Title: Hot-water and water mixing device
Inventor: YONEKUBO HIROAKI
IPC: F16K11/044
Filed: 1984-03-27
Abstract: PURPOSE:To supply a mixed hot-water at a stable temperature even if water pressure or hot-water pressure changes suddenly by comparing the preset value of a mixed hot-water temperature with the temperature of mixed hot-water, and the quantity of hot-water with the quantity of water to control a ratio control valve. CONSTITUTION:In a ratio control valve control device 32, usually a signal of a mixed hot-water temperature detector 21 is compared with a signal of a mixed hot-water temperature setting device 33, and a motor 30 is driven at a speed proportional to a deviation in temperature. If pressure changes on the hot-water side or the water side, and the quantity of hot-water or water changes suddenly, so that the mixing ratio is wrong, a hot-water quantity detector 18 and a water quantity detector 19 detect a change, and a ratio control valve 20 performs the correcting motion to a position where the mixing ratio gets to the initial ratio. In this case, the ratio control valve control device 32 is adapted to discriminate whether the preset value of the mixed hot-water temperature setting device is changed or not.

Title: Automatic voltage regulator of ac generator
Inventor: NAKAI AKIRA
IPC: H02P9/30
Filed: 1983-04-07
Abstract: PURPOSE:To enhance the responsiveness of an automatic voltage regulator of an AC generator by charging or discharging an auxiliary capacitor at every half wave of the output voltage, and controlling the phase of a field current when the voltage during discharging reaches the set value. CONSTITUTION:An auxiliary capacitor 26 is charged by the output of a variable resistor 22 in case of the negative half voltage of the output voltage V0 of a generator, and discharged through a variable resistor 42 at the positive half wave time. Since the charging voltage Va of the capacitor 26 is low at the starting time, the main capacitor 34 starts charging in the positive half cycle, the charging voltage immediately reaches the breakover voltage of a unidirectional switch 44 to fire a thyristor 16. Since the charging voltage Va becomes high at the normal operation time, a transistor 40 becomes ON. Thus, after the transistor 40 becomes OFF in the positive half cycle, the main capacitor 34 starts charging to control the firing phase of the thyristor 16.

Title: Nozzle case
Inventor: HIROSE HITOSHI
IPC: B05B1/02
Filed: 1995-02-24
Abstract: PURPOSE: To prevent the occurrence of shrink of a skin part at molding time in a nozzle case having a two-layer structure by superposing a soft synthetic resin skin on an outer peripheral surface and an inner peripheral surface of a core. CONSTITUTION: A nozzle case 1 is formed as a two-layer structure by integrally molding a skin 9 composed of soft synthetic resin to form a prescribed external shape on an outer peripheral surface and an inner peripheral surface of an almost cylindrical core 8 where a through hole penetrating in the vertical direction is formed in an axial part. A nozzle 3 to blow out wash water is fitted and fixed to an upper end part of this nozzle case 1, and a connecting pipe 4 to introduce the wash water is installed in a lower end part.  Since the nozzle case is formed in a two-layer structure that the core 8 being a core material of the nozzle case 1 is completely embedded in the skin 9 composed of a soft synthetic resin material, the core 8 itself can be molded by using an inexpensive material such as a scrap material, and molding time is shortened, and the occurrence of shrink can be completely prevented, and common use as the core material to the nozzle case of various shapes is promoted, and metal mold cost can be reduced.

Title: Image forming device
Inventor: NAGAO ONORI
IPC: G03G15/00
Filed: 1990-03-12
Abstract: PURPOSE:To obtain a good-quality image by changing developing bias or chang ing the electrostatic charging potential of a photosensitive body based on the cause of the lowering of image density in the case of multiply developing the same electrostatic latent image. CONSTITUTION:A latent image P1 is formed on a photosensitive body 1 by pattern latent image forming means 2 and 9 and developed by a developing device 10 to form a toner pattern image TP1. By adding bias in the same polari ty as the electrostatically charged polarity of toner to the developing device 10, a toner pattern image TP2 is formed on the photosensitive body. The respec tive image densities D1 and D2 are detected by an image density measuring means 17 and compared with reference densities DA and DB by a comparator 102. In the case of D1<DB, a controller 100 adjusts the developing bias VB1 of the developing device 10 to adjust contrast to be low. In the case of D1<DA and D2>DB, the electrostatic charging potential V0 of the photosensitive body 1 is made high. Since the cause of the lowering of the image density is examined and the developing bias or the electrostatic charging potential of the photosensi tive body is changed, the toner is not supplied to the developer with proper toner concentration and the good quality image is obtained.
