Title: Read switch for manual optical reader
Inventor: KURODA AKIYOSHI
IPC: H04N1/04
Filed: 1990-09-03
Abstract: PURPOSE:To eliminate the need for keeping a switch button to be depressed in the operation and to eliminate the need for push stroke until the start of operation by providing an electric contact to each of a push part and a main body and detecting noncontinuity in the operation state so as to start the read automatically. CONSTITUTION:A read switch consists of both a push switch contact 7 and a device main body switch contact 8. The push switch contact 7 is fixed to a gear guide board 4 and the device main body switch contact 8 is fixed to the manual optical reader main body. The gear guide board 4 going to the left by a return spring 5 is stopped by contact of both the contacts. The gear guide board 4 is similarly moved by pushing a drive wheel 2 in the operation to part the push switch contact 7 and the device main body switch contact 8. Since both the contacts in the continuity state in the non-operation is nonconductive in the operation, the nonconduction is detected to start reading. Thus, the load of the user to keep the switch pushing in the operation is relieved and the switch push stroke is not required.

Title: Photodetecting element for light measurement of camera
Inventor: TAKAGI TADAO
IPC: G03B7/099
Filed: 1987-09-16
Abstract: PURPOSE:To improve the accuracy of the sensitivity distribution of insensitive areas on the photodetector to incident light by distributing the plural insensitive areas which are insensitive to light and have a specific density distribution on the photosensitive surface of the photodetector. CONSTITUTION:An N-type semiconductor substrate is coated with a resist material and its surface is covered with a mask having holes at positions corresponding to the insensitive areas 22. The insensitive areas 22 are distributed more on the ceiling side. The density distribution is realized by varying the number of circular holes per unit area so that the distribution becomes rougher almost from the center of the incidence intensity distribution to the periphery corresponding to the intensity distribution of the incident light. Holes are bored in the resist materials by photoetching, a P-type diffusion layer is formed in an atmosphere of P-type impurities, and the resist material is removed. Areas except the P-type diffusion layer are insensitive areas 22.

Title: Gas hot water supplier
Inventor: TAKECHI HIROSHI
IPC: F24H1/00
Filed: 1985-10-18
Abstract: PURPOSE:To provide a hot water supplier capable of obtaining hot water of an arbitrary temperature by other tap even during the hot water pouring into a bathtub by changing the temperature of poured hot water upon unusing the other tap when the temperature of pouring hot water is changed by other tap. CONSTITUTION:In the case of supplying hot water by use of other tap, when a water tap is opened, and a water quantity sensor 15 detects the quantity of water passing through a heat exchanger 14 and discriminates the flow quantity more than the ignition water quantity, a gas main valve 11 and a gas proportional control valve 12 are opened, and a burner 13 is ignited and water entering into the heat exchanger 14 is heated and hot water is poured. When hot water is supplied to a bathtub 17, first, the supply hot water quantity and supply hot water temperature are set by a pouring hot water circuit 20, and a water valve 18 is opened and hot water is poured into the bathtub 17. When the water quantity of the water quantity sensor 16 becomes coincident with that of the water quantity sensor 15, the temperature of supply hot water from the heat exchanger 14 becomes equal to the set temperature of pouring hot water. Upon the simultaneous use of pouring water and other tap, the water quantity detected by the water quantity sensor 15 and that detected by the water quantity sensor 16 are different from each other whereby discrimination is possible. In a case when the set temperature with the other tap is different from the pouring hot water temperature, the set temperature at the other tap is allowed to have a priority. The hot water pouring circuit calculates and operates so that the set temperature is changed thereby the temperature of the bathtub 17 becomes equal to the pouring hot water set temperature when the use of other tap is terminated.

IPC: F24F13/32
Filed: 1988-09-19
Abstract: PURPOSE:To promote ease and secureness in locking a unit in place and safety of the installation work by providing stopping pieces, which project from the underside of the air-circulating indoor section of an L-shaped integral type air conditioner, as means for provisionally fastening the air conditioner to a window frame. CONSTITUTION:A fixing member 21 extends substantially in the L-shape downward from a mounting frame 2 to fix it securely to a window frame 41. The degree of the outward protrusion can be adjusted by turning an adjusting bolt 28. A locking protrusion 15 projecting from an L-shaped integral type air conditioner is fitted into an entry 26 in the mounting frame 2 and slid into a slit 23 formed in the upper guide section 22. The air conditioner, having its locking protrusions 15 in the respective slits 23, is moved toward the outside. The air conditioner is pushed further toward the outside until it reaches an arc arc-shaped section 33 and from thence allowed to fall along a downward guide 27. Then, the L-shaped integral type air conditioner can be fastened provisionally to the window frame by means of stopping pieces 14 projecting perpendicularly downward from its air-circulating indoor section 12. Therefore, it becomes possible for even one worker to handle the installation safely and securely alone.
