Title: D/a converting circuit
Inventor: EZAKI TAKAFUMI
IPC: H03M1/68
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To execute highly accurate D/A conversion without depending on the variation frequency, etc., of an input digital signal. SOLUTION: A D/A conversion circuit 2 includes a pulse modulation circuit 4, an adding circuit 114, a D/A converter 116 and a filter 118. The circuit 4 generates 1-bit digital signal 6 varying a logic value by a period corresponding to the value of the low-order m-n bits of the input digital signal 102 of m-bits, and the circuit 114 synchronizes higher-order n-bits except for the low-order bits of the signal 102 and the signal 6 generated by the circuit 4 with a clock signal 122 to digitally add them. The converter 116 converts the output signal of the circuit 114 to an analog signal and the filter 118 removes high frequency components from the output signal of the converter 116 to output it as a final converting result. Then, the circuit 4 consists of a delta/sigma converting circuit and generates the signal 6 closer to an ideal.

Title: Baking oven
Inventor: KAWAI KOJI
IPC: A47J43/046
Filed: 1988-09-30
Abstract: PURPOSE:To prevent the temperature of a bread case from rising up to a high temperature in a baking stage by deciding that the bread case is empty when the rising speed of the detected temperature of a temperature sensor is at a certain fixed value or below in a stage of mixing and kneading dough. CONSTITUTION:When there is no dough in the a bread case 19 and the case is empty, since the mixing and kneading blade 23 is rotated in vain in the bread case 19 in the kneading stage, friction heat is not generated, the temperature of the bread case 19 is hardly raised, thereby, rising value DELTAT of the bread case temperature is made lower than a decided value DELTATO, and conditions to stop an operation are attained. Consequently, since the operation is stopped in the kneading stage to be the first among a series of bread making processes, for the baking oven, the operation is automatically stopped even when the operation is executed while the material is forgotton to be put in. Thus, the accident that a bearing 20 and the mixing and kneading blade 23 are deteriorated by being exposed to the high heat because the bread case 19 is baked without dough in the baking stage, that the shaft 21 is fixed and that the mixing and kneading blade 23 is broken can be prevented.

Title: Multiple optical connector
Inventor: OBARA YUICHI
IPC: G02B6/36
Filed: 1985-11-06
Abstract: PURPOSE:To prevent the leak light generated on butt surfaces from affecting adjacent optical fibers by serrating the front end face positions of the adjacent optical fiber insertion holes so that the end faces are brought to different positions. CONSTITUTION:A multiple optical connector 1 is provided with the optical fiber insertion holes 2, 2... at prescribed intervals. The connector 1 is provided with the front end faces 3 having the insertion holes 2 so as to be serrated to ruggedness for each of the end faces on the butt end face side thereof. The connector 1 is formed by molding of a molding resin. Since the positions of the adjacent end faces are different, the intrusion of the light leaking from the optical fiber into the adjacent optical fibers is obviated with the optical fibers 2, 2... butted and connected with each of the end faces as the light is blocked by the wall surface stepped from the contiguous end face even if the light propagating in the optical fibers leak from the contact surface of the optical fibers. The connector 1 is thus miniaturized.

When (n) is an even number in formula I, the compound is ferroelectric, and when it is an odd number, the compound is anti-ferroelectric. This material has a wide low-temperature region of a liquid crystal state because of the presence of the siloxane liquid crystal. Further, when it is mixed with a ferroelectric liquid crystal compound, it can attain a low saturation voltage.  When this material is ferroelectric, it is combined with a dichroic dye to form a guest/host liquid crystal which gives a liquid display element having a tilt angle of 45 deg., high contrast and a wide angle of visual field. When the material is anti-ferroelectric, it is suitable for symmetrical drive. By virture of the features of the material, it can give an excellent liquid crystal display element by various methods.
