Title: Bath system
Inventor: IKENAGA MITSUO
IPC: A47K3/00
Filed: 1993-06-08
Abstract: PURPOSE:To prevent freezing in the winter sensor by constituting the system so that a water level detected by a sensor is stored as a reference when bathing water is stored up to height of the part opened on the bathtub wall surface in a water circuit such as a hot water pouring circuit, and opening water discharge value to discharge water when the water level becomes lower than the reference. CONSTITUTION:Hot water is supplied to a bathtub 1 through a pump P from a hot water heating exchanger 31 and an additional heating heat exchanger 21. In the case bathing water is stored up to height of the part opened on the bathtub wall surface in a water circuit such as a hot water pouring circuit, a water level detected by a water level sensor 22 is stored in a control circuit 5 as a reference water level. When bathing is finished and a gas burner of the heat exchangers 21, 31 is extinguished, and water is discharged by opening a water discharge plug 11, the water level sensor 22 detects a fact that the water level falls from the reference water level, and the control circuit 5 opens a value 25 through a water discharge circuit 4, and discharges water stored in the water circuit. In such a way, residual water in the water circuit is gone, and damage caused by freezing in the winter season is prevented.

IPC: G03G15/04
Filed: 1989-05-31
Abstract: PURPOSE:To obtain an excellent half tone characteristic by using a beam diameter modulator for limiting an area of an emitted light beam in parallel rays emitted from a light source. CONSTITUTION:This recorder is constituted of a light source 31 for generating parallel rays, a beam diameter modulator 34 for controlling a passing area of the parallel rays, an incident lens 35 for varying a diffracted light from the beam diameter modulator 34 to parallel rays, an optical deflector 37 for varying the direction of the parallel rays, and an image forming lens 38 for bringing a deflected light to image formation on a recording body 39. That is, the intensity of a scanning light beam is not modulated but the diameter of an emitted beam is modulated by a beam diameter modulator 34. Accordingly, the spot diameter can be varied in proportion to whether the diameter of the emitted beam is large or small, and the maximum intensity of the spot on the recording body 39 becomes the same degree. That is, the intensity to the recording body 39 is not varied but only the diameter of the recording body can be varied greatly. In such a way, a half tone image of a high gradient can be formed.

Title: Small-sized airtight vessel
Inventor: KUNIMOTO TAKESHI
IPC: B23K26/21
Filed: 1990-05-29
Abstract: PURPOSE:To suppress a thermal effect such as the occurrence of a warp to the minimum and to reduce the quantity of heat required for welding by tapering away an end of a cover so that the periphery which is made to a weld zone becomes thinnier. CONSTITUTION:Melting of the cover 2 is reduced and sufficient heat is also transmitted to the vessel 1, and thermal welding can be performed with the minimum quantity of heat by tapering away the end of the cover. When an angle of a taper becomes larger, since a molten region of the cover is extended, it is necessary to increase the output and the heat effect is easily produced to that extent. When the taper has the angle of >=60 deg., the warp quantity increases and when it has the angle of <=60 deg., the warp does not occurs. In addition, from the standpoint of strength, the larger angle is desirable but when the angle is 60 deg., the strength is reduced by only about ten percent in the case of 90 deg. and even in the case of 45, the strength more than seventy percent in the case of 90 deg. is held. Synthetically, the range of about 45 to 60 deg. is desirable as an optimum value of this angle.
