate 45 itself is rotated in the rotating direction of the gear 46, and a selecting gear 47 is meshed with a power changing gear 24 by turning the plate 45 itself. Rotational force of the wheel 27F is transmitted to the gear 24, and a change plate 23 is moved to the left by rotating the gear 24. A change rack 55 is moved to the left by moving the plate 23, and a head rotary gear 52 is rotated by a rack tooth part 55a to rotate a head 51. Thus, since the driving mechanism is forwardly and reversely rotated, the structure is simplified.

Protrusive protuberances 4 are provided in three positions at the bottom 3. Each of the protuberances 4 is formed in a hemispherical shape in a height of 0.5-10mm. In the case of providing the protuberances in four or more positions, the protuberances must be provided at the bottom 3 in positions on lines intersecting a sealed part 2 approximately at a right angle. Thereby, the container can be prevented from becoming unsteady when placed on a flat board, and unsteadiness in standing can be improved.

Abstract: PURPOSE:To prevent a defect at a head of an input and a click noise sound by giving a reset signal of a small level to the D/A converter when an input signal reaches a 0 level to allow a bit pattern to be converged to a fixed pattern and releasing resetting succeedingly. CONSTITUTION:A zero detection circuit 41 outputs 1 when an input data Di is 0 and outputs 0 when the input data Di is other than 0. A zero count circuit 42 counts up when an output of the circuit 41 is at 1 and outputs 1 when the circuit 42 counts up by, e.g. 2<16>. The circuit 42 resets the count when the output of the circuit 41 is 0. A dither counter 43 outputs an AC dither signal at a prescribed period and a dither stop circuit 44 samples an output of the circuit 42 synchronously with the output of the counter 43. An AND gate array 46 masks the output of the counter 43 by an inverted output of the circuit 44. A 1-bit feedback data is subject to bit expansion by an expansion circuit 52 and added to the output of a delay circuit 48 by a full adder 53. A 1-bit quantizer is realized by extracting the MSB being the result of the sum of full adders 61, 62 as an output data D0.

IPC: H03D1/10
Filed: 1988-12-20
Abstract: PURPOSE:To obtain a detecting signal not being affected by a temperature by connecting the cathode of a diode for temperature compensation with the same specification as that of a diode for detection to the input terminal on the reference voltage applying side of a comparator, connecting a second resistor between the input terminal and the ground, and applying a reference voltage on the anode side of the diode for temperature compensation.
